Rosaceae
A monotypic genus of the sub-family Rosoideae, allied to Cowania, from which it differs in the larger flowers, an inch or more across; in the more numerous pistils (up to twelve only in Cowania); and in having a whorl of bractlets at the base of the flower, alternating with the sepals.
Some names used by Bean have now been superseded and are no longer familiar. To ensure that all plants can be easily found, under any name, we have cross-referenced to The Plant List, a collaboration between RBG Kew, Missouri Botanical Gardens and other organisations, which aims to provide a currently accepted name for any plant. Not all taxonomists will agree with all Plant List nomenclature, but it provides a baseline to compare names. For each species above, clicking on the Modern Name will link to the entry for that name on The Plant List website.
