Dieter H. Wilken and Walter A. Kelley

Annual, perennial herb, ± fleshy, from taproot or fibrous roots, generally glabrous
Stems generally several, generally spreading to ascending
Leaves in basal rosette or basal and cauline, simple, oblanceolate to spoon-shaped
Inflorescence: raceme, panicle, or umbel, scapose, leafy, or bracted; flowers generally on 1 side of axis, deciduous or persistent in fruit; bracts generally < sepals, scarious
Flower: sepals 2, ovate to reniform, generally scarious or scarious-margined, persistent in fruit; petals 2–4, minute, < sepals, tips adherent and cap-like in fruit, falling as 1 unit; stamens 1–3; style 0 or 1, thread-like, stigmas generally 2
Fruit: capsule, generally translucent, 2-valved, generally compressed, oblong to ± round
Seeds 1–many, black, generally shiny
Species in genus: 8 species: w Am
Etymology: (Greek: cap, from petals in fruit)
