Euphorbia reinhardtii

A tree 40–50 ft. high, with a trunk 12–15 in. thick, branching about 10 ft. from the ground into a dense obconic flat-topped crown of succulent spiny leafless branches, glabrous. Branches constricted into segments 8–12 in. long, with the terminal or flowering segments broadest at the base, tapering upwards or conical in general outline, 3–5- (usually 4-) angled, with the central solid part 1 1/4–1 2/3 in. square and the angles wing-like and 1–1 1/3 in. broad. Spines up to 5 lin. long, stout and about 1/8 in. thick at the base, in pairs 3/4–1 1/3 in. apart, diverging, those on the flowering segments gradually smaller and often disappearing. Flowering-eyes placed a little above the spine-pairs. Involucres 4–9 in a cluster (really composed of 2–3 subsessile or sessile cymes), sessile or very shortly pedunculate, about 1/4 in. in diam. and about as deep, fleshy, tubular-campanulate, slightly constricted at the middle, with 5 glands and 5 fringed lobes; glands distant, about 1/8 in. in their greater diam., transversely elliptic, entire, with the inner margin incurved. Capsule as large as a cherry, depressed-globose, not 3-angled or lobed, red; styles bifid at the apex.
