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.
