Discussion | Clarkia epilobioides is known from south-central Arizona in Gila, Maricopa, Pima, and Pinal counties, and widely in west-central and southwestern California and adjacent Baja California, Mexico. In California, it occurs from Contra Costa and San Mateo counties in the San Francisco Bay area to San Diego County in the south, including most of the Channel Islands. Clarkia epilobioides is modally self-pollinating, and up to half of its flowers do not open, yet set a full complement of seeds (H. Lewis and M. E. Lewis 1955). However, outcrossing does occur, and C. epilobioides is one of the parents of the tetraploid species C. similis, from which it differs by having white, unflecked petals; it is also one of the parents of the tetraploid C. delicata.

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.) |
