Euphorbiaceae, S. Carter & L.C. Leach. Flora Zambesiaca 9:5. 2001

Morphology General Habit
Glabrous perennial herb; rootstock woody, 1–2 cm thick, producing densely-tufted simple or sparsely-branched annual stems; stems erect, to 30 cm high, seldom more.
Morphology Leaves
Leaves densely crowded on the upper part of sterile growths, sparser and often shorter on flowering stems, sessile, spreading to reflexed; lamina to 30 × 5 mm, linear-lanceolate, rounded at the apex and conspicuously apiculate, cuneate at the base.
Morphology Reproductive morphology Inflorescences
Cymes occasionally axillary, usually clustered in terminal 3–7-branched pseudumbels with primary rays to 2 cm long, each forking usually once only or sometimes branching to produce further umbels.
Morphology Reproductive morphology Inflorescences Bracts
Bracts similar to the leaves, to 12 × 6 mm, and more ovate-lanceolate.
Morphology Reproductive morphology Inflorescences Cyathia
Cyathia usually subsessile, but sometimes on peduncles to 5 mm long, especially those at the centre of the umbels which sometimes develop only male flowers, c. 3 × 5 mm with broadly cup-shaped involucres, the central cyathia larger to 8 mm in diameter; glands 4–7 or occasionally more and sometimes proliferating amongst the male flowers to produce a "double" involucre, 1–2 × 1.5–3 mm, transversely oblong, margin very irregular, rounded, shortly 2-horned, or crenulate and convoluted, bright yellow; lobes 1–1.5 mm long, rounded, margin shallowly toothed, finely ciliate.
sex Male
Male flowers very many: bracteoles linear, ciliate at the apex; stamens 3.5–4.5 mm long.
Morphology Reproductive morphology Flowers
Female flower: styles 1.8 mm long, joined for one-third, with spreading thickened bifid apices. Male flowers very many: bracteoles linear, ciliate at the apex; stamens 3.5–4.5 mm long.
sex Female
Female flower: styles 1.8 mm long, joined for one-third, with spreading thickened bifid apices.
Morphology Reproductive morphology Fruits
Capsule exserted on a pedicel to 1.5 cm long, 5.5 × 6.5 mm, deeply 3-lobed, surface roughened.
Morphology Reproductive morphology Seeds
Seeds 3.5 × 3 mm, ovoid and slightly compressed, smooth, blackish with faint brown speckles; caruncle 1.5 mm across, wrinkled, orange.
