Vascular plants of NE US and adjacent Canada
Hypanthium globose to urceolate, with a constricted orifice; sep usually long-attenuate or prolonged into a foliaceous tip, often persistent in fr; pet large, spreading at anthesis, pink to red, white, or yellow; stamens very numerous, inserted near the orifice of the hypanthium on relatively short filaments; ovaries mostly numerous, inserted on the bottom or also on the sides of the hypanthium; styles usually barely exserted, distinct or ±united; fr a bony achene; mature hypanthium, called a hip, commonly colored and pulpy or fleshy; shrubs or woody vines, usually prickly; lvs pinnately compound with 3-11 serrate lfls, the stipules commonly large and adnate to the petiole; x=7. Genus beset with hybridization and polyploidy. 100+, mainly N. Temp. The application of the names R. spinosissima and R. cinnamomea is now so confused that both have been abandoned in Flora Europaea. We do likewise.
