Annuals, (5–) 14–20 (–30) cm tall, dark green, usually caespitose, ±robust, seldom one-stemmed. Basal leaves usually 2–8 cm long, c. 0.6–1.1 mm wide, flat to canaliculate. Cauline leaves usually 1–3, often equalling to exceeding inflorescence; auricles absent in leaves, some-times developed in lower bracts. Lower bracts leaf-like, long. Inflorescence usually constitutes only 1/3–2/5 of plant height, usually many–50-flowered, of several sickle-shaped cymes, in 2–6-flowered fan-shaped clusters. Bracteoles ovate, 1.5–2.5 mm long, scarious. Tepals broadly lanceolate, unequal. Outer tepals acute to acuminate, 4.9–7.5 mm long; central band pale green to stramineous; margins broad, membranous. Inner tepals c. 4.0–6.0 mm long, subobtuse to ±acute. Stamens 6, less than 1/2 as long as tepals; anthers 0.4–0.8 (–1.0) mm long; filaments c. 0.7–2.0 mm long; style 0.2–0.5 mm long; stigmas 0.5–1.0 mm long. Capsule oblong(–ovoid) to ±ellipsoid, subtrigonous, c. 3.5–4.5 mm long, slightly shorter than inner tepals, usually subacute, less often ±acute to obtuse. Seeds ±ovoid, 0.3–0.4 × 0.2–0.3 mm, almost smooth, very faintly reticulate; appendages absent. 2n = 34, fide S.Snogerup, in K.H.Rechinger, Fl.
