| Description: |
Coarse tufted perennial grass with a strong root-system and unbranched culms, up to 2 m tall, 2–5 mm in diameter at the base (sometimes less), erect, unbranched; basal leaf sheaths chartaceous, glabrous, slightly compressed to strongly keeled, persistent; leaf laminas up to 50 cm × 3–10 mm, flat (folded on drying), smooth and glabrous on the surfaces and margins, tapering to a flexuous filiform apex. Inflorescence an open panicle of pyramidal shape, 20–45 cm long; inflorescence branches not whorled, spreading horizontally at anthesis, the longest 5–10 cm long, scaberulous, eglandular, subsecund, the spikelets densely (sometimes rather loosely) arranged along their whole length, sometimes on short secondary branchlets. Spikelets very small, (1.4)1.7–2(2.3) mm long, grey to purple; inferior glume 1/5–1/3 the length of the spikelet, broadly oblong, hyaline, nerveless, glabrous, obtuse to truncate at the apex, sometimes irregularly toothed or erose; superior glume 1/3–1/2(3/5) the length of the spikelet, broadly oblong to broadly ovate or even oblate, hyaline, 1-nerved, scaberulous on the nerve, broadly obtuse to truncate at the apex, often apiculate, sometimes ± 3-lobed, irregularly toothed or erose; lemma as long as the spikelet, ovate-elliptic, acute at the apex; anthers 3, 0.6–1.1 mm long. Grain 0.8–1 mm long, obovate, conspicuously truncate, laterally compressed and oblong in section. |
