Descriptions

Ranunculaceae, E. Milne-Redhead & W. B. Turrill. Flora of Tropical East Africa. 1952

Morphology General Habit
A tall climbing shrubby plant; younger stems with short curved hairs but becoming glabrous or nearly so, longitudinally ribbed and furrowed.
Morphology Leaves
Leaves pinnate, with usually 5 leaflets, reduced in association with the inflorescences; leaflets ovate to broadly ovate in general outline, obliquely asymmetric with acuminate lobes with relatively few and large asymmetric (curved) acute teeth, slightly cordate to broadly cuneate, with scattered hairs on lower surface, upper surface nearly glabrous, well formed leaflets 7–12 cm. long and 5–10 cm. broad.
Morphology Reproductive morphology Inflorescences
Inflorescences many flowered; pedicels 1–5 cm. long; flower buds broadly ovoid.
Morphology Reproductive morphology Flowers Calyx
Sepals 1.2–1.8 cm. long, cream.
Note
It is possible that several specimens from the coastal region of Tanganyika should be placed in this species. We have, however, not seen material sufficiently well collected for definite determination.
Habitat
Climbing up trees in coastal evergreen bushland, below 250 m.
