Descriptions

Umbelliferae, J. F. M. Cannon. Flora Zambesiaca 4. 1978

Morphology General Habit
A very robust perennial herb 1–2 m. high, often glaucous and sometimes sub-shrubby.
Morphology Stem
Stems arising several together, relatively simple and unbranched, terete, rigid, solid and with distinct rather fine grooves, glabrous to slightly puberulous, often tinged purplish-brown.
Morphology Leaves
Leaves glabrous, 2-ternate to pinnate, the lateral leaflets consisting of 3–5 pinnules, while the central leaflets have 2–3 pairs of pinnules, with or without a terminal pinnule. Ultimate divisions 4–6·5 × 1–4 cm., broadly ovate or subrotund to narrowly elliptic, fleshy and somewhat coriaceous, entire with a short mucronate tip, or with the apex cleft into 3 or more teeth. Leaf bases sheathing and auriculate, rather membranous. Juvenile leaves deeply cut with narrow segments or large irregular teeth.
Morphology Reproductive morphology Inflorescences
Umbels with numerous ± regular rays 3–9 cm. long, finely and densely pubescent.
Morphology Reproductive morphology Inflorescences Bracts
Bracts 1–4 × up to 7 mm., very well developed, linear, green with a membranous margin.
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles similar to the bracts, sometimes withering and partially eroded in mature fruiting umbels.
Morphology Reproductive morphology Flowers
Flowers numerous in each partial umbel on finely pubescent, regular rays; petals greenish-white to creamy-yellow.
Morphology Reproductive morphology Fruits
Fruit narrowly elliptic with well-developed, obtuse ribs, densely bristly pubescent, especially before maturity.
Morphology Reproductive morphology Flowers Gynoecium Stylopodium
Stylopodium conical; styles clubbed at the apex, reflexed in fruit.
Morphology Reproductive morphology Seeds Endosperm
Endosperm semi-circular in section, with blunt projections towards the broad ribs, commissural face flat.
Morphology Reproductive morphology Fruits Vittae
Vittae 1 in each interval and 2 in the commissural face.
Morphology Reproductive morphology Flowers Carpophore
Carpophore entire or 2-cleft nearly to the base.
