Discusión taxonómica

Abutilon divaricatum var. hintonii Fryxell, Brittonia 32: 265 (1980) differs from var. divaricatum principally in lacking the long, somewhat retrorse hairs that are found on the stems, petioles, and pedicels of the nominate variety. It lacks the basal petal spot and also differs in geographical distribution.A
