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. imbri- 

 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.
