attingentibus, reticulis laxis, distinctis ; petiolo crasso, 2 ad 5 cm 
longo; pedunculis 2 ad 5 cm longis, partibus superioribus in- 
crassatis, 3 ad 4 mm diametro ; floribus numerosis, flavidis, 7 
ad 8 mm diametro, petalis intus papillosis, rhomboideis, leviter 
acuminatis; coronae lobis patulis, oblongo-ovatis, acutis, subpla- 
nis, 2 mm longis. 
A scandent plant entirely glabrous except the papillose corolla 
lobes. Branches terete, brownish or grayish, smooth, up to 5 
mm in diameter, sometimes with roots along one side of the 
internodes, the internodes up to 12 cm in length. Leaves thickly 
coriaceous, pale and shining when dry, broadly ovate to elliptic, 
8 to 16 cm long, 6 to 9 cm wide, the apex broadly and rather 
prominently acuminate, base rounded, prominently 5-nerved, 
the interior pair of nerves reaching the apex, the reticula- 
tions very lax, distinct on both surfaces, the margins somewhat 
recurved; petioles stout, 2 to 5 cm long. Umbels axillary, soli- 
tary or fascicled many-flowered, about 4 cm in diameter, the 
peduncles 2 to 5 cm long, the thickened upper part of the rachis 
cylindric, 3 to 4 mm in diameter, marked with numerous scars, 
this rachis on older inflorescences up to 4 cm in length. Flowers 
yellowish, 7 to 8 mm in diameter, rotate, the buds prominently 
5-angled, 4 mm in diameter. Sepals membranaceous, oblong- 
ovate, somewhat acuminate, 1.5 mm long. Corolla distinctly 
papillate within, the lobes rhomboid, somewhat acuminate, about 
4 mm long and 3 mm wide. Staminal-column about 4 mm in 
diameter, the lobes spreading, oblong-ovate, acute, the upper 
surface nearly flat or slightly concave, the external apex not 
recurved, the internal one elevated, acute, short. Follicles about 
12 cm long.

The alliance of this species is manifestly with Hoya fischeriana Warb., 
to which it conforms closely in its floral characters. It is distinguished 
by its very differently shaped leaves.
