Lauterbachii (Lauterbach’s) fl. dark brownish-red on the outer surface, emeraldgreen on the inner, large, and, as well as the leaves and stems, hairy. 1896) In Monatsschritt fur Kakeenkunde 1 (1896) 7-8. K. Schumann. Hoya Lauterbachii K. Sch. eine neue Wachsblume. Von K. Schumann. (Mit einer Abbildung) Allen Erwachsenen ist von ihrer Kindheit her wohl noch in lebhafter Erinnerung. Dasz eine Wachsblume (Hoya carnosa R. Br.) zu den unentbehrlichen Zimmerblumen gehörte und mit dem Rosenkraut (Pelargonium roseum Ait.). einer Fetthenne (Sedum Sieboldii Sweet), dem Oleander (Nerium Oeander L.) und der Fuchsia den eisernen Bestand dieser Pfieglinge ausmachte. Manche dieser Pflanzen ist dem Wusche nach Abwechselungen, den Launen der Mode zum Opfer gefallen und wird nur noch recht selten angetroffen; andere haben im Wechsel der Zeiten Bestand gezeigt. Zu den ersteren gehört auch die Wachsblume, Welche nur noch hier und da einmal gesehen wird. Und doch verdiente sie wegen ihrer leichten Vermehrung durch Stecklinge, ihres willigen Wachstums und ihres reichlichen Blühvermögens eine erhöhte und erneute Beachtung. Zudem rechnet sie in die Familie der Asclepiadaceen, welche wir erst vor kurzem in einem eigenartigen Vertreter der Heurnia macrocarpa Schweinfurth kennen gelernt und besprochen haben, und welche wegen ihrer merkwürdigen Blütenbildung ein so lebhaftes Interesse erwecken. Die Gattung Hoya hat aber noch eine grosze Auzahl zum Teil prachtvoller Zierpflanzen des Warmhauses geliefert, so gehört H. imperialis Lindl, zweifellos eine der auffallendsten Pflanzen mit grossen hängenden Dolden dunkelbruner, groszer Blüten hierher. Keine der bisher beschriebenen, wohl nahe an hundert heraureichenden Arten kann sich mit einer neuen Art en Schönheit der Blüten messen, welche Herr Dr Lauterbach vor vier Jahren aus Neu-Guinea mitgebracht hat, und die er mir zur Beschreibung anvertraut hat. Der erwähnte Reisende, welcher auf seinem Gute zu Stabelwitz bei Breslau eifligst der Pflanzenkunde und Pflege obliegt, ist auch ein groszer Freund und Kenner der Kakteen. Hoya Lauterbachii K. Sch. ist eine Liane, welche im Gegensatz zu den meisten Arten der Gattung behaart ist, Die ziemlich dünnen, einzelligen, geschlängelten Haare bilden an deu jüngeren, stielrunden Asten, sowie besonders auf der Rückseite der Blätter eine welche Bekleidung. Die letzteren sind 2—3cm lang gestielt; ihre Gestalt ist oblong, elliptisch oder bisweilen umgekehrt eiförmig elliptisch, sie sind kurz und spitz zugespitzt, am Grunde gerundet und von fleischiger Beschaffenheit. Die hängenden, doldenförmigen Blütenstande sind wenig-meist vierblütig; sie werden von einem bis 10 cm langen Stiele gestützt und auch die Blüten sind ziemlich lang (bis 8 cm) gestielt. Die etwas dünneren Blütenstiele sind ebenfalls wie die Blütenstandstiele meist behaart. Der Kelch miszt etwa 1 cm in der Länge, die Kelcblätter sind dreiseitigeiförmig bis oblong und spitz. Die Blumenkrone ist schüsselförmig, hat bis 7.5 cm im Durchmesser; sie ist beiderseitig dicht

364

sammetig behaart; dabei kontrastiert die innere, dunkelbraunrote mit der äuszeren, smaragdgünen Farbe auf das lebhafteste, so dasz wir hier zweifellos eine der schönsten Blütenswikungen vor uns haben. Der Befruchtungsapparat, des Gynosteg, nimmt den Boden der Blume ein; es hat 15 mm im Durchmesser. Die Coronaschuppen sind fleischig, auf der Stirnseite etwas vertieft und schnabelförmig über den Narbenkopf gezogen. Die Staubgefäsze haben ein ziemlich auffallendes, häutiges, schneeweiszes Anhängsel. Herr Dr. Lauterbach fand die Pflanze am 10. November l890 am Gogol-Flusse. Bisher ist eine Art, welche sich durch derartige Dimensionen der Blüten kennzeichnet, weder in Neu-Guinea, noch sonst an einem Orte des östlichen Asiens gefunden worden. Wir wollen hoffen, dasz die Pflanze von der demnächst nach Kaiser-Wilhelmsland abgehenden Expedition, welche von Herrn Dr. Lauterbach geleitet werden wird, von neuem aufgefunden und nach Deutschland eingeführt wird. Translation: All adults probably still remember, vividly from their childhood, that a Wax Plant belonged to indispensable indoor plants and together with the Geranium (Pelargonium roseum, Ait.), a Sedum (Sedum sieboldii, Sweet), the Oleander (Nerium oleander, L. ) and the Fuchsia they formed the continued existence of these "foster children". The desire for a change or the fashion trends let some of these plants disappear and it is difficult to find them now days - others provided consistency over time. The Wax Plant belongs to the first mentioned group and it can be seen only occasionally today. But it still received a higher and renewed attention because of its easy propagation with cuttings, its willingness to grow and its ample flowering. Furthermore, it belongs to the family of the Asclepiadaceae which we most recently got to know and discussed the peculiar representative Heurnia macrocarpa Schw., which is rather interesting because of its strange flower production. The genus Hoya has furnished a lot of hothouse plants some of which are splendid. One of them is H. imperialis, Lindl., unquestionably one of the most striking plants, with large hanging umbels of dark brown, big flowers. None of the almost 100, so far described species, are a match for this new species considering the beauty of the flowers. Dr. Lauterbach brought it back from New Guinea four years ago and entrusted the description to me. The mentioned traveler, who applies himself to a great extent to plants and their care at his estate 'Zu Stabelwitz', near Breslau, is also a great lover and expert of cactus.

