This species is well-defined by the loose cymes, and narrowly oblong obtuse 
posticous sepal, The variability in habit and size of leaves is very great, but 
T. Anderson did not attempt to estublish any varieties. As to Nees’ varieties, 
1-flowered and 3-flowered cymes occur pretty frequently on one plant. B. barbata, 
Drége, is remote from B. obtusa, and is close to B. Gueinzit. But there is, in the 
Kew Herbarium, a branch of the large state of B. obtusa, issued by Drége 
as B, barbata, E. Meyer. 
21. B. meyeriana (Nees in DC. Prod. xi. 230); stems 1-2 ft. long,
