Names
EUPHORBIA muricata Thunb. [family EUPHORBIACEAE], Prodr. 86 and Fl. Cap. ed. Schult. 405
Information
a much-branched leafless and spineless succulent shrub, 1 1/2–2 ft. high; only upper portions of three main branches or stems bearing a few lateral branches seen; branches more or less constricted or jointed at their origin, opposite or sometimes alternate (except at the inflorescence) from only one branch at each node being developed, diverging from the stem from which they arise at an angle of 20°–35°, terete or (when dried) sometimes very distinctly 6-angled, with concave sides between the angles, scabrous, especially on the older parts, with very small crowded laterally compressed tubercles or crenations, glabrous; leaves rudimentary and scale-like, opposite, sessile, about 1/2 lin. long, ovate or deltoid-ovate, acute or obtuse, recurved and concave-channelled at the apical part, dark brown, soon deciduous; cymes terminal, 1/2–1 1/2 in. in diam., consisting of 2 opposite diverging branchlets 1/2–1 in. long, each forking once or twice into shorter branchlets bearing 3 involucres, but flowers are wanting on the specimens and are not described by Thunberg; bracts scale-like, sessile, 1/4– 1/2 lin. long, very broadly ovate, acute to very obtuse, dark brown. null
Distribution
COAST REGION Van Rhynsdorp Div.; on hills at Atties, Pearson, 5459! Clanwilliam Div.; between the Olifants River and Bockland, Thunberg!
Notes
Boissier has erroneously considered this to be identical with two other species which he associated with it under E. brachiata, E. Meyer, and states that the scabrous epidermis is only due to shrinkage in drying. This, however, is not the case, for the thin laterally compressed and somewhat minute tubercles are evidently structural, and neither they nor the angles and grooves present on the stem and branches of E. muricata are to be found upon any dried specimens of E. brachiata, E. Meyer, or any other South African species living or dried that I have seen. Besides the nature of its scabrous stems, this species is readily distinguished from the true E. brachiata, E. Meyer, by the often alternate and very much less divergent branches and different inflorescence, probably the involucres will also be found to differ. Thunberg's type consists of two small branches and Pearson's specimen of one branch only; the latter is identical with the type except that the stem shows only a slight trace of the six angles which are conspicuous on that of Thunberg.
