Plagiobothrys cusickii (Greene) I.M. Johnst.
Habit: Annual, +- strigose. Stem: erect to occasionally prostrate, 0.5--3+ dm, +- branched above base. Leaf: cauline, lower 3--10 cm. Inflorescence: bracts below middle to throughout. Flower: calyx 1.5--4 mm, strigose; corolla limb 1--2 mm diam. Fruit: nutlet 1--1.6 mm, +- flat, ovate, asymmetric, shiny; abaxial ridge short, near tip, lateral ridges obscure, cross-ribs +- evenly spaced, rounded, interspaces +- tubercled (bristled or scabrous); adaxial ridge beyond middle, +- folded to 1 side below; scar near base, occasionally oblique, generally hollow, +- oblong, with thin, +- incurved margins, sunken.
Ecology: Wet, muddy areas, flats in sagebrush scrub, conifer forest; Elevation: (60)450--2100 m. Bioregional Distribution: s NCoRI, CaRH, n&c SNH, sw ScV, GB; Distribution Outside California: to eastern Washington, Idaho, Nevada. Flowering Time: May--Aug
Synonyms: Plagiobothrys scouleri (Hook. & Arn.) I.M. Johnst. var. cusickii (Greene) L.C. Higgins; Plagiobothrys scouleri var. penicillatus (Greene) Cronquist, in part
Unabridged Note: Evidently much less common than Plagiobothrys cognatus (see also note there) in MP, northern SNH, and than Plagiobothrys hispidulus in CaRH, SNH possibly due to more specialized habitat requirements. Collections western of the Sierran-Cascade, if verified, may indicate introductions there. Verified collections from ScV, NCoRI need study.
