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 papulosis, 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.
