North Carolina and n. South Carolina. |  (c) Cressler, Alan M. |
| Asaraceae | Hexastylis rollinsiae | Rollins's Heartleaf | Sandy mixed woodlands. | Native distribution speculative: Baldwin County, and perhaps also from Coffee County, Alabama. |  (c) Noah, Yawn |
| Asaraceae | Hexastylis rosei | Rose's Heartleaf | Moist acid forests under Rhododendron maximum. | Blue Ridge Escarpment, so far as is know endemic to Caldwell County, North Carolina. Two populations are now known (Schaner 2021). |  (c) Cressler, Alan M. |

| Asaraceae | Hexastylis shuttleworthii | Large-flower Heartleaf | Acidic soils in deciduous and deciduous-coniferous forests, often along creeks under Rhododendron maximum. | Endemic to the Southern Appalachians: W. North Carolina and e. Tennessee to nw. South Carolina, n. Georgia, and ne.
