siccitate subflaccidis, nervis utrinque circiter 4, patulis, cum 
reticulis laxis subperspicuis ; umbellis multifioris, floribus glabris, 
circiter 1 cm diametro, 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 when 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 indexed. 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
