Descriptions
Small loosely hummock-forming low grass with short glaucous falcate or sinuous leaf-blades, and prostrate to ascending culms; branching intra- and extravaginal sometimes forming short stolons. Leafsheath 2–5 cm, striate, retrorsely pubescent or glabrous, sometimes with a few long hairs; becoming a short lobe at apex. Ligule 0.3–0.5 mm, erose or finely toothed. Collar thickened, curved, glabrous or short hairy, margins with hairs 1.5 mm long. Auricles absent or minute, with 1–2 long hairs. Leafblades 5–15 cm × 0.5–0.7 mm diam., ± terete, involute, keeled but only faintly ridged, falcate, sinuous or irregularly curled or ± straight, abaxially glaucous with scattered to abundant stiff erect or somewhat retrorse hairs 0.5–1 mm long, becoming glabrous, or pubescent below becoming glabrous, or glabrous throughout; adaxially with abundant 0.3 mm hairs or shorter hairs and/or prickle teeth; margin prickle-toothed or with hairs 0.5 mm long. Culms 10–35 cm, prostrate to ascending; internodes smooth, glaucous. Inflorescence 2–10 cm, of 1–4 spikelets; rachis margin often glabrous. Spikelets 40–50 mm, of 4–6 shining florets. Glumes ± equal, 4–9 mm, keeled, 3-nerved, sometimes becoming awned, glabrous, margin chartaceous. Lemma glabrous except for prickle teeth on keel above and on margins below extending into reflexed awn 30 – 50 mm; pruinose. Palea 7–10 mm, apex pointed, bifid. Rachilla 1.5–2 mm, short stiff hairy. Callus 0.75 mm, very shortly bearded, hairs ≤ callus. Lodicules 1.2–1.4 mm. Anthers 2.4–2.5 mm, yellow. Gynoecium: ovary 1.5 mm; stigma-styles 2.5 mm. Caryopsis 6–6.5 mm; embryo 1 mm.
E. sacandro similis sed statura multo breviore, caespites prostratos faciens in mediterreis regionibus . Laminae saepe falcatae vel sinuosae, abaxialiter pilis sparsis, longis (c . 1 mm), erectis praeditae; adaxialiter pili longi adsunt tamen nullo modo congregatim in flocco denso ut in E . sacandro . Inflorescentia saepe plane brevis cum E. sacandro/E. solandri congruens.
