Notes
A specimen from the Entebbe Botanic Garden, collected on 2 May 1910 (Dawe 993) may have come from a wild plant. Oliv. (F.T.A. 1: 39 (1868)), describes a var. sempervirens based, according to Hiern (Cat. Afr. Pl. Welw. 1: 13 (1896)), on Weiwitsch 774; Hiern calls the typical variety var. decidua and cites Welwitsch 776 and he also describes a var. macrophylla based on Welwitsch 775. Welwitsch 774 and 775 are from Pungo Andongo whereas 776 is from Golungo Alto. They do not seem to be different entities. The specimen from T4 has white petals with green-spotted tips but appears to be this species.
