Discussion
Condalia hookeri var. edwardsiana was noted by M. C. Johnston (1962) to be known only from a single thicket at the type locality in Edwards County, Texas; it was described as differing from the typical variety in its leaf blades being 2.5–3 times longer than wide (versus 1–2.5 times longer than wide). This morph has never been relocated despite repeated searching and appears to represent a populational variant. In the flora area, C. hookeri is widespread in central and southern Texas.
