Notes
O. uhuhensis is in its more extreme forms very distinct from O.semiloba and at first sight it appears unnecessary to reduce them to subspecies. Where they overlap, however, as in Tanganyika and Mozambique there are transitional forms and both subspecies show much variation in the lobing of the leaflets. Kassner 2163 (BM) shows the transition from a very narrowly lobed leaflet to a form almost indistinguishable from subsp. semiloba while Torre 4892 from the Zambezia Prov. of Mozambique shows a series ranging from the broadest-lobed form of Kassner 2163 to quite typical subsp. semiloba. The great majority of the specimens fall clearly into one or other of the two subspecies but a few cannot be satisfactorily classified.
