Notes
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. Auderson did not attempt to establish any varieties. As to Nees' varieties, 1-flowered and 3-flowered cymes occur pretty frequently on one plant. B. barbata, Drège, is remote from B. obtusa, and is close to B. Gueinzii. But there is, in the Kew Herbarium, a branch of the large state of B. obtusa, issued by Drège as B. barbata, E. Meyer.
