Note. Brenan in FTEA distinguishes, in Kenya, ssp. beareana (Holmes) Brenan with spreading pubescence on the axils of the inflorescence, and petals 18-30 by 9-15mm: and ssp. kaessneri (Bak.f.) Brenan with appressed pubescence on the axils, and petals 15-20 by 7-10mm. Specimens occur in Kenya with these characters mixed (e.g. Mungai et al. 374/83, Green-way 9229, Heady 1248). But mostly the subspecies seem to be geographically separate, with ssp. beareana occuring at lower altitudes in Coast Province only.
