Decaisne indicates, however, Quipungo as the habitat, '' a locality on the West 

 Coast of Africa." Aschcrson, I.e., suggests that Kipungo in Mossamedes might 

 have been meant, and further that the Paris plant is identical with Welwitsch's 

 P. aurantiacus, which can hardly be the case judging from Gay's description.
