Perennials; long-lived; sexual; caudex woody (with persistent, peg-like leaf bases). Stems usually 1 per caudex branch, arising from center of rosette, elevated above ground surface on woody base, 0.8–4.5 dm, pubescent proximally, trichomes stalked, 2–4-rayed, to 0.5 mm, mixed with simple ones, to 1 mm, glabrous distally. Basal leaves: blade narrowly oblanceolate, 1–3 mm wide, margins entire, ciliate proximally, trichomes (simple), to 1 mm, surfaces moderately to sparsely pubescent, trichomes stalked, 2–4-rayed, 0.1–0.3(–0.5) mm. Cauline leaves: 3–17(–30), rarely concealing stem; blade auricles 0.5–2.5 mm, surfaces of distalmost leaves glabrous. Racemes 6–20(–35)-flowered, usually unbranched. Fruiting pedicels divaricate-ascending to horizontal, straight, 10–18 mm, glabrous or sparsely pubescent, trichomes spreading, simple and 2-rayed. Flowers ascending at anthesis; sepals pubescent; petals deep purple to magenta, 8–12 × 2.5–4 mm, glabrous; pollen ellipsoid. Fruits divaricate-ascending to widely pendent, not appressed to rachis, not secund, usually curved, rarely straight, edges parallel, 5–7.5 cm × 1.8–2.5 mm; valves glabrous; ovules 58–94 per ovary; style 0.05–0.2 mm.
