Morphology General Habit
Perennial herb, 0.5–2 m., with an underground creeping rootstock, sparingly branched above.
Morphology Stem
Stem ± terete, hollow, striate, generally ± multicellular-pilose above the base and increasingly glabrous upwards, sometimes glabrous almost throughout.
Morphology Leaves
Basal leaves long-petiolate (petiole ± 8–16 cm.), pinnate with 1–3 pairs of pinnae or usually subbipinnate with the lower pinnae again divided; pinnae and lower pairs of leaflets distinctly petiolulate; leaflets broadly ovate to elliptic, the terminal often but not invariably the largest, ± 3–9 × 2.2–5 cm., regular or more irregularly and jaggedly toothed, frequently (especially in the north and west of the range), bi- or tridentate, acute or acuminate, cuneate to subcordate at the base, ± multicellular-pilose; sheaths short and broad, striate; lower stem leaves usually similar but less divided, more shortly petiolate; median leaves deeply dissected, ± regularly dentate, the terminal leaflet frequently long, ± 3–8 × 0.4–1.4 mm., often but not invariably recalling a Cannabis leaflet, sheaths longer and narrower; uppermost leaves rapidly diminishing and often entire, trisect or linear and bract-like.
Morphology Reproductive morphology Inflorescences
Umbels numerous, on divergent glabrous peduncles 2.2–7 cm. long; rays 3–5, glabrous (extremely rarely with a few minute papillate hairs), 1.5–4 cm.; involucre absent; flowers (2–)3–5(–7) in each partial umbel, all hermaphrodite and producing fruit or occasionally a few abortive and ?, on glabrous 6–20 mm. pedicels; involucel absent.
Morphology Reproductive morphology Flowers Calyx
Calyx obsolete.
Morphology Reproductive morphology Flowers Corolla
Petals ± 1 mm., white to greenish white.
Morphology Reproductive morphology Fruits
Fruit ovate, 3–5.5 × 1.5–3 mm., laterally compressed, glabrous even when young, blackish when ripe with greenish ribs, calyx totally obsolete; stylopodia long-conical to narrowly elliptic, equalling or slightly longer or shorter than the recurved styles.
Habitat
Always in montane forest, or in rank vegetation where forest has been cleared, commonly in dense shade or along streams, also damp tracksides and forest margins; both Podocarpus-Hagenia and bamboo forests have been noted; 1360–3000 m.
Distribution
widespread from N. Nigeria and Cameroon to Ethiopia, Zaire, Rwanda and Burundi K3 K4 K5 T2 T7 U2 U3
