Diagnostic Characteristics:
This species is known from upper elevations in the Cumberland Mountains. Primocanes (stems) are erect, not arching over to the ground and they do not root at the tips. Leaflets are glabrous with an obtuse to cordate base and with few prickles; the terminal leaflet of primocane leaves about half as wide as long.

Timber removal would be detrimental. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.