Hoya Lauterbachii K. Schumann is a vine, which is antithesis to the main species of the Genus. The fairly thin, unicellular, tortuous hairs form a soft covering over the younger terete branches, as also especially on the undersides of the leaves. The latter are 2-3 cm long stalked; their shape is oblong, elliptic or occasionally inverse ovate-elliptic, they are short and sharply acuminate, rounded at the base and of a fleshy nature. The pendant, umbelliform inflorescences are more or less four-flowered; they are supported by a peduncle up to 10 cm long and the flowers are also fairly long-stalked (up to 8 cm). The somewhat thinner pedicels are, like the peduncles, usually hairy. the calyx measures approximately 1 cm in length, the sepals are triangular-ovoid to oblong and acute. The corolla is bowl-shaped up to 7.5 cm in diameter; it is densely velvety-hairy on both sides; hence the inner dark red brown contrasts with the-outer emerald green color of the most vivid, so that we have here certainly one of the most beautiful of floral effects. The fertilization apparatus, the gynostegium, occupies the base of the flower; it is 15 mm in diameter. The corona scales are fleshy, somewhat depressed at the front and

365

extended beak-like over the stigma-head. The stamens have a fairly striking, snow-white, membranous appendage. Dr. Lauterbach found the plant on the 10th November 1890 on the River Gogol. Until now no species has been found, characterized by such dimensions of the flowers, neither in New Guinea, nor besides at a single place in eastern Asia. We would like to hope that the plant is again discovered and introduced to Germany by the next expedition to go off to Northeastern New Guinea, which will be lead by Dr. Lauterbach.

My two collections exactly match the type. This is a very distinct species characterized by its oblong-lanceolate leaves with pubescent indumentum and its rotundate exterior end of the coronal lobes. It cannot be confused with H. carnosa, which belongs to a different series of the section. In the leaves alone it may be referred to H. lancilimba forma Tsoi which has glabrous leaves and much larger flowers. A photograph in our herbarium taken from a Kew specimen, J. Cavalerie 3484 collected from Lo-fou, Kweichow, labeled Hoya Esquirolii ? apparently represents Hoya Lyi. As Cavalerie 3484 is the type number of Dischidia esquirolii (Levl.)

(Physostemma) clandestine, which I found in each mountain locality In Java, and in like manner is possessed with nerved leaves.—Stalks somewhat branched rooting in trees, about a small finger thick, round, warty, dirty gray. Leaves opposite, but internodes moderately far apart; petioles thick, round, twisted, randomly covered with wart like outgrowths 1 to 1 1/2 inches long, 6 to 8 inches long, 2 1/2 to 4 inches wide, ovate or elliptic-oblong, rarely ovate-lanceolate, more or less acuminate, base rounded, from which not very prominent swellings at the apex, the three longitudinal nerves are not very prominent and transverse reticulations are lax and obscure, fleshy, flat, with margins revolute only when dried, above indistinctly green and paler below. Peduncles compact, two to five, between the petioles, at the same internode, or often on juvenile branches, far removed from the leaves, 2 to 3 times longer then the petioles, very wide spreading or slightly drooping, purple, glabrous, thickened above, exhibiting a rachis covered with wart-like projections gradually becoming clavate-elongate, around the periphery close spaced pedicels in an amble 3/4 to 1 inch long, slender, purple, puberulous, very short and scabrous, one flower per floret after flowering, and fall leaving scars on the rachis, flowers at the center at the very apex of the rachis begin to open and at length evolve. The flowers are the size and the shape similar to of the staminal corona of Hoya carnosa.

Blume de historic voorgedragen en afbeeldingen gegeven heeft in zijne Rumphia. Naar aanleiding van dat werk zullen wij ook die gewassen, voor zoo verre zij in de tuinen zijn ingevoerd, hier vermelden. H. macrophylla Bl. may, wegens hare groote bladen, dezen naam tergt verdienen. Zij zijn namelijk 6-8 duimen lang en 2 l/2 - 4 duimen breed (Rijnl.). Zij hebben drie zeer sterken nerven, en de stengels en stelen zijn met eigenaardige klieren bezet. De bloemen hebben de grootte van die van H. carnosa. Van deze plant geeft de pleat 185 der Rumphia eene prachtige afbeelding. Zij komt op Java voor in de bosschen van Buitenzorg, en is aldaar door. Blume ontdekt in 1820. Aug. van Gheert, te Gend, geeft hear als bij hem voorhanden op. in zijnen Catalogus van 1854. Translation: The large-leafed Hoya is one of the cleanest from it island Java, which one until now from this having been small, and of which Dr. C. L. Blume the historic nominated and images given in his Rumphia. To occasionally from that work shall we even those crops, for so they are being imported into the gardens, here mentioned. H. macrophylla Blume may, because of its large leaves, thus earn the name correctly. They being namely 6-8 inches long and 2 l/2 - 4 inches broad (Rijnl.).They have three very strong nerves, and the main one and the position being engaged with its own nice small ones. The flowers has the magnitude of those from H. carnosa. From these plants of the plate 185 of Rumphia are magnificently pictured. They come up from Java to the botanical garden of Buitenzorg, and are there. Blume discovered it in 1820. Augustus van Gheert, to Gend, described hear by him before hand in a new Catalog from 1854.

