Note
D. penninervium seems to have a fairly restricted distribution in Kenya though it is often common in the habitats in which it is found. It is more widely distributed in Tanzania and is particularly well-distributed within Ethiopia. Bitter (1920) distinguished several varieties of this species on minor variations in leaf pubescence. These variations are all considered to be within the limits acceptable in D. penninervium, and these varieties have all therefore been provisionally syonymised with this species. Most of the type specimens cited by Bitter were lost in the bombing of the Berlin herbarium. Only one duplicate has so far been traced, and this specimen ( Scott Elliott 7714) has been selected as the lectotype of D. penninervium Hochst. var. nervisquum Bitter. Some of the Ethiopian isotype specimens of this species ( Schimper 917) exhibit the glabrous styles typical of D. eremanthum, while others are sparsely pilose. A number of specimens collected in T 2 (e.g. Arusha District: SW Meru & Ngurdoto Crater; Masai District: Empakaai Crater, Ngorongoro Conservation area; cf: Frame 59; Greenway & Kanuri 11987; Haarer 1168; Richards 24652) also have glabrous or glabrescent styles. However, with one exception ( Mooney 7011 collected from Shoa, Wofasha Forest), all other Ethiopian specimens so far examined have pilose styles.
