''Sibbaldiopsis'' is a genus in the plant family Rosaceae containing the single species ''Sibbaldiopsis tridentata''. It was formerly a member of genus ''Potentilla''. Its common names include shrubby fivefingers and three-toothed cinquefoil. Systemic phylogenetic work has placed ''S. tridentata'' closer to ''Aphanes'' and ''Sibbaldia'' than to ''Potentilla''.(Erikkson et al. 2003) ''Sibbaldiopsis tridentata'' is commonly found in eastern Canada and parts of Greenland, south into the northeastern United States, with disjunct populations extending down the Appalachian Mountains. The southernmost known populations are located in Georgia and North Carolina, and occupy high-elevation rock outcrops and grassy balds.(USDA 2007) ''Sibbaldiopsis tridentata'' is a short (0.3–3 dm tall) woody perennial. It has leaves with 3 palmately arranged leaflets approximately 1–4 cm long which are toothed at the apex (typically three teeth). The leaves are retained in winter, but often with a red coloring. Flowers are small and white, radial, and arranged in a compound bracteate cyme. The individual flowers resemble flowers from the genus ''Potentilla''.(Radford et al. 1968) ''Sibbaldiopsis tridentata'' is listed as endangered in 5 US states.(USDA 2007) ==References== * * Radford AE, HE Ahles, and CR Bell. 1964 Manual of the vascular flora of the Carolinas.