Hoya manipurensis Deb 1955 Type description: In The Journal of Indian Botanical Society XXXIV (1955) 50-52. D. B. Deb. A New species of Hoya from Manipur, Department of Botany, D. M. College, Imphal, Manipur, Assam. While exploring the flora of Manipur, the author collected a specimen of Hoya, very different from all recorded species. On subsequent and thorough examination at the Herbarium, Indian Botanic Garden, Calcutta, the author was convinced that the specimen has specific characteristics of its own, different from any, hitherto described. It is described as a new species below. Hoya manipurensis Deb. sp. nov. Proxime accedit Hoyae acuminatae Benth., sect. Pterostelma, a qua tamen divert praecipue foliis obovatis truncatisque, floribus multo minoribus, pubescentia utriusque paginae petalorum. Planta parva, epiphytica; caulis luteolus, ca. 34-35 cm. longus, lignosus, teres, ramosus ex basi, nodis tenuiter tumescentibus; parses juniores pubescentes. Folia simplicia, opposite, decussata, crassa, coriacea, puberula exstipulata, petiolata, obovata, truncate, pallide grisea colore, nervis obscuris 3-5 primo parallelis, demum ad apicem divergentibus; apice aliquantum depresso et mucronato; basi acute, attenuate; marginibus integris; petiolis pubescentibus, 2-4mm. longis; lamina 3-4.5 cm. longa, 2-2.5 cm. lata. inflorescentia axillaris et terminalis, umbellate, cymosa, pauciflora, pedunculata; pedunculis brevibus, usque 2 mm. longis, validis, tuberculatis ad florum insertionem. Flores parvi, regulares, hermaphroditi, hypogyni, gamopetali, pedicellati, pediculis tenuibus, 3-4 mm. longis, ebracteatis; pedunculis atque pediculis pubecentibus. Calyx 5-partius, ornatus 5 squamis glandularibus, imbricatus, pallide viridis, ovatus, 2 mm. longus, 0.75 mm. latus, acutus, dense pubescens extus, nervis obscuris. Corolla gamopetala, 6. 5-7 mm. longa, tubularis, angularis prope basim; laciniae 5, sepalis oppositae, carnosae, convexae, valvatae in atabastro, acutae, nervis obscuris, dense pubescentes in utraque pagina; multo magis in interiore pagina, pilisque longioribus, obscure albae colore. Corona constans 5 processibus carnosis corneisque adnatis columnae staminali, stellate adscendentibus, concavis in superiore pagina, marginibus recurvatis vacuumque spatium includentibus, angulo interiore producto in calcar quod antherae incubi". Columna staminalis brevis, antherae conniventes supra styli apicem in appendicem membranaceam; pollinia erecta, cerea, solitaria in singulis linearia, sub 1 mm. longa, pedicellata. Carpella 2, stylus unicus, apice 5-angulato, extremo vero apice tenuiter apiculato; ovaria 2, sessilia, glabra, 8 mm. longa, oblongo-conica, placenta marginal. Fructus non vrisus. Hoya manipurensis Deb sp. nov. (sec. Pterostelma). Relationship,—This comes very near to H. acuminata Benth. (section Pterostelma) from which it can be readily distinguished by obovate truncate leaves, much smaller flowers, and pubescence of petals on both the surfaces. Plant small epiphytic; stem yellowish, about 34-35 cm. long, woody, round, producing several branches from the base, nodes slightly swollen; younger parts pubescent. Leaves simple, opposite, decussate, thick, coriaceous, puberulous, exstipulate,

Manipur, Litan, alt 3000 ft., 1-9-1953; epiphytic on Ficus glomerata Rob., D. B. Deb (No. 1081). After preparation of this manuscript the author found out a herbarium sheet from Assam sent to the Indian Botanical Garden for identification. The specimen was examined and proved to be the same as the new species here described. Flora of Assam Umsaw, 1612-1949, No. Misc./8. Thus it appears that the range of distribution of this new species extends to Khasia Hills, Assam. The type sheet has been presented to the Herbarium, Indian Botanical Garden, Calcutta, where the identification of the specimen was cared out. The author expresses his thanks to the Rev. Dr. H. Santapau, Chief Botanist, Botanical Survey of India, Calcutta, for kindly preparing the Latin translation of the description of the species.

It is noteworthy that H. megalantha has thus far been collected only in four widely separated montane areas. Although having no foliage features which distinguish it from such species as H. vitiensis, H. megalantha is very distinct on the basis of floral characters mentioned in the key.

