Plagiobothrys bracteatus (Howell) I.M. Johnst.
Habit: Annual, sparse- to dense-strigose. Stem: generally ascending, occasionally decumbent, generally 1--4 dm. Leaf: basal lanceolate, hairs bulbous-based; lower cauline 3--10 cm. Inflorescence: bracts below middle. Flower: calyx 2--4 mm, strigose; corolla limb 1--3 mm diam, appendages pale yellow. Fruit: nutlet 1--1.8 mm, +- flat, lance-ovate, +- symmetric, +- dull; abaxial ridge short, near tip, lateral ridges +- arched, cross-ribs high, +- crowded, especially toward tip, interspaces narrow, tubercled, generally glabrous (bristly); margins with narrow border; adaxial ridge near middle, not folded to 1 side, not in trough; scar oblique, +- ovate to wide-triangular; +- sunken by surrounding ridge.
Ecology: Common. Vernal pools, wet places in grassland, coastal-sage scrub, chaparral; Elevation: < 2000 m. Bioregional Distribution: NW, CaR, SN (exc s SNH), ScV, n SnJV, CW, SCo, PR, MP, w DMoj; Distribution Outside California: southwestern Oregon, northwestern Mexico. Flowering Time: Apr--Jun
Synonyms: Plagiobothrys bracteatus var. aculeolatus (Piper) I.M. Johnst.
Unabridged Note: Highly variable; possibly the most common, widespread wetland member of genus western of Sierran-Cascade ridge at low to mid-elevations. If recognized taxonomically, plants with bristly nutlets in northern ScV assignable to Plagiobothrys bracteatus var. aculeolatus (Piper) I.M. Johnst., which has been confused with Plagiobothrys leptocladus. See note under Plagiobothrys cognatus.
