Kower Cruinea. Princes Island, Barter, 1981 ! Monteiro ! Henriques ! 

 A very distinct species. The lip of the only flower seen is somewhat broken in 

 front, so that its exact shape cannot be made out.

The following may also belong to this species : Mombasa, WaJcefield (a drawing) ! 

 between Kilimanjaro and the coast, frequent amonjj trees on the margins of maritime 

 creeks, Johnston I Giryama and Shimba Mts., near Mombasa, Taylor ! and Samburu, 

 Scott-Elliot ! but the materials are hardly sufficient for certain determination. 



Remarkable for its leafless habit, and large white flowers.