The large, cyathiform corolla is rich pink to deep purple, as are the calyx lobes. Flowers have been obtained in all months between December and June. Typification: The species is based on im Thurn F6 (K Holotype), composed of specimens from two localities: from Mt. Mbuke Levu, Kandavu, on April 4, 1905, and from Mt. Tomanivi, Mba Province, Viti Levu, on May 1, 1905. A note on the K sheet

439

indicates that the two collections were carelessly mixed. Both parts bear flowers and it is not now possible to separate them; therefore the mixture must be taken as the holotype. Distribution: Endemic to Fiji and known from four of the high islands. Local name: Ndraumbimbi (Taveuni). Available collections: Viti Levu: Mba: Mt. Tomanivi, DA 7122, 12718 (Melville et al. 7107). Namosi: Track to Mt. Vakarongasiu, DA 17608. Natasiri: Between Navai and Nasonggo, DA 15302. Vanua Levu: Mbua: Navotuvotu, summit of Mt. Seatura, Smith 1649. Taveuni: Mountain slopes east of Somosomo, Gillespie 4815. DA 17384: borders of lake east of Somosomo, Smith 863. This upland endemic is the most striking and most distinct species of the genus in the Fijian Region; its large, richly colored flowers at once distinguish it.

Falls die Vermutung Burkills zutrisst, dasz seine H. subcalva Burkill mit H. megalaster Warb. identisch ist, so musz der erstere Namen an Stelle des Warburgschen treten, da H. megalaster Warb.

Note: It has been stated that H. megalaster Warburg was first published in 1901, without description, whereas H. subcalva Burkill was published the same year with a full description, but supposedly cited a type number that did not exist. In Hoyas of Northeastern New Guinea (1992) 93. R. D. Kloppenburg. (Translation of Die Asclepiadaceen von Deutsch Neu-Guinea by Dr. R. Schlechter). 45. Hoya megalaster Warburg in Fedde, Repert.. III (1907) p. 334 - H. purpurea K. Schumann in Engler's Jahrbücher IX (1887) p. 216 (not of Blume). Northeastern New Guinea: on the upper part of Empress Augusta River (M. Hollrung #258); in the forests on the way from Ramu to the coast about 400 meters altitude (Schlechter #14148 - Blooming in January 1902); in the forests of the Ibo Mountains near Boroai, about 700 meters altitude (Schlechter #18276 - Blooming in September 1909); in the forests at the foot of the Bismarck Mountains, near the Saugueti -Etappe (Military rest area) about 300 meters altitude (Schlechter #18664 - Blooming in November 1908). I have brought a few very good examples of this magnificent plant. The blooms are even still larger on this one than the original, but not quite complete, but they agree with that one and with the blooms gathered by me in the Year 1902. The species has the largest blooms in the Section and through the corona scales, that are sharply keeled above, distinguishable from the others. With few examples on the Ibo I found leaves 20 cm. long by 8.5 cm. wide. The blooms reach a diameter of 5 cm.. The bloom coloring is dark wine red. If Burkhill's assumption is true, that his H. subcalva Burkhill is identical to H. megalaster Warburg, then the first name must stand, for Warburg's treatment (appearance) of H. megalaster Warburg has been known in the literature for many years, but was not published with a description until the year 1907. In The Hoya Handbook (1992) 78. D. Kloppenburg & A. Wayman. Hoya megalaster Warburg. Crabs claws for dinner ? Here is another spectacular species from New Guinea and neighboring parts of North Eastern Australia. This species was first published by Dr. Warburg in 1907. One of the differing characteristics of this species is the narrow star shaped corona lobes (central part of the flower) which are plainly visible in our photograph. Not only are the flowers large, distinctive and strikingly beautiful, but the foliage is deep green and attractive. Once established it is a strong and rampant grower. Again plants with long internodes will be most attractive if pinched back to force branching, or wrapped back upon themselves. If you don't keep this one under control, once it begins strong growth, it will find its way to the nearest light source. In the greenhouse it will quickly reach the peak of the roof, seeking additional light. I have seen these plants attractively trained on wire tomato trellises, wrapped in and out and around to yield a beautiful plant. When a plant like this blooms with 3-7 large flowers bring in all your friends to see it. It is a knock out ! If you have extra room root some cuttings from the trimmed ends to give to friends and to insure against loss of the original plant. Occasionally mature hoya plants will die for no good visible reason. If a plans looks sick take some cuttings immediately as insurance against the mother plants possible loss.

This species has some beautiful flower color variations, so don't settle for just one if you have the room. There are some almost black red types that are certainly worth sneaking out.

Friends of mine took along specimens of the flowers and leaves to Dr. D. V. Field who is studying the Asclepiadaceae at Kew) and he very kindly took time to investigate it

and then informed me that it was not a hoya at all but a Dischidia. Obviously he did not want to commit himself any further at that stage but I have now been informed that he considers it to be Dischidia squamulosa.

