Description

Sidalcea malviflora is a species of flowering plant in the mallow family, known by the common names dwarf checkerbloom, Greek mallow, prairie mallow and dwarf checkermallow. Sidalcea malviflora is native to the West Coast of the United States, from Washington to California, and into northwestern Baja California. It is a common plant of chaparral, coastal sage scrub, and other habitat types. Sidalcea malviflora is somewhat variable in appearance and there are many subspecies. In general it is a perennial herb growing from a woody caudex and rhizome, its stem reaching about 60 centimeters in maximum height. It is sparsely to densely hairy in texture. The leaf blades are variable in shape, but are often divided deeply into several lobes. The inflorescence is a dense or loose array of several flowers. The flower has five petals in shades of bright to dark pink, often with white veining, and measuring one to over three centimeters in length. Sidalcea is a genus (approx. 25 species) of the botanical family Malvaceae. It contains several species of flowering plants known generally as checkerblooms or checkermallows, or prairie mallows in the United Kingdom. They can be annuals or perennials, some rhizomatous. They are native to West and Central North America. In mid- to late summer the clumps of toothed basal leaves produce erect flowering stems, with 5-petalled mallow-type flowers in terminal racemes, in shades of pink, white and purple. Sidalcea is generally diploid (2n = 20), but polyploidy (4n, 6n) also occurs. Annuality appears to have evolved multiple times (4+) within this genus, although an ancestral annual state with annual paraphyly is also possible. Further, evolution rates within annual Sidalcea lineages appear to be faster than those of perennial lineages, at least when examining nuclear ribosomal DNA (internal and external transcribed spacer regions).
