Poaceae

E. hispidus (Opiz) Melderis in Bot. J. Linn. Soc. 76:380(1978).
Perennial with often long-creeping rhizomes. Stems 40-80 cm, usually glabrous, sometimes densely and minutely pubescent on nodes. Leaves 2-6 mm broad, usually flat, glaucous-green, closely and rather prominently veined, with conspicuous marginal veins, scabrid, often also sparsely long-pilose on upper surface, usually glabrous beneath; sheaths usually long-ciliate. Spike 10-20 cm, erect, rather dense to lax; rachis spinulose-ciliate on main angles. Spikelets with 4-6 florets, compressed laterally. Glumes 5-8.5 mm, subequal, oblong or lanceolate-oblong, usually 5-veined, scabrid on keel towards apex, usually obtuse or obliquely truncate to truncate, with small triangular point or mucro at apex, sometimes subacute. Lemma 8-11 mm, keeled at apex, usually obtuse or mucronate. Palea ciliate on keels.

Exped. 1970:7-8-2-A! have very hairy spikelets, leaves and sheaths and closely match the type of Agropyron aucheri Boiss., described from Iran (Pere Zend, Aucher 5424, G!), but within the area there also occur less hairy plants which approach European populations of subsp. barbulatus. A comparison of the holotype of A. aucheri, and syntypes from Turkey, with authentic material of A. barbulatum (W!) shows that they differ only in the degree of hairiness, which cannot be considered an essential diagnostic character.
