Range
Also in Tropical Africa. This species occurs in Great Namaqualand, north of the Tropic and has been collected as far south as Rehoboth; it may therefore yet be met with in our Western Region.
Distribution
EASTERN REGION Natal; Tugela, Gerrard, 1460! Delagoa Bay; Ressano Garcia, 1000 ft., Schlechter, 11938!KALAHARI REGION Transvaal; Potgieters Rust, Miss Leendertz, 1428!
Notes
It is nearly allied to C. gratissimus, Burch., and may be only a luxuriant form of that plant, but can usually be readily distinguished by its larger leaves, dull on the upper surface, with distinctly stipitate basal glands at the apex of the petiole; also to C. subgratissimus, Prain, but is very readily distinguished therefrom by the glabrous upper surface of the leaves.
