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

Habit
Perennial, biennial or annual herbs.
Leaves
Leaves pinnately divided, usually with broad segments.
Inflorescences
Umbels compound; bracts 0; bracteoles several.
Calyx
Calyx teeth minute or obsolete, unequal.
Corolla
Petals white (sometimes flushed with pink, especially in bud), often markedly unequal and radiate, those on the outer margin of the umbel being much larger than those on the inside, the whole umbel therefore tending to function like a capitulum in attracting insects, although the individual flowers remain quite distinct.
Fruits
Fruit orbicular to broadly obovate, very strongly dorsally compressed, with a broad commissure. Marginal ridges expanded to form a broad wing, the dorsal ones filiform; wings somewhat thickened and closely appressed to those of the opposing mericarp.
Vittae
Vittae solitary in the intervals, clearly visible from the exterior, and tending to be club-shaped, narrowing towards the base, with 2 in the commissural face.
