Information
Arborescent, succulent, spiny.Branches of the dried specimens seen 7-angled and about 4 1/2 in. in diam., with the solid central part about 1–1 1/4 in. thick and much less in diam. than the angles are broad (seedling plant 3-angled and 1–1 1/4 in. in diam.); angles wing-like, 2 in. broad and 2 lin. thick at the edge in the dried specimen, with triangular channels 1 3/4 in. deep between them. Leaves not seen. Spines 1 1/2–5 lin. long, in pairs, diverging, stout at the base, blackish-grey on the seedling, becoming grey with darker tips with age, on suborbicular horny shields 3–4 lin. in diam. on the mature branch, much smaller on the seedling, not connected by a horny border along the angles, becoming grey with age, with the flowering-eye touching or subincluded in their apical part. Cymes (detached, but distributed with the stem-sections) on peduncles 1/4– 1/3 in. long, bearing 3 involucres, the middle one sessile and the two lateral on cyme-branches 1 lin. long, glabrous. Bracts thin, adpressed, broken, but apparently suborbicular and about 3 lin. long and 2 1/2–3 1/2 lin. broad, very concave. Involucres 1/4– 1/3 in. in diam., cup-shaped, golden-yellow (Schweinfurth), with 5–8 glands and 5–8 transversely rectangular fringed lobes, glabrous; glands 1 1/2–2 lin. in their greater diam., erect in dried flowers, transverse, reniform, with the middle of the inner margin turned in and forming a small lip, or crescent-shaped, with the inner margin concave, in dried specimens with the outer margin more or less incurved. Ovary subsessile and included when young, in fruit exserted and curved to one side on a short stout pedicel, glabrous; perianth fleshy, with 3 lobes 2–2 1/2 lin. long, deeply cut into 2 or more filiform segments or entire and subulate-acuminate, in fruit reflexed and the segments often broken off; styles 1 3/4–2 lin. long, shortly united at the base, rather stout, slightly thickened and minutely 2-lobed at the apex. Capsule 5–6 lin. long and 8–10 lin. in diam., deeply 3-lobed as seen from above (globose-triangular and reddish when alive, Schweinfurth), glabrous; cell-walls very thick and woody. Seeds slightly compressed-subglobose, 1 3/4–2 lin. in diam., with a slight furrow on one side, smooth, light grey or whitish, slightly marbled, with a dull surface.
