|discussion=<p>Sidalcea malachroides has long been considered to be the basal or so-called most ancient extant species of Sidalcea based on its morphology (E. M. F. Roush 1931; C. L. Hitchcock 1957). Molecular data support this conclusion (K. Andreasen and B. G. Baldwin 2001, 2003). These robust plants are distinguished by maplelike leaves that vary little in size and shape from base to apex of the stem, by relatively numerous, relatively small flowers with white or pale pink petals in dense, spiciform clusters on branched inflorescences, and by the coastal habitat. Formerly, it occurred in widely scattered sites from Monterey County, California, to Curry County, Oregon; fewer populations are extant; it has sometimes been cultivated. It is usually found in clearings and disturbed areas; it is threatened by logging and associated road usage, development, and non-native plant competition.</p>
