Morphology General Habit
Liana climbing to 3 m. or perhaps more.

Leaves:stipules fused for at least 2/3 of the length, 0.5–1 cm. long, densely pubescent outside, glabrous inside; petiole 2.5–11.5 cm. long, usually pubescent and densely covered by protuberances with stinging hairs; lamina herbaceous, dark green, often drying almost black, with paler underside because of dense indumentum, ovate to elliptic, 7.5–15 cm. long, 5–10.5 cm. wide, base cordate to subcordate or truncate, margin serrate with 25–35 teeth on each side, apex bluntly acute to acuminate; lateral nerves 4–5 pairs, basal pair extending into upper 1/2–1/3; upper surface subscabrous to smooth, glabrous or with a few short, stiff hairs, cystoliths punctiform, rarely somewhat elongated, lower surface with stinging hairs on the nerves and usually densely white-felted between the nerves or on the fine reticulation of the ultimate nerves.
Morphology Reproductive morphology Inflorescences

sex Male
Male flowers on pedicels 1–1.5 mm. long, articulated below perianth, 5-merous, perianth ± 1 mm. in diameter.
Morphology Reproductive morphology Flowers
Female flowers sessile; perianth tubular, with 4 teeth at apex; ovary enclosed except for penicillate stigma. Male flowers on pedicels 1–1.5 mm. long, articulated below perianth, 5-merous, perianth ± 1 mm. in diameter.
sex Female
Female flowers sessile; perianth tubular, with 4 teeth at apex; ovary enclosed except for penicillate stigma.
