siccitate subflaccidis, nervis utrinque circiter 4, patulis, cum 

 reticulis laxis subperspicuis ; umbellis multifloris, floribus glabris, 

 circiter 1 cm diamjetro, corolla rotata, lobis rhomboideo-ovatis, 

 obtusis vel acutis, processibus turgidis, crustaceis, oblongo- 

 ovatis, acuminatis. 



An epiphytic vine, the branchlets sparingly pilose, soon becom- 

 ing glabrous. Leaves heart-shaped, apparently fleshy when 

 fresh, rather flaccid w^hen dry, 5 to 7 cm long, 4.5 to 5 cm wide, 

 pale when dry, glabrous or the younger ones slightly ciliate near 

 the basal margins, the base broadly rounded and distinctly cor- 

 date, the sinus acute, the basal lobes broadly rounded, the apex 

 shortly and sharply acuminate; petioles 5 to 7 mm long; lateral 

 nerves about 4 on each side of the midrib, somewhat spreading, 

 anastomosing, the reticulations lax and distinct on both surfaces. 

 Umbels many-flowered, the flowers yellowish-white, usually 5- 

 merous, rarely 4-merous, 10 to 11 mm in diameter, their pedicels 

 about 2 cm long, glabrous. Calyx-lobes triangular-ovate, acute 

 or obtuse, 1 mm long. Corolla rotate, the lobes rhomboid- 

 obovate, about 4 mm long, obtuse or somewhat acute, the tips 

 more or less inflexed. Lower lobe of the coronal processes 

 oblong-ovate, acuminate, turgid, somewhat crustaceous, the up- 

 per surface somewhat concave. Staminal column short, sessile.

 tree trunks at low altitudes. 



A species well characterized by its broadly ovate, rather prom- 

 inently cordate, shortly and sharply acuminate, conspicuously 

 and laxly reticulate leaves.

An epiphytic vine, glabrous except the sparingly pubescent 

 pedicels. Leaves fleshy when fresh, coriaceous when dry, ovate 

 to oblong-ovate, shining, 8 to 12 cm long, 4 to 7 cm wide, the 

 base broadly rounded, the apex slenderly and sharply acuminate, 

 the epidermis on both surfaces coarsely reticulate-wrinkled when 

 dry; petioles 1 to 2.5 cm long; lateral nerves about 4 on each
