( K. alpigena Domin , K. cristata (L.) Pers , pro parte, K. gracilis Pers. , K. sclerophylla P. Smirnov ).

Laxly caespitose, sometimes with creeping rhizomes. Stems 10-40 cm, usually glabrous or puberulent. Leaves of non-flowering shoots up to 15 cm X 1-2 mm, usually flat or plicate, green or sometimes glaucous; sheaths persistent, glabrous or hairy, with parallel veins. Panicle 20-80(-100) x c. 10 mm, narrowly oblong, more or less lobed especially below. Spikelets 2—5(—6) mm. Glumes unequal, acuminate, mucronate or shortly aristate, green, brown or purplish, with silvery hyaline margin. Lemma acuminate, glabrous. 2« =14, 28 + 0-6B, 42, 70. Europe northwards to N. Scotland and Lithuania; casual in Fennoscandia. Al Au Be BI Br Bu Cz Ga Ge Gr Hb He Ho Hs Hu It Ju Po Rm Rs (B, C, W, K, E) Tu.

Very variable in habit, leaf-size and indumentum. Populations with apparently distinctive combinations of these characters have been described as separate taxa, but it is generally not possible to distinguish them from the remainder by any single character. Laxly caespitose rhizomatous plants with slender somewhat glaucous leaves, from C. Russia and N. Ukraine, separated as K. delavignei Czern. ex Domin , Biblioth. Bot. (Stuttgart) 65: 247 (1907) (inch K. incerta Domin ), are perhaps worth specific status.
