Notes
When growing in rocky places, crevices etc. it can be much smaller e.g. Verdcourt 57 & 58 (Lushoto District, R. Dodwe by Amani to Monga road crossing, 23 Jan. 1950). Several varieties have been described from Asia including var. villosissima C. Chr. with varying degrees of indumentum but I have considered the East African material typical and am not sure of the validity of these varieties. The lectotype is rather sparsely pilose. Material I have seen from K 3 has been wrongly identified, and was not this species. The lowest altitude and K7 record are based on a sterile young specimen (Kwale District: Shimba Hills, Mwele-Mdogo, 12 Sept. 1997, Luke et al. 4724!)
