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 lassenensis is found primarily in the northeastern counties of California, south-central counties of Oregon, and northwestern counties of Nevada, with a few outlier collections from Alpine and Placer counties in the Sierra Nevada, and from northern Mendocino and Glenn counties in the North Coast Ranges.

Clarkia lassenensis is morphologically most similar to C. arcuata and C. gracilis. At one time, C. lassenensis was considered a probable parent of the tetraploid C. gracilis but cytogenetic and molecular sequence data indicate that an unknown related species, presumably now extinct, was involved. Clarkia lassenensis can be distinguished readily from C. arcuata by flower size, position of the stigma, and pubescence of the immature capsule, and from C. gracilis by having immature capsules with eight grooves rather than four.
