Stem: spreading to erect. Leaf: 1.5–6 cm, linear to ± spoon-shaped, ± cylindric. Inflorescence: panicle of umbel-like clusters, compact; bracts scarious; pedicel 1–3 mm, straight in fruit. Flower: sepals 2–5 mm, glabrous, margins white-scarious; petals 3–5, 2–5 mm; stamens 5–7(10). Fruit: < calyx. Seed: 6–15, 1–2 mm wide, ± elliptic to ovate, smooth, shiny, black.
Desert scrub, sandy to silty soil, often alkaline; < 1000 m. Desert; southwestern Arizona, northwestern Mexico. [Calandrinia ambigua (S. Watson) Howell] Feb–May [Online Interchange]
Unabridged note: Belongs in neither Calandrinia nor Cistanthe, and might better be treated as a separate, monotypic genus, according to Hershovitz (pers. comm.). Expanded author citation: Cistanthe ambigua (S. Watson) Carolin ex Hershk.
