Habitat:
In open grassland close to forest edge, 2490 m.,
Note:
Flowers rose coloured or pale pink, scentless.
A remarkable species whose nearest relatives are the two South African species mentioned in the diagnosis. The most striking feature is the lacerate or fimbriate margins of the petals and of the apex of the lip. The occurrence of a new species of this affinity so remote geographically from the two older species is particularly interesting, especially as neither of the southern species occurs in Natal or the Transvaal.
Distribution:
Sudan to E. Trop. Africa
