Notes
The plant figured and described by Alpino has been erroneously referred to this species by Schultes, and has been misunderstood by all authors. Alpino's figure is undoubtedly a representation of Leptadenia heterophylla, Decne, a well-known inhabitant of Upper Egypt and the Nile Region, whilst the description of S. Alpini given by Schultes, so unmistakably refers to this South African plant, that it evidently was made entirely from it. The var. retusa (E. Meyer, l.c.), founded upon Drège, 3474, with obtuse or slightly retuse leaves, is a common form not worth varietal distinction. The follicles distributed with Miss Pegler's 662 are much longer (5–6 in. long) and more slender (1 lin. thick) than in any other specimen seen, but I find no difference in the flowers.
