Information
Annuals with spreading branches 20-40 mm long, but sometimes internodes not elongating and plant only 2-6 mm high, gla­brous. Leaves sessile to shortly petiolate; lamina rhombic to triangular or obovate, 2-4 x 2—4 mm, obtuse, abruptly constricted towards the base, covered with papillae on upper surface, dorsiventrally flattened and often convex above, green to reddish brown, petiole up to 2 mm long. Inflores­cence a thyrse often with only one dicha­sium, with 4-merous flowers sessile at first and pedicel elongating when fruiting. Calyx: lobes broadly oblong, 0,6-1 mm long, cov­ered with papillae towards apex, fleshy, green to brown. Corolla cup-shaped, scarce­ly fused basally, cream often tinged red; lobes ovate, rarely lanceolate, c. 1 mm long, bluntly acute, erect to somewhat recurved. Stamens with yellow anthers. Squamae nar­rowly oblong-cuneate, 0,3-0,4 x 0,1-0,2 mm, truncate or rounded, gradually constricted downwards, almost membra­nous, white. Seeds 6-8, released through ap­ical pore of follicles.
Habitat
Plants growing in exposed positions often form an almost flat disc rather reminiscent of C. pageae (no. 13), but ifconditions change subsequently, the younger internodes will elongate. It is interesting to note that the pedicel will elongate up to 15 mm even in depaupe­rate plants.
Use

Afr. 17: 190 (1929); Adamson in Adamson & Salter, Fl. Cape Penins. 432 (1950); Tolken in Contr. Bolus Herb. 8: 112 (1977). Type: without exact locality, Thunberg in Herb. Thunberg 7804 (UPS, holo.!).
Range
Found mainly in the south-western Cape Province from near Williston to the Cape Peninsula but mainly on the eastern side of the mountains where the distribu­tion area extends into the southern Great Karoo and the Little Karoo; often growing in great numbers in sandy soils or on gravelly slopes but rarely in shaded positions. Flowering period: July-October. Map 9.
