| Saxifragaceae | Astilbe biternata | Appalachian Astilbe, Appalachian False Goat's-beard | Cove forests, seepage slopes, boulderfield forests. | VA, sw. WV, and KY south to n. GA. |  |
| Saxifragaceae | Astilbe crenatiloba | Roan Mountain Astilbe, Roan Mountain False Goat's-beard | Mountain forests. | Known only from Roan Mountain, Carter County, TN and very rare or extinct. This species has apparently not been seen since the original collections (11 September 1885) by N.L. Britton and Mrs. Britton ("Tennessee. Base of Roan Mountain. Collected on the slope of Roan Mountain, East Tennessee, along the trail from ‘Cloudland’ to the Roan Mountain station of the E.T. & W.N.C.R.R."). The habitat, phenology, and other characteristics of this species are therefore poorly known. |
