nearly 3 in. long; lips 8-10 lin. long, “brown tinged with lilac” 
(Scott), the lower with some long white hairs, in small flowers the 
corolla-tube sometimes barely 2 lin. long, the lips 32 lin. long. 
Staminodes varying in size in proportion to the size of the corolla, 
sometimes very small. Capsule 5-7 lin. long, sparingly pilose.—

It appears that the flowers most remote from the main axis are smallest, and have 
the least capsule. On the specimen which served as a basis for the original description 
there is a difference of 2 lin. in dimension between the fruits near the top and the 
bottom of the inflorescence. .B. anomala appears to be a depauperate form, as are the 
specimens collected at Katunga.
