The only kind, a fine shrub, from four to eight feet high, with smooth leaves, most of them with three lobes, and handsome cream-white flowers, tinged with pink on the outside and measuring two inches across.

There are a number of kinds of Sidalcea, difficult to distinguish; perennials; leaves round in general outline, variously cut and lobed; flowers showy, in terminal clusters; calyx with no outer bracts, or with only one; stamen-column double; stigmas threadlike, distinguishing them from Malvastrum and Sidalcea.
