Annual to subshrub, from taproot. Leaf: basal and cauline, alternate, simple, generally narrowly lanceolate or narrowly elliptic to ovate. Inflorescence: spike, nodding in bud, generally flower from basal-most to distal nodes. Flower: opening at dawn; sepals 4, reflexed singly or in fused pairs; petals 4, yellow, fading red, generally with 1+ red basal spots, with no ultraviolet pattern; stamens 8, longer opposite sepals, anthers attached at middle, pollen grains 3-angled except in polyploid taxa at 20×; ovary chambers 4, stigma ± spheric or hemispheric, exceeding anthers and cross-pollinated or ± = anthers and self-pollinated. Fruit: 4-angled at least when dry, generally proximally thick, contorted or curled 1–5 times, or straight, not swollen by seeds, sessile. Seed: in 1 row per chamber, narrowly obovoid, flattened, dull brown-black.
14 species: California, Arizona, Oregon, Baja California. (Greek: like Camissonia) [Wagner et al. 2007 Syst Bot Monogr 83:1–240] Polyploidy and self-pollination have predominated in evolution of genus. Incl in Camissonia in TJM (1993).
