Taxonomic notes: While the flowers of this species are very constant in their overall morphology there is variation in the number of the stamens. On the basis of this variation 2 varieties have been described, one (var. icosandra) is disjunct and is found in W.Aust. only. The other var, pentamera was described from KI with its distinguishing character being its supposedly constant 5 stamens. Stamen number on specimens from KI varies from 5 to 10, and also varies in different flowers from a single specimen e.g. from 5 to 8. It is probable that detailed study would lead to the description of varieties of B. crassifolia based on the different leaf forms however, as the types of the type variety and var. pentamera have very similar leaves, it cannot be considered a good variety.
