EUPHORBIA cameronii N. E. Br. [family EUPHORBIACEAE], (1911);. type: Somalia, data lost (see note) (K holo.).
Information
Densely branched glabrous shrub or small tree 2–8 m high; branches terete, fleshy, green, marked with prominent crescent-shaped leaf-scars. Leaves shortly petiolate, ovate, 2–4 x 1–2.5 cm with rounded apex, soon deciduous; petiole 2–4 mm long; stipules glandular, contiguous with a crowded row of small but conspicuous dark brown axillary glands, persistent after the leaf has fallen. Cymes terminal, in a 2–3-branched umbel or reduced to a solitary cyathium, on peduncles 2–5 mm long; bracts 2–3, conspicuous, transversely elliptic, 1–1.5 x 1.5–2.5 cm, white. Cyathia 7 mm in diam.; glands 5, 3–3.5 mm broad, green becoming yellow. Stamens well exserted. Perianth an obvious rim below the ovary. Styles 4.5 mm long, joined to halfway, with recurved thickened rugose apices. Capsule exserted on a recurved pedicel 10–13 mm long, subglobose, c. 1.5 cm in diam., obtusely 3-lobed, with 2 small fleshy ridges at the base of each lobe, pale green flushed with red. Seeds globose, 5–6 mm in diam., smooth, pale grey, minutely brown-speckled; caruncle 1.5–2 mm wide, yellow.

Notes
Ciin, mirhig (Som.). The data on the label attached to the type-specimen states: “British Central Africa [Malawi], 1905. Habitat Ntondwe. No. 153. K. J. Cameron, Esq.” As discussed by Bally in Candollea 18: 13 & 354 (1962–3), this label clearly does not belong to the specimen, the only one N. E. Brown saw. Prior to 1911, the date of publication of the species, this material was almost certainly collected inland from Berbera at the “Behindullah” locality in N1 (Bally 10400), and by either Mrs Lort Phillips, or – as Bally suggested – by Drake-Brockman.
