The placing of the above specimen is very unsatisfactory. It is admittedly difficult to distinguish it from the type of D. megalantha, although that has the petioles shorter, wider at the apex and more emarginate. It might be better to treat Milne-Redhead 1107 as a very narrow-petioled variant of D. pteropus resembling var. angustipetiolata Verdc. from western Tanzania. The Angolan material is not at all uniform, and until better understood I am content to follow Milne-Redhead and Torre in considering the single Zambian gathering to be a variant of D. megalantha since it differs from the type of the latter only in having longer petioles of more uniform width.