Comments: Dr. Schlechter placed this species at the beginning of his Eu-Hoya Section II. He stated "This and the following two species I have placed at the beginning of this section, since their habit and small flower size, are closest to the section Otostemma". This is his species following H. eitapensis Schltr. He further states "This species always has leaves and blooms smaller then Hoya eitapensis Schlechter, moreover the pubescence on the inside of the corolla is different. Hoya microstemma Schlechter is the smallest species of the section in the area, and one in which we are most knowledgeable. Its blooms are flesh colored with rose-red corona". It is obvious that this bilobed species belongs in the section Acanthostemma (Bl.) Kloppenburg, and not in section Hoya or the non sulcate section Otostemma (Bl.) Miquel. I have also placed this species in the Subsection Angusticarinatae Kloppenburg. References: Kloppenburg in Hoyas of Northeastern New Guinea, ORCA Pub. Co. (1992) 21-22. A.

(Plants of the Gazelle Expedition). Hoya neo-guineensis, Engl.; caulis scandentis internodiis longis; foliis petiolo 3—4-plo breviore leviter canaliculato suffultis, oblongo-ovatis, basi obtusis, subtruncatis, distincte acuminatis acutis, nervis lateralibus utrinque circ. 6 tenuibus subtus (in foliis siccis tantum) vix prominulis; inflorescentia umbelliformi pedunculo, petiolum superante suffulta; pedicellis tenuibus pedunculum: aequantibus; floribus magnis; calycis segmentis ovatis cinereo-pilosis et minute ciliatis quam corolla rotata sexies brevioribus; corollae magnae intus dense et brevissime pilosae tubo brevissimo amplo, lobis late triangularibus patentibus; coronae staminalis appendicibus dorsalibus crassis inflatis, nitidis, obovatis, margine dorsali et apiculo adsendentibus, laminis antheriferis, oblongo-semiovatis, loculis linearibus; polliniis oblongo-claviformibus; folliculis oblongis, attenuatis. Scandens. Ramulorum internodia circ. 1.2—1.l cm longa, foliorum petiolus 5—2 cm longus, lamina 6—7 cm longa, 3—3.5 cm lata, acumine 8 mm longo instructa. Pedunculi circ. 22.5 cm, pedicle 1.5—2 cm longi. Calycis segmenta 2.5 mm longa. Corolla circ. 4 cm diametiens, pelvaeformis extus viridis, intus atropurpurea, minute holosericeo-pilosa. Corona staminalis 6 mm diametiens, brunnea nitida. Diese schöne Art steht der H. coronaria Bl., welche mit H. velutina Wight identisch ist, nahe, unterscheidet sich aber wesentlich durch die groszen Corollen und die kleinere von den Staubblättern gebildete Nebenkrone. Während bei H. coronaria der Durchmesser der Blumenkrone nur 2.5 cm, der “Nebenkrone” 1 cm beträgt, also ein Verhältnis von 2.5 cm, 1 besteht, ist bei unserer Art das Verhältnis derselben Teile wie ist 0.6. Zudem sind die Abschnitte der Corolle bei H. coronaria gleichseitig dreieckig, bei unserer Art breit dreieckig. Ins. Neu-Guinea, fretum Galewoanum (24. 6. 75). Translation: stalk climbing with long internodes; leaves supported by lightly channeled petioles 3 to 4 times shorter than the leaves, oblong-ovate with obtuse bases, almost truncate, distinguished by long acute accumulation, having about 6 thin lateral nerves on each side below (on dried leaves only) scarcely prominent. Inflorescence in an umbel supported by a peduncle above the petiole; pedicels thin and equal in length to the peduncle; flowers large; calyx segments ovate ash-gray-pilose and minutely ciliate, 6 times smaller than the rotate corolla. With a large corolla inside densely and very shortly pilose, tube very short large; lobes broadly triangular and widely spreading; parts of the staminal corona at the outer angle thickly inflated, shining, obovate, dorsal margins and apex ascending, anther blade oblong-semiovate, with lateral locules; pollinia oblong-club shaped ; follicles oblong, attenuate. Climbing. Branching with internodes about 1.2 to 1.4 cm long. Blade of the petiole 1.5 to 2 cm long, blade 6 to 7 cm long by 3 to 3.5 cm wide, provided with an 8 mm long acumine. Calyx segments 2.5 mm long. Corolla about 4 cm in diameter, basin shaped outside green, inside dark purple, minutely, finely and entirely silky-pilose. Corona stamens 6 mm in diameter, shiny brown.

This beautiful species is near H. coronaria Bl. which is identical to H. velutina Wight, but is distinguishable by its larger corolla and the smaller staminal corona. Whereas with H. coronaria the diameter of the corona is only 2.5 cm, the corona lobes 1 cm, thus the ratio is 2.5 to 1 overall, with our species the ratio is 4 to 0.6. In addition a segment of the corolla of H. coronaria is an equilateral triangle, while our in species the corolla segments are broad triangular. In New Guinea, strait of Galewoanum 24 June 1875.

This is a specimen in the Banksian herbarium, either named by Roxburgh, or supposed to be the same with his plant, to which Mr. Brown has attached the name of H. Nicobarica (Br. mst.); but Roxburgh has expressly mentioned that his plant is a “native of the mountainous part of the Circars,” while that named by Mr. Brown seems to have come from the Nicobar islands, to the north of Sumatra: although we saw this specimen, yet unfortunately we neither examined it with attention, nor made any notes upon it; if, however, our recollection serves us rightly it appeared more allied to, if not the same with H.

It appears to be different from any species included in Fl. Brit.

