Description

Sarcocaulon is a genus of succulent, spiny shrublets with short stems, branching just above soil level. The fleshy branches are prostrate, semi-erect or erect, covered with waxy, translucent bark.

Dimorphic (two forms) leaves characterise the genus, with the blades either long or shortly petioled. The long petioles occur singly and remain as blunt or sharp spines, and the short ones occur singly or in groups of 2-7 in the axils of the long spines as blunt stalks. The leaf blades are often folded, unsegmented or segmented, and vary in outline from elliptic to ovate to obovate (egg-shaped with the broadest part above) with the bases usually tapered. The tips are notched and the margins entire, lobed or toothed.

The flowers, subtended by 2 bracts, appear solitary in the axils of the leaves. They are pedunculate (stalked), 5-merous with the sepals of the calyx and the petals free. The margins of the sepals are membranous and the tips end abruptly in a short, stiff point. The thin, delicate petals are inversely egg-shaped (obovate) to almost squared off (subtruncate) at the tips and wedge-shaped at the bases, usually glabrous, sometimes covered with soft, short, erect hairs or fringed with hairs along the edge. Fifteen stamens, 5 with long filaments and 10 with shorter filaments, are characteristic of Sarcocaulon.

Members of the Geraniaceae family have a peculiar dry fruit with the carpels much elongated. At maturity only the inner parts of the united carpels remain as a central column, whereas the outer part of each carpel, enclosing one seed at the base, lifts off. In Sarcocaulon the seeds and the sterile upper part of the carpel become completely detached. The tail is thin, readily absorbs moisture (hygroscopic), and has long weak hairs (villous).
