Notes
O. geminiflora is known only from two old South Africa specimens and a specimen from Rhodesia and these are more robust plants than the Tanzanian specimens, with longer coarser leaves. The true status of these specimens is doubtful—it could be looked on as a form of O. capensis with abnormally long sepals or a northern variant of O. geminiflora which is itself dubiously distinct. It is pointless to discuss this without much more material.