Inter species australienses Hoya australis affinis foliis utrinque plus minusve glabris facile distinguenda. Type. Queensland Davies Creek, E. of Mareeba, D. Diddle NSW 193413 (halo: NSWt; ISO: BRI, K. L). Greek oligos. ‘few'. thrix. trichos, 'hairs', referring to the almost glabrous stems and leaves of this plant. There are two subspecies, both endemic in Australia. Key to the subspecies. 1 New shoots distinctly loosely pubescent subsp. oligotricha. 1 * New shoots glabrous subsp. tenuipes. 6a. Hoya oligotricha subsp. oligotricha A vigorous, glabrous or very sparsely and loosely pubescent lithophytic or terrestrial twiner or shrub. Leaves fleshy, broadly pinnately veined, elliptical, ovate or orbicular, 4-12 cm long, 3.0-8:0 cm wide; petioles 1.0-3.5 cm long, 3-7 mm diam. Peduncles 0.5-2.5 cm long, rhachis cylindrical. Pedicels 1.5-3.0 cm long; slender. Umbels 12-30-flowered. Sepals broadly triangular, 2-4 mm long. Corolla campanulate, minutely puberulous within, creamy-white with a pink or red spot at the base of each lobe, 1.5-2.5 cm diam. Corona to 4 mm diam., white; segments ovate, concave above, with two longitudinal, inrolled keels extending the full length below, inner angle apiculate, outer angle rounded. Fruit 10-15 cm long, 1.0-1.5 cm diam. Distinguished by the broad leaves, the loosely pubescent new growth and the short, thick peduncles. Many previous authors have mistakenly interpreted this taxon as representing H. australis (e.g. Bailey 1900). Occurs on rocky outcrops in moist forests on and around the Atherton Tableland, extending south to Townsville. A disjunct occurrence further south extends from Fraser Island south to the Kempsey district. The southern occurrence is almost exclusively coastal, on headlands and on siliceous sand in littoral rainforests or wet sclerophyll forests. Plants growing on dune systems are rooted directly into sand and usually have a long-twining, scrambling habit. Plants growing on rock outcrops are rooted in small humus accumulations, and show stronger development of the short-internode growth phase.

Type Queensland: Pascoe River Rockpile. B. Wallace 83252, 16.9.1978 (halo: NSWt; iso: E3RI. K. L). Latin tennis, ‘slender’. and pes, pedis, ‘foot’, referring to the more slender peduncles of this subspecies in comparison to the type subspecies. A vigorous lithophytic or terrestrial twiner. Leaves fleshy or coriaceous broadly pinnately veined, elliptical, narrow-ovate or narrow-obovate, 6-14 cm; long, 3.0- 7.0 cm wide; petioles 3.0-4.5 cm long, 3-7 mm diam. Peduncles 3.0-4.5 cm long, slender, rhachis cylindrical. Pedicels 1.5- 3.0 cm long, slender. Umbels 10-25-flowered. Sepals narrowly triangular, 2-4 mm long. Corolla campanulate, minutely puberulous within, creamy-white with a pink or red spot at the base of each lobe, 1.0- 2.0 cm diam. Corona to 4 mm diam., white; segments ovate, concave above, with two longitudinal, inrolled keels extending the full length below, inner angle apiculate, outer angle rounded. Fruit unknown. H. oligotricha ssp. tenuipes is distinguished within the H. australis complex by the glabrous narrow-ovate or narrow-obovate leaves and the long, slender peduncles. A taxon of rainforests of Cape York, from around the Olive River south through the Iron and Mcilwraith Ranges. No collections of H. oligotricha are known from between the southern end of the Mcilwraith Range and Cooktown, where H. oligotricha ssp. oligotricha is present. Subspecies tenuipes often occurs in deep shade in rainforests, growing as an epiphyte or lithophyte. It is sympatric with H. australis ssp. sana over much of its range. Scrub-clad rocky hills occur along the coast in areas such as the lower Pascoe River, with H. oligotricha ssp. tenuipes growing epiphytically within closed forest pockets in sheltered areas, and H. australis ssp. sana growing lithophytically on exposed rocks often only a few metres away. H. nicholsoniae often occurs with H. oligotricha ssp. tenuipes, and H. alata with H. australis ssp. sana in these situations. Selected Specimens Queensland: Hann Creek. B.

Sporadic. Terrestrial or lithophytic climber with long twining stems; young growth hairy, leaves 4-12cm x 38cm, broadly elliptical, ovate or orbicular, on petioles 1-3.5 cm long, fleshy, dark green to yellowish, glabrous; peduncles 0.5-2.5 cm Tong; umbels 12-30flowered; flowers 1.5-2.5cm across, white with a red spot on each lobe, strongly fragrant, on pedicels 1.53ctn long; follicles 10-15cm x 1-1.5cm, cylindrical. This species has 2 disjunct occurrences: northeastern Qld from the Atherton Tableland to Townsville and from Fraser Island in south-eastern Qld to Kempsey in north-eastern NSW. Northern populations grow in moist forests, often on rocky outcrops,

529

whereas in southern areas the plants are almost exclusively littoral growing in sandy soils. This species is commonly cultivated and has similar requirements to H. australis, with which it is often confused. H. australis has leaves distinctly hairy beneath whereas in H. oligotricha they are glabrous or sparsely hairy. One subspecies has been named. H. oligotricha ssp. tenuipes K. Hill Differs chiefly in having glabrous young growth, narrow-ovate to narrow-obovate leaves and longer, more slender peduncles. Flowers sporadically. Common on the eastern side of Cape York Peninsula between the Olive River and the Mcilwraith Range. Usually grows in monsoonal rainforest thickets. Has been introduced to cultivation and is quite rewarding. Has similar requirements to H. australis ssp. sana. Propagate from seed, or from cuttings, which strike readily.

