Names
RHIGOZUM spinosum Burch. [family BIGNONIACEAE], MS.
Information
an erect shrub, 6–7 ft. high, with sinuous branches and spreading branchlets; spines 3–4 lin. long, inserted above the tomentose leaf-cushions; leaves simple or trifoliolate; petiole 1–1 1/2 lin. long; blade oblong, tapering towards the base, 3/4–1 1/2 in. long, 1 1/2–4 1/2 lin. broad, finely tomentose with stellate hairs when young, afterwards glabrous; flowers on lateral cushions; calyx broadly campanulate, nearly 4 lin. long, pubescent or finely tomentose; corolla yellow; limb 2 in. across; lobes suborbicular, 9 lin. in. diam.; filaments 4 lin. long; anthers under 1 1/2 lin. long, not beaked. null
Distribution
KALAHARI REGION Bechuanaland; on the rocks at the Chue Spring, Burchell, 2398/1!
Notes
Burchell's specimen has only one imperfect flower, of which enough remains, however, to show that R. spinosum is a very distinct species. In the Tropical African R. brevispinum, which has leaves of a similar shape, the flowers are only half the size and the calyx and adult leaves are covered with a very dense tomentum.
