Slender, apparently erect, the branchlets somewhat zigzag, 1 
to 2 mm in diameter, pubescent with short spreading hairs. 
Leaves membranaceous, oblong to oblong-lanceolate, 8 to 15 cm 
long, 3 to 5 cm wide, mostly equilateral, base broadly rounded 
and prominently cordate, the sinus up to 1 cm wide and deep, 
rounded, narrowed upward to the acuminate apex, olivaceous and 
shining when dry, both surfaces sparingly pubescent on the mid- 
rib and nerves; basal nerves usually two pairs, not however 
sharply distinguished from the lateral nerves, all of the nerves 
rather slender, distinct, curved, anastomosing, up to 10 on each 
side of the midrib ; petioles 3 to 5 mm long, somewhat pubescent. 
Inflorescences axillary, about as long as the petioles, somewhat 
pubescent, few-flowered, but one flower developing at a time; 
bracts oblong to spatulate, 3 to 5 mm long. Flowers about 3 cm 
long, pubescent externally with scattered spreading hairs, the 
ovarian part of the tube about 4 mm long, the globose part about 
4 mm long, somewhat curved above the globose part, the tube 
about 10 mm long, the short lobe broadly ovate, rounded, about 
4 mm long, the long one about 15 mm in length, acute or acu- 
minate. Stamens apparently 8. Column with 6 flattened lobes. 
Capsule glabrous, obovoid, about 1 cm long. Seeds triangular 
in outline, 3 mm long, concavo-convex ; convex surface distinctly 
papillate.

This species is allied to Aristolochia sericea Blanco (A. imhri- 
cata Mast.) from which it is distinguished especially by its 
prominently cordate, thinner, less pubescent leaves, its much 
less pubescent flowers, and its glabrous capsules.
