Annual to perennial herb; generally fleshy. Stem: 1–many, generally glabrous. Leaf: simple, alternate or opposite. Inflorescence: axillary or terminal; cyme, raceme, panicle, umbel, or flower 1. Flower: bisexual, radial; sepals generally 2(9), free; petals (1)2–19, free or ± fused; stamens 1–many, epipetalous or not, anthers pink, rose, or yellow; ovary superior, chamber 1, ovules 1–many, placenta basal or free-central; styles (0)1–8, generally fused at base, branched. Fruit: capsule, circumscissile or 2–3-valved. Seed: 1–many, shiny or ± pebbly or sculptured, black or gray, generally with oil-filled appendage as food for ants.
± 22 genera, ± 230 species: generally temperate America, Asia, Australia, Europe, Kerguelen Is, New Zealand, southern Africa, poorly represented in Europe; some cultivated (Lewisia, Calandrinia).

Key to Montiaceae
Annual, perennial herb, from stolon, rhizome, tuberous root, or taproot, glabrous, ± fleshy. Leaf: entire; basal generally 0–many, rosetted; cauline generally 2, ± opposite, free, ± fused on 1 side, or fused into ± disk. Inflorescence: terminal, raceme, 1-sided; pedicel reflexed, in fruit erect. Flower: petals 5, pink or white; stamens 5; ovary chamber 1, placentas basal, style 1, stigmas 3. Fruit: valves 3, margins inrolling, forcibly expelling seeds. Seed: 3–6, generally black, generally appendaged.Key to Claytonia
27 species: Central America, North America, eastern Asia, Siberia. (John Clayton, colonial American botanist, 1694–1773) [Miller & Chambers 2006 Syst Bot Monogr 78:1–236]
Unabridged references: [Miller 2003 FNANM 4:465–474; Miller & Chambers 1993 Novon 3:268–273; Miller & Chambers 2006 Systematics of Claytonia Syst Bot Monogr 78:1–236]
Annual. Stem: 1–40 cm, spreading to erect. Leaf: basal 1–25 cm, blade < 4 cm, < 3 × longer than wide, elliptic to reniform, tip rounded to acute, petiole linear; cauline fused into < 10 cm diam, round, ± obtuse-angled, or ± square disk (or free on 1 side). Inflorescence: stalked or not, open or dense, 1-bracted at base; flowers 5–40. Flower: sepals 1.5–5 mm; petals 2–6 mm, white or ± pink. Fruit: 1.5–4 mm. Seed: 1.2–2.7 mm, ovate to round, shiny, smooth. Highly variable; subspecies difficult because of environmental modification of character states, genetic mixing among polyploids, and geographic overlap of distinct, self-pollinated forms.

Leaf: basal elliptic to deltate, tip obtuse to acute (mucronate); cauline generally round or ± obtuse-angled.
2n=24,36,48,60. Vernally moist, often shady or disturbed sites; < 1000 m. California Floristic Province; to British Columbia, Montana, Utah, central Arizona. Polyploids from hybrids with Claytonia perfoliata subsp. mexicana, Claytonia parviflora, Claytonia rubra. Jan–May [Online Interchange]
