| Distribution | This taxon has been included within the very common (in our area) R. flagellaris. Weakley (2022) splits it out, and BONAP and some other references also consider it valid. Weakley's (2022) map shows it as "rare" and only known from the Mountains. However, as his map shows it in all three SC provinces, the VA Piedmont, the GA Piedmont, etc., it likely must occur in the NC Piedmont. Thus, the range is certainly poorly known in NC; sadly, SERNEC shows no specimens (yet).
"PA and IA, south to SC, AL, LA, and TX" (Weakley 2022). | |
| Abundance | Poorly known. Assumed to be rare -- all of Weakley's abundance codes in the Eastern states are "rare", with his "common" codes being in LA, TX, and OK. Thus, one might wonder if occurrences in the Eastern states are truly native. | |
| Habitat | "Forests, woodlands, open areas, disturbed areas" (Weakley 2022). Wikipedia says "typically inhabits areas of rocky soil and partial shade, such as open woodlands and abandoned fields". Sadly, this broad collection of habitat types is so general/generic that it is unhelpful in a search for this species. | |
| Phenology | Flowers and fruits from April into June. | |
| Identification | This is a trailing species, like R. flagellaris, but in this scarce species the undersides of the leaves are densely hairy and soft to the touch. The leaf undersides of R. flagellaris are thinly hairy and not soft to the touch. | |
| Taxonomic Comments | See above. Considered by some as a valid species, but others have it subsumed within R. flagellaris.
