Slender, climbing, perennial vine 1-7 m long or more, sparsely to densely
pubescent with unicellular curved trichomes on petiole, leaf, stem, and stipule,
0.20-0.30(-0.7) mm long, 0.02-0.03 mm wide, also minutely antrorsely
appressed-puberulent throughout with unicellular, curved trichomes, 0.06-0.11
mm long, 0.02-0.03 mm wide. Flowering stems terete or somewhat compressed,
0.6-1.6(-2.5) mm in diameter, greenish yellow to very dark reddish purple, with

0.3-1.8(-2.9) cm long, with 2 (rarely 1), opposite to alternate, stipitate or
sometimes sessile, slightly obconical to capitate nectaries (very rarely
crateriform), 0.3-0.8 mm wide (on the widest axis), 0.2-1.1 mm high, borne in the
distal half of the petiole (0.49-0.92 of the distance from the base toward the apex
of the petiole). Laminas 1.8-8.8(-12.0) cm long, (0.3-)1.4-8.2(-10.6) cm wide,
