Leaves: basal leaves 15–45 × 0.5–2.1 cm proximally, shorter distally; cauline leaves shorter than basal, decreasing in size distally, becoming bracts in inflorescence. Inflorescences initially rounded, becoming open and corymbose after anthesis, each branch resembling a helicoid-cyme. Flowers: tepals erect-spreading at anthesis, pale-yellow, 7–9 × 1–1.5 mm, densely pubescent abaxially, persisting and incurving to form beak around fruit; stamens spreading at anthesis; filaments 8–10 mm; anthers yellow; style persistent, slightly exceeding anthers, 10–13 mm. Capsules globose or oblate, 3–5 mm diam. Seeds reddish-brown, 2.5–3 mm diam., faintly wrinkled. 2n = 48.
