Annuals, 8–14 (–20) cm tall, usually caespitose. Leaves basal and sub-basal, usually to 8 cm long, 0.5–0.8 mm wide, slightly canaliculate; sheaths abruptly dilated in broad membranous margins; free auricles absent; apex acute-acuminate. Lower bracts usually filiform, c. 2.0–6.5 cm long, exceeding inflorescence. Inflorescence of 1–5 dense congested to subcongested fan-shaped heads, each composed of 4–6 abbreviated 3–6-flowered branches. Bracteoles membranous-scarious, c. 2.0–2.5 mm long. Tepals conspicuously unequal. Outer tepals longer acuminate-aristate, c. 5.5–8.2 (–8.5) mm long; central band yellowish green to stramineous, densely veined; margins scarious, c. 0.3–0.4 mm wide. Inner tepals c. 4.5–5.5 (–6.5) mm long, acute or subacute, with a broad membranous margin. Stamens 6; anthers c. 0.7–1.2 mm long, usually slightly shorter, rarely longer than c. 0.8–1.1 mm filaments; style c. 0.2–0.4 mm long; stigmas c. 0.5–0.7 mm long. Capsule oblong-ovoid to oblong-subtrigonous, 3.0–4.5 mm long, substantially (2/3–4/5) shorter than inner tepals, subabruptly contracted in a conical apex. Seeds ±broadly ovoid, 0.35–0.45 × c. 0.3–0.4 mm, very finely and minutely reticulate; appendages absent. 2n = 28, fide T.A.Cope & C.A.Stace, Watsonia 12: 127 (1978); T.A.Cope & C.A.Stace, Watsonia 15: 311 (1985).
