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.

Clarkia davyi is ecologically restricted, mainly growing along the Pacific coast on bluffs and grassy stabilized sand dunes, rarely farther inland. Its range extends from Humboldt and (barely) Del Norte counties in the north through all coastal counties to Santa Barbara County in the south, including Santa Rosa Island.

Clarkia davyi is morphologically similar to the polytypic South American tetraploid C. tenella and appears to be one of the parental species of the hexaploid C. prostrata.
