Perennial, slender, up to 32 cm tall, with a swollen culm base covered by 1–2 cm long, thick, reddish brown old basal leaf sheaths looking like scales, with prominent pale veins or fibres, the whole forming a bulb-like structure; each bulb producing one fertile culm and later in the season one to several leafy shoots.
Morphology Culms
Culms 15–30 cm long, 0.6–1.2 mm wide, trigonous, almost glabrous
Morphology Leaves
Leaves with reddish brown sheath 1–2 cm long; blade linear, on fertile culm 2–4 cm long, ± 2 mm wide, on leafy shoots up to 5 cm long, ± 2 mm wide, probably longer later in season
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts 3. Leaf-like, reflexed, lowermost 1–3 cm long, 2 mm wide
Morphology Reproductive morphology Inflorescences
Inflorescence capitate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets in a solitary globose to hemispherical head 9–10 mm in diameter, individual spikelets linear-lanceolate, 4–4.5 mm long, 0.8–1 mm wide, one-flowered.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes yellowish-white, lower glume ovate, 2.5–3 mm long, many-veined, apex concave, upper glume ovate-lanceolate, convolute, 4–4.5 mm long, entirely covering the nutlet