Note: all these sp. and subsp. etc were combined by Forster under Hoya australis.

Leaves spreading or outspread, petiolate. lanceolate elliptic or elliptic, acuminate, base rounded, leathery texture, both sides glabrous, lucid above (shiny), below opaque, petiole glabrous, above slightly grooved. inflorescences with a slender peduncle, umbel like, 6-20 flowered, pedicels threadlike, toward the apex minutely puberulous. Flowers, in the genus medium sized. Leaflets (lobes) of the calyx ovate, obtuse, glabrous, much smaller than from the corolla. Corolla reflexed, 5 parted all the way to one fifth from the base, outside glabrous, inside minutely and reversed papillose-puberulous, lobes oblong somewhat acuminate, margins recurved. Leaflets (scales) of the corona erect above cylindrically columnar, a little thickened toward the base, in front oblong, both ends obtuse, base outside two keeled, gynostegium nearly twice as tall. Pollinia obliquely oblong, a little attenuate toward the base, with the translators very short and flattened (horizontally expanded), retinaculum rhomboid, small (puny). A pretty epiphytic vine with cordlike loosely leaved branches. Leaves 6.5-17 cm. long, near the middle 1.5-4.3 cm. wide. Petiole 0.3-0.8 cm. long, bare.

Hoya oxycoccoides S. Moore 1916 Type description: In Transactions of the Linnean Society of Botany 9 (1916) 116. S. Moore. Hoya (§ Physostelma) oxycoccoides, S. Moore, sp. nov. Caulis volubilis, tenuis, subdistanter foliosus, puberulus. Folia parvula, petiolata, obovata, nonnunquam fere suborbicularia, rotundata, apice mucronata, basi breviter cuneatim angustata margine recurva, coriacea, supra optime reticulata, utrinque glabra, 12-18 x 7-9 mm. Umbellae circa 6-floae, pedunculis gracilibus puberulis folia longe excedentibus 5-6 cm longis fultae; pedicelli pedunculis breviores, glabri circa 2 cm. longi. Calycis segmenta parva, oblongo-ovata, obtusa, ciliolata, 1.5 mm. longa. Corolla paullulum ultra medium lobata, 2 cm. diam.; lobi deltoideo-ovati, obtusi, intus margine dense pubescentes, ceteroquin glabri, 6 mm. longi. Coronae phylla crassa, subhorizontalia (sc. breviter ascendentia), apice (interne) erecta, acute, superne obovata, medio concava, postice obtusissima, lateribus rotundatis, crassiusculis. Pollinia oblonga, obtusa; glandula oblonga, caudiculis circiter aequilonga. Camps III to VIII; 2500 to 4900 ft. Leaves bright green and faintly shining above when dry, opaque and pale below; petioles 3-5 mm. long, puberulous. Pollinia 0.5 mm. gland 0.15 mm long. This is evidently closely allied to. H. microphylla; Schlechter and H. pulchella, Schlechter, as Schlechter’s figure and descriptions show, but it has certain points of difference which seem to prevent its being considered conspecific with either; these differences are shown in the accompanying table. As Schlechter observes, the leaves of these and one or two other species greatly resemble those of Dischidia. (In Table form the following is presented here in line text) Leaves Coriaceous, more or less obovate, sometimes nearly orbicular, rotundate distally. Peduncles 5-6 cm. long. Corolla 2 cm. across densely hairy along the margin. Corona Lobes obovate, 3 mm. in the radial direction. Translation: Stalk twining, slender somewhat distantly leafed, puberulous. Leaves small, petiolate, obovate, sometimes almost orbicular, rounded, apexes mucronate, bases shortly and narrowly cuneate, margins recurred, leathery, above exceedingly reticulate, both sides glabrous, 12 to 18 mm long by 7 to 9 mm. Umbels about 6-flowered, supported on slender peduncles, much longer than the leaves 5 to 6 cm. long; pedicels much shorter than peduncle, glabrous, about 2 cm. long. Calyx segments small, oblong-ovate obtuse, ciliate 1.5 mm. long. Corolla lobed to a little above the middle, 2 cm. in diameter lobes deltoid ovate, obtuse, inside margins densely pubescent, otherwise glabrous, 6 mm. long. Leaflets of the corona thick, somewhat horizontal (scales shortly ascending), apex (inner) erect, acute above, obovate, middle concave, outer very obtuse, sides rounded thickened. Pollinia oblong, obtuse; gland oblong, caudicles about of equal length. Note: here again as with his other descriptions no Type is designated nor depository.

