Hainardia cylindrica (Willd.) Greuter

Small annual tufts 10–30–(45) cm, often growing closely together to form large patches, plants usually rigidly erect but sometimes with shoots appressed to ground. Leaf-sheath submembranous, glabrous, straw-coloured, striate. Ligule 0.2–0.7 mm, membranous, glabrous, truncate, erose, projecting slightly upwards on either edge. Leaf-blade 2.5–9–(11.5) cm × 1.2–1.7 mm, flat, or inrolled and c. 0.5 mm diam., abaxially glabrous, adaxially ribbed, ribs minutely scabrid. Culm 5–30 cm, sometimes purplish, usually branched near base, internodes glabrous. Inflorescence a single simple spike, breaking up at maturity by disarticulation of rachis below each spikelet. Spikes 6.5–15 cm, cylindric, rather thick, straight or slightly curved, light green; rachis internodes ≤ spikelets, hollowed on one side. Spikelets 5–7.5 cm, 1-flowered, sessile, solitary, edgewise to rachis, alternating on opposite sides of rachis, ± sunk in cavities within it; each floret ± concealed by one glume, uppermost floret with 2 glumes. Glumes 9-nerved, very hard, thick and rigid, oblong-subulate, acute, outer nerves slightly scabrid near apex; glume concealing floret at first, but later sometimes recurved and projecting stiffly at 45 from the rachis. Lemma 4.5–6.2 mm, with back appressed to rachis, membranous, finely 3-nerved with lateral nerves indistinct, lanceolate, acute, glabrous. Palea ≈ lemma, 4–5.5 mm, hyaline, glabrous, keels 2, indistinct. Lodicules 2, glabrous, 1–1.5 mm. Stamens 3; anthers 1.5–2.5 mm. Caryopsis c. 3–3.5 × 0.8–1.1 mm, longitudinally grooved; embryo small; hilum short, linear to oblong.
