Leaf blades erect, glabrous, or scabrid near tip (irregularly curled and scabrid all over in subsp. caucasica), acute, sometimes pungent, lowest 1/3-1/5 x uppermost, (0.4-)0.5-l(-l.l) mm broad; veins 7-11, ribs 5-9, prominent for 1/2 their length or more, usually broadly rounded, lateral ones (in cross section) resembling an anvil, with or without a short row of sclerenchyma cells above, glabrous or hairy above; sclerenchyma ring of 1-2 (rarely 2-4) rows of cells, cells (l/8-)l/6-2/3(-l) x epidermis cell. Panicle 4-10 cm, erect, oblong; branches slender, subflexuous, bearing few to many short or ± long hairs. Spikelets variegated light green and violet (glaucous and pale violet in subsp. caucasica), 8-12 mm, with (3-)4-6 florets.