Sch. fruticosa scandens epiphytica ramis modice validis, probabiliter teretibus exsiccatione sola subangulatis novellis ipsis glaberrimis, internodiis valde elongatis superne incrassatis; foliis breviter petiolatis ellipticis obtusis et apiculatis basi rotundatis carnosis nitidis utrinque glaberrimis; inflorescentia ex axilla altera utriusque foliorum paris umbellata dein ope rhachidis subglobosae crassae subracemose extensa; floribus pedicellatis, pedicellis gracilibus glabris; sepalis ovatis acutis; corolla rotata ultra medium in lacinias ovatas acutas divisa, glabra; gynostegio pro rata haud parva; corollae lobis horizontalibus apice et basi acuminatis excavatis; antheris ovatis membranaceo-marginatis suberectis; capite stigmatis breviter conicis. Die 80—100 cm langen, blühenden Zweige sind am Grunde 4 bis 6 mm dick und mit gelblicher Epidermis bekleidet. Der kräftige, 10 bis 13 mm lange Blattstiel ist oberseits flach; dort, wo er in die Spreite eingelenkt ist, befinden sich auf dieser mehrere Drüsen. Die Spreite ist 7—11 cm lang und in der Mitte 56.5 cm breit, an der getrockneten Spreite sind 6 kräftige Nerven rechts und links vom Medianus beiderseits deutlich sichtbar, wahrscheinlich treten sie aber nur beim Eintrocknen hervor, das auch die Spreite runzlig macht. Der Blüthenstand wird aus über 20 Blüthen znsammengesetzt; ihr Stiel ist kräftig und etwa: l cm lang; die Spindel erhält endlich einen Durchmesser von 5 mm. Die zierlichen Blüthenstielchen sind 10—15 mm lang. Der Kelch ist 1.5—2 mm lang. Die grünlichweisse Blumenkrone misst im Ganzen 5—6 mm; sie ist am Rande weiss und papillös. Das gesammte Gynostegium ist 2.5 mm lang; die Coronaschuppen haben eine Länge von 1.5 mm; das vertiefte Anhängsel misst ebensoviel in radialer Richtung. Die auf rechten Beutel sind 1 mm lang; der Narbenkopf ist 0.5 mm hoch. Kaiser Wilhelmsland: Oertzen-Gebirge, im Hochwald, 80 m ü. M. (Lauterbach n. 2041, blühend am l2. Mai 1896); Nurufluss, im Hochwald 80m ü. M. (Delselbe n.2874; blühend am 14. September 1896). Anmerkung. Die Art ist durch die sehr verlängerten Aeste, deren Zwischenknotenstücke bis 20 cm messen, kenntlich. Die Blüthen sind nicht, wie oft, stark niedergedrückt, weil die Staubgefässe hoch über den Coronaschuppen aufrecht stehen. Translation: climbing epiphytic shrub with moderately strong branches, probably round usually somewhat angular when young very glabrous, internodes very long elongated above thickened; leaves with short petioles elliptic, obtuse and apiculate with base rounded fleshy shiny both sides very glabrous; inflorescence from alternating axles and flower clustered in umbels upon which a thickened rachis is supported in an almost globose thick subraceme form; flowers pedicelled, pedicels slender glabrous; sepals ovate acute; gynostegium not at all small proportionally; lobes of the corolla hollowed out horizontal with the apex and base acuminate; anthers ovate suberect, with margins membranaceous; stigma head briefly conic.

German: The 80-100 cm long, blooming branches are 4 to 6 mm thick at the base and clad a with sallow epidermis. That strengthens, otherwise 10 to 13 mm long petiole is flat; there, where it is linked to the blade, one finds several glands on it. The blade is 711 cm long and in the middle 5-6 cm broad, on the dried blade are 6 strong nerves right and left from the midrib on both sides clearly visible, probably they are only set forward upon drying, however it also makes the blades wrinkled. The inflorescence is composed out of over 20 flowers. the stalk is vigorous and it is l cm long; the shank finally obtains a diameter of 5 mm. The dainty pedicels are 10-15 mm long. The calyx is 1.5-2 mm long. The greenish-white corolla measures in the whole 5-6 mm; it on the edge white and papilose. The entire gynostegium is 2.5 mm long; the corona scales have a length of 1. 5 mm; the absorbed appendage missing just as much in radial direction. The raised chisels are 1 mm long; the stigma head 0. 5 mm high. Kaiser Wilhelmsland: Eastern Mountains, in the high forest, 80 meters elevation (Lauterbach n.2041, blooming at on the l2th of May 1896); Nuru river, in the high forest 80 meters altitude (Delselbe n.2874; blooming on the 14th of September 1896). Comment: The species is distinguished through the very extended branches, whose inter nodes measure up to 20 cm.. The flowers are not, often, numerous nor crowded, because the stamens stand high up over the corona scales. Other literatrure: In Botanische Jahrbücher 50 (1913) 117. R. Schlechter. 18.

This species has a very distinctive leaf with venation similar to Hoya finlaysonii Wight with looping inner pairs anastomosing. The calyx scales, are broadly rounded with obtuse apices, ligules are present at their union. The crown is essentially horizontal but slopes outward slightly and is bind and acute at the outer apex. The scales are rather narrow, longitudinally ridged above and fully channeled below. The anther appendages slightly exceed the inner scale lobe. The staminal column is short to medium. This species has been compared to H. incrassata Warburg from which it differs in having leaves with acuminate leaf bases as opposed to H. incrassata's rounded to subcordate bases. It differs in the sepals not having cilia and its more narrowly elliptic corona lobes, with its longitudinal ridge extending from apex to apex, whereas H. incrassata ends at an umbo toward the inner lobe. Their outer lobe apexes differ also. I have retained Schlechter s area name of H. palawanica. Other literature: In The Asclepiadaceous Works of Friedrich Richard Rudolf Schlechter (1992) 31. A.
