Description
Densely tufted; tufts very small, bright green or yellow-green. Culms 2–7 cm. long, enclosed by light to dark brown lf-sheaths almost to the top. Lvs much > culms, 3–9 cm. × 0.5–1 mm., concavo-convex, almost flat, bright green or yellow-green, rigid, coriac., linear, gradually tapering above, margins scabrid, tips subacute, incurved when dry; sheaths twice as broad as lamina, pale brown with membr. edges. Infl. a close-packed head of 3–5 spikes; terminal spike male; lower spikes female, 4–8 mm. long, ovoid or oblong-ovoid, greenish-brown, sessile or the lowest very shortly pedunculate; spikes subtended by lf-like bracts > infl. Glumes < or ± = utricles, ovate or almost orbicular, acute or with a longer scabrid awn, nerved, membr., red-brown with a pale centre and margin, or almost entirely pale straw-coloured.
