petiole to 5 mm;
blade linear to narrowly lanceolate, 1–6 cm.
open racemes, axis recurved at tip in bud;
buds pendent.
axis recurved or erect;
buds pendent or erect.
floral tube 2–7 mm, with ring of hairs proximal to distal margin inside;

ovary 4- or 8-grooved or ribbed, or smooth (C. heterandra).
20–50 mm, beak 3–5 mm.
narrowly cylindrical or subfusiform, or rarely broadly subclavate (indehiscent, nutlike capsule in C. heterandra), 4 or 8-grooved or smooth;

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.

Species 15 (15 in the flora).
Section Phaeostoma is the largest section in Clarkia, with the 15 species classified in seven subsections. For the most part, these correspond with groups delineated originally by H. Lewis and M. E. Lewis (1955). Within the part of the genus with dimorphic stamens (8 in 2 dissimilar sets that vary in size and color), the species of sect. Phaeostoma have entire petals that taper to a distinct claw. Even though molecular support for sect. Phaeostoma is not strong (R. A. Levin et al. 2004), at this time it seems preferable to stress similarities and maintain this variable group in one section.
