Subalpine and alpine meadows, alpine tundra, usually above 2000 m.
A variable complex of regional populations characterized by long anthers, usually much longer than the filaments, usually interrupted or distinctly lobate inflorescence, and large capsule segments and seeds. Local populations often are relatively distinctive, deviating from the average values in a number of quantitative characters. However, numerous substantial overlaps of the quantitative character ranges do not allow recognition of the local types at a rank higher than variety. A unique feature is the multiple, fixed occurrence of 2n=16=8AL+8BL in the Caucasus.
