Notes:
Rosa x involuta Sm. is a naturally occurring hybrid of Rosa spinosissima and Rosa sherardii. For many years it was thought to be Linnean species, but cytological evidence establishes that it was instead a hybrid of two species. Earlier references describe is as a hybrid of R. spinosissima x tomentosa.
A number of "varietes" of Rosa x involuta were named by Baker in the late 1800's, including var. gracilenscens (In Ireland), var. doniana, var. Mooorei, var. laevigata, var. occidentalis, var. Robertsoni, and var. wilsonii in Wales (see R. x involuta var. wilsonii in HMF). These distinctions may not survive modern scrutiny.
Rosa nivalis Donn (1815)
