| Fabaceae | Robinia hispida var. hispida | Common Bristly Locust | Woodlands and forests, and as an escape in disturbed areas and roadsides. | Probably originally endemic to the Southern Appalachians (and perhaps adjacent provinces) of NC, SC, GA, TN, and VA, now widely distributed in e. North America as an escape from cultivation. |  |
| Fabaceae | Robinia hispida var. kelseyi | Kelsey's Locust | Mountain woodlands, introduced elsewhere. | Traditionally considered an endemic originally restricted to w. NC, but Cronquist (1980) and Isely & Peabody (1984) suggest that var. kelseyi may have been only of horticultural origin. |  |
| Fabaceae | Robinia hispida var. rosea | Boynton's Locust | Pitch pine woodlands, other mountain woodlands. | Originally distributed from se. KY, s. VA, and e. TN south to nw. SC, n. GA, and ne. AL, now occasionally found outside that range as an escape from cultivation. |  |
