[C] Note. Although mistaken in South Africa for an allied species, this pretty bulb differs from all the other small-flowered species in the genus by its broad linear-lanceolate leaves, and the broadly elliptic or suborbicular perianth-lobes, which have suggested the specific name to me. In all the other species the perianth-lobes are oblong or elliptic-oblong. My description is compiled partly from the English description of Dr. Phillips and partly from a dried specimen.—N. E. Brown.
[D] Note.—As Dr. Phillips has compared this plant with S. Burmanni Sweet, I would like to point out that it is very doubtful if the S. Burmanni of the Flora Capensis and the specimens in Herbaria so named, really represent the plant figured by Burmann, upon which that species was founded. Burmann (Rar. Afr. Pl. p. 7, t. 31) represents a plant with stems about half as thick as those of S. rigidum, constricted into short globose joints, with crenate (not entire) leaves and small flowers, of which he does not state the colours. I am doubtful if this plant is at present correctly represented in Herbaria.
It may also be well to point out that although the authority for the genus Sarcocaulon and the species S. Burmanni and S. Heritieri are attributed to De Candolle in the Flora Capensis they should be credited to Sweet, since De Candolle described them both as species of Monsonia under the section Sarcocaulon, which Sweet rightly recognised as a distinct genus.
