Notes
VARIATION. There is considerable variation within this species, particularly in leaf-shape, indentation, indumentum, length of pedicel and flower-size. The species described within this “ group ” (now reduced to synonymy) were differentiated from one another by characters which are not constant, e.g. some specimens from the interior (Bechuanaland, Amboland and Ngamiland) described under Pretrea eriocarpa Decne., appear to differ from the coastal forms in having shorter, broader, less deeply divided leaves; there are, however, intermediate forms, particularly from the Transvaal and Rhodesia, which have both leaf-forms. Other characters have been tried out but appear to vary independently, so that the species cannot be separated into clear-cut varieties. In view of this lack of correlation it has been decided to treat the whole as one variable species. The citation “ British East Africa: near Malindi, Allen 157,” in F.T.A. 4 (2): 566 is an error. C. E. F. Allen collected in Southern Rhodesia and his number-157 was collected there near Malindi (18° 45′ S., 27° 1′ E.) in November 1905.
