Poaceae

E. repens(L.) Gould in Madrono 9:127(1947).
Perennial with long-creeping rhizomes. Stems 30-80 cm, glabrous. Leaves 3-10 mm broad, usually flat, scabrid or sparsely pilose. Spike usually 5-15 cm,dense or lax; rachis spinulose-ciliate on main angles. Spikelets ± compressed . laterally. Glumes 5-10 mm, lanceolàte, 3-7-veined, slightly scabrid on midvein towards apex, acute or acuminate, usually mucronate. Lemma glabrous.
1. Glumes usually acuminate or with short awn to 3 mm; lemma 8-11 mm, acute, mucronate to shortly awned; palea ciliate throughout most of length of keels subsp. repens
1. Glumes acute or with short, obtuse mucro to 0.2 mm; lemma 6-10 mm, unawned, often emarginate at apex, with short thick point, not projecting beyond apex;palea minutely ciliate on keels in upper part subsp. elongatiformis

Distribution of species: as subsp. repens. Very polymorphic; numerous variants have been described but they show considerable overlap in characters. Although subsp. elongatiformis usually has glabrous leaves, the upper surface is occasionally pilose (e.g. B9 Bitlis: Tatvan, 2010-2135 m, Tong 103!). This character cannot, therefore, be used to separate subsp. elongatiformis from subsp. repens.
