Morphology General Habit
Climber, trailer or extensive liane 1–6 m. long; branches often reddish, striate, up to 5 mm. diameter, entirely glabrous or pubescent when young; rootstock up to 1.2 m. long, described in one note as rather like cassava, with red bark.
Morphology Leaves
Leaves simple, ovate to ± round, 5–20 cm. long, 5.5–16(–25) cm. wide, acute at the apex, cordate at the base, entire to shallowly to deeply 3–5-lobed, very variably serrate or crenate, the lobes sometimes ± lobed or pinnatifid, glabrous to pubescent or cottony or sometimes quite velvety beneath; petiole 3–13 cm. long; stipules oblong-triangular, 2–3 mm. long, 1.5–2 mm. wide, often expanded laterally.
Morphology Reproductive morphology Inflorescences
Inflorescences lax to dense, 5–10 cm. long, the ultimate cymes of flowers subcapitate; peduncle 2–6 cm. long, with tendril at or below the rhachis of the inflorescence; axes cottony or pubescent; pedicels 1–2 mm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx ± broadly cupular, 1.5–2 mm. wide, entire or shallowly lobed, glabrous.
Morphology Reproductive morphology Flowers Corolla
Petals green, pale yellow or reddish brown or in some areas bright red or maroon, oblong-ovate, 1.5 mm. long, glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens under 1(–1.5) mm. long.
Morphology Reproductive morphology Flowers Disc
Disk reddish, cupular, about 1/2 length of the glabrous ovary.
Morphology Reproductive morphology Fruits
Fruits red or reddish blue to purplish black, subglobose, ± 1 cm. in diameter; fruiting pedicels red.
Morphology Reproductive morphology Seeds
Seeds brown, depressed ellipsoid, 7–9 mm. long, 4–6 mm. wide, 2.5 mm. thick, shining, the groove not well marked but median ovate depression evident, median keel thick, irregularly rugose or outer annular part with 8–10 ridge-like or U-shaped rugae.
