Discussion

In the flora area, Allowissadula holosericea ranges from the Edwards Plateau to the trans-Pecos mountains and westward; in Mexico, it occurs north of the Sierra Madre Oriental and Sierra de Tamaulipas.

The name Abutilon velutinum A. Gray 1849 (not G. Don 1831), which pertains here, is illegitimate.
