Morphology General Habit
Liane growing into the tree tops or a tree to 16 m. tall, woody shrub or low straggling tree.
Morphology Leaves
Petioles up to 22 cm. long by 6 mm. diameter, glabrous; leaflets (4–)5–7(–8), coriaceous, narrowly elliptic to rotund, lanceolate to ovate or oblanceolate to narrowly obovate, sometimes somewhat oblong, up to 28 cm. long by 12.5 cm. wide, mucronate to long-acuminate, rounded to broadly cuneate, often subcordate, occasionally ± truncate at the base, with subentire to repand, sometimes very slightly crisped margins, thickened or unthickened at extreme periphery, glabrous, with many very closely spaced parallel lateral veins; petiolules 1.0–8.5 cm. long by 1–3 mm. diameter.
Morphology Leaves Stipules
Stipules up to (and probably exceeding) 4.5 cm. long, adnate to petiole for up to 1.5 cm.
Morphology Reproductive morphology Inflorescences
Inflorescence (fig. 5/9) a group of up to about 6 primary branches (panicles of umbellules) 2.5–14.0(–18.0) cm. long, each typically with a racemose arrangement of secondary branches for some distance and an aggregation (umbel) at the apex; secondary branches (0.8–)2.0–7.0 cm. long with tertiary branches (peduncles of umbellules) aggregated at their ends (occasionally also with a few scattered along their length); peduncles of umbellules 0.75–3.2 cm. long; pedicels up to 8(–11) mm. long, up to about 12 per peduncle; bracts inconsistently present with large variation in size in those subtending first and second order branches, those subtending tertiary branches or pedicels very small or obsolete.
Morphology Reproductive morphology Fruits
Fruits urceolate to subspherical, up to 4.5 mm. long by 5.0 mm. diameter, deeply sulcate when mature, glabrous or puberulous; stylopodium 0.5–2.0 mm. long; styles 5 (rarely 6), free for up to 1.2 mm. terminally.
