Discussion | Subspecies 2 (2 in the flora). As defined by Davis, the subspecies of Clarkia cylindrica have distinct but partly overlapping geographical ranges; subsp. cylindrica mainly in the South Coast and Transverse Ranges to the Tehachapi Mountain area, and subsp. clavicarpa mainly in the central and southern Sierra Nevada Foothills to the Tehachapi Mountain area. More recent collections suggest more substantial geographical overlap. Morphological variation correlates with geographical distribution, with the most consistent difference in ovary and capsule shape. According to Davis, the taxa are moderately interfertile, less so for more distantly separated individuals. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Clarkia prostrata, like C. davyi, occurs only on coastal bluffs and adjacent low elevation pine forests along the Pacific coast, and in this case only in the California Central Coast Subregion in Monterey, Santa Barbara, Santa Cruz, and San Luis Obispo counties. Clarkia prostrata is a hexaploid that combines the tetraploid genome of C. davyi and the diploid genome of C. speciosa. Clarkia prostrata is morphologically and ecologically very similar to C. davyi but can usually be distinguished by its larger flowers with a spot on each petal. It differs from C. speciosa by having smaller flowers with the stigma not exserted beyond the anthers. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
