Morphology
The outer surface of the inner perianth segments is conspicuously white because of a thick, felt-like layer of short hairs, easily to be seen in herbarium specimens. The base of the inner perianth segments is much narrower than the base of the filaments.
Most of the herbarium material is in flower, while fruit-bearing specimens are under-represented.
