Habit: Annual, from taproot; rosette generally +- 0. Leaf: cauline, alternate, simple, generally linear to narrowly elliptic. Inflorescence: bracted; spike or raceme, nodding in bud, erect in fruit, flowers only at distal nodes. Flower: radial, generally opening at dawn; sepals 4, reflexed singly or in pairs; petals 4, yellow, generally fading red, often with red basal spots; stamens 8, longer ones opposite sepals, anthers attached at middle, pollen grains 3-angled except in polyploid taxa, at 20×; ovary chambers 4, stigma hemispheric, generally > anthers and cross-pollinated, or +- = anthers and self-pollinated. Fruit: +- cylindric, straight to wavy, distorted by seeds at maturity, dehiscent throughout most of its length; pedicel +- 0 or <= 2(15) mm, 0 or shorter in flower. Seed: in 1 row per chamber, narrowly obovoid, smooth (minutely pitted), glossy.
Species In Genus: 12 species: western North America (especially CA-FP), 1 South America. Etymology: (L.A. von Chamisso, French-born German botanist, 1781--1838) Note: Polyploidy and self-pollination have predominated in evolution of genus. Not monophyletic as treated in TJM (1993); segregates moved to Camissoniopsis, Chylismia, Chylismiella, Eremothera, Eulobus, Neoholmgrenia, Taraxia, Tetrapteron (Wagner et al. 2007).
