Taxonomy

A discussion of the typification of this widespread species can be found in Middleton (2000). As this species is so variable it is not easily delimited from its nearest relatives A. angustifolia, A. ganophylla and A. pilosa, all of which can also be quite variable. Specimens with the smallest flowers are found in northern Peninsular Malaysia and southern Thailand. Even greater variability in A. reinwardtii is found in continental Southeast Asia.
