Near B. Welwitschii, Reichenb. f., which it closely resembles in the 
flower, but in Welwitschii the lateral lobes of the lip are rounded and 
erenulate. The stem of В. acutiloba is somewhat slenderer and the leaves 
narrower and more sharply acuminate than in the Angolan species. The 
slit-like perforation in the middle line of the cymbiform base of the lip is an 
interesting character.
