Names
EUPHORBIA consobrina N. E. Br. [family EUPHORBIACEAE], (1911).
Information
Densely branched shrub 30–100 cm high, occasionally subscandent to 2 m high; ultimate branchlets 2–4 cm long, succulent, 2–5 mm thick marked with fairly prominent brown callose leaf-scars, greyish green and often purple-blotched. Leaves sessile, lanceolate to linear-lanceolate, 5–35 x 2–5 mm; stipules absent. Cymes in terminal 2–5-branched umbels, with rays 3–6 mm long surrounding a central sessile cyathium which usually develops only male flowers; bracts sessile, ovate, 3.5 x 3 mm, usually persistent until capsule development. Cyathia 6.5 mm in diam.; glands 4, or 5 on the central cyathium, separate, 2.5 mm broad, yellow becoming red. Ovary glabrous; styles 2.5 mm long, joined at the base, with shortly bifid apices. Capsule exserted on a slightly recurved pedicel 3–6 mm long, distinctly 3-lobed, 4.5 x 5.5 mm. Seeds ovoid, 2.75 x 2 mm, minutely tuberculate, yellowish brown; caruncle 0.5 mm across.

Notes
Ciin, enjir ad, ergin (Som.). Bally 11048; Lavranos & Carter & al. 24971; Kasmi, Mohamed & Hussein 5539. Variable in Somalia, and the name is applied here with reservation. Plants from the northeast mountain ranges have a similar erect habit, to 1 m high, as those from the type-locality in the Red Sea Hills (Sudan), but further south, at lower altitudes, habit becomes more straggly to almost subscandent. Characteristic features of the species are retained throughout this distribution, such as small cyathia, small distinctly lobed capsules and minutely tuberculate seeds. However, in Somalia, one significant characteristic of the species – persistent involucral bracts – is scarcely evident, such that a distinct taxon (or taxa) may be involved. Field study is required before this can be resolved.
