Belongs within: Rosoideae.
Contains: Sanguisorbeae, Fragariinae, Potentilla.
Roperculina is a clade within the Rosaceae supported by molecular data and the presence of operculate pollen (Eriksson et al. 2003). It was defined by Eriksson et al. (2003) as “the least-inclusive clade containing Rosa cinnamomea, Sanguisorba officinalis, Fragaria vesca, and Potentilla reptans“. Rosa, the roses, is a Holarctic genus of shrubs and climbers, many species of which have become widely grown as ornamental plants. Its sister clade, Sanpotina, is well supported by molecular data but lacks distinct morphological synamorphies, though its members are marked by a reduction in the number of stamen whorls from many to three or fewer (Eriksson et al. 2003).
