Common Name: PUSSYPAWS
Habit: Annual, perennial herb, +- fleshy, from taproot or fibrous roots, glabrous. Stem: 1--several, generally spreading to ascending. Leaf: basal or basal and cauline, simple, oblanceolate to spoon-shaped; basal rosetted. Inflorescence: raceme, panicle, or umbel, scapose, bracts generally < sepals, leaf-like or not; flowers generally on 1 side of axis, persistent in fruit or not; pedicels appearing jointed at base with a transverse groove or constriction or not. Flower: sepals 2, ovate to reniform, generally scarious or scarious-margined, persistent in fruit; petals 2--4, < sepals, tips adherent, forming cap in fruit (fruit cap), falling as 1 unit; stamens 1--3, anthers pink, rose, or yellow; style included to exserted, stigmas 2.
