Hoya collina Schlechter 1913

Type description:

 

In Botanische Jahrbücher 50 (1913) 111.  R. Schlechter. 6. Hoya collina Schltr. n. sp.— Suffrutex epiphyticus, ramosus, scandens. Rami filiformes, flexuosi, bene foliati, teretes, glabris, Folia erectopatentia vel patula, breviter petiolata, elliptica vel obovato‑elliptica, obtusa, basi cuneata, carnosa, utrinque glabra, petiolo carnoso, superne leviter sulcato. Inflorescentia pedunculata, foliis fere aequilonga, umbelliformis, 6—12—flora, pedunculo pedicellisque glabris. Flores in sectione inter minores; illis H. eitapensis Schltr. similes, sed paulo majores. Calycis segmenta ovato‑triangula, obtusa, glabra, quam corolla multo breviora. Corolla rotata, usque infra medium 5-fida, extus glabra, intus brevissime et dense papillosa, lobis late ovatis obtusiusculis. Coronae foliola patentia, elliptica, antice subporrecta, obtusiuscule acuminata, extus obtusa superne longitudinaliter per medium leviter incrassata, lateribus rotundata, antheris vix breviora. Pollinia  oblique oblongoidea translatoribus subnullis, retinaculo rhomboideo, minuto.
Ein zierlicher Schlinger mit schnurförmigen, gut beblätterten Zweigen. Blatter 35 —5.5 cm lang, in der Mitte oder über der Mitte 1.8—2.7 cm breit. Blütenstande doldig, 6 - 12 blütig, auf etwa 4 cm langen,  kahlen Stielen. Blütenstiele sehr schlank, kahl. Ca. 1 cm lang. Bluten in der Sektion ziemlich klein. Kelchzipfel ca. 1.25 mm lang kahl. Korolla 0.8 cm im Durchmesser. Koronaschuppen von der vorderen Spitze bis zum äuszeren Rande ca.1.75 mm lang.
            Nordöstl. Neu-Guinea: an Badmen und auf Staüchern in den Walden der Hügel oberhalb des Kambaran, am Fusze des Finisterre‑Gebirges, ca. 400 m. u. M. Schlechter n. 18114..—Blühend im August 1908). Schon äuszerlich ist diese Art vor den beiden oben beschriebenen dadurch kenntlich, dasz ihre Zweige erheblich dicker und fleischiger und die Blatter gröszer sind. In der Blüten ist die Papillenbekleidung auf der inneren Seite der Korolla characteristisch und die Spitzen der koronaschuppen sind mehr wagerecht vorgestreckt. Die Färbung  der Bluten ist gelblich‑weisz.

In Hoyas of Northeastern New Guinea (1992) 23-24.  (Translation of the German). R. D. Kloppenburg.  Hoya collina Schlechter n. sp. - Epiphytic, twining perennial plant woody at base, branched. Branches thread like, flexible, well foliated, round, glabrous. Leaves erect spreading or widely outspread, shortly petioled, elliptic or ovate-elliptic, obtuse, wedge shaped base, fleshy, both sides glabrous, petiole fleshy, above lightly furrowed (grooved). Inflorescences pedunculate, leaves nearly equal (the same length) like an umbel, 6-12 flow­ered, pedicels of the peduncle glabrous. Flowers in this section among the smallest. Similar to H. eitapensis Schltr. but a little larger. Segments of the calyx ovate-triangular, obtuse, glabrous, much shorter than from the corolla. Corolla rotate, 5 parted to below the middle, inside shortly and densely papillose, lobes broadly ovate obtuse. Leaflets (scales) of the corona  spreading, elliptic, with the tip (apex) somewhat stretched outwards and forward, obtusely acuminate, outside obtuse above longitudinally slightly thickened through the middle, sides rounded, anther barely small (I assume small). Pollinia obliquely oblong, with the translators almost missing, retinaculum rhomboid, minute.
A pretty clinging vine with cord like, well leaved branches. Leaves 3.5-5.5 cm. long, in the middle or above the middle 1.8-2.7 cm. wide. Inflorescences umbel like., 6-12 flowered, on a bare peduncle, about 4 cm. long. Pedicles very slender, bare about 1 cm. long. Blooms in the Section rather small. Calyx about 1.25 mm long, bare. Corolla 0.8 cm. in diameter. Corona scales from the forward tip to the outer edges about 1.75 mm. long.
Northeastern New Guinea: on trees and upon shrubs in the forests of the hills above the Kambaran at the foot of the Finisterre Mountain range about 400 m. altitude (Schlechter #18114 - Bloom­ing in August 1908).
Externally this species is distinguishable from the two described above by the fact that its branches are thicker and fleshier and the leaves are larger. It is characteristic in the blooms and the papilla covering the inner side of the corolla and the tips of the corona scales are more horizontal. The color of the blooms are greenish white.
