27. C. arcticum Lange View in CoL , FZ. Dan . 50: 7 (1880).

Perennial 2-15 cm, with subterranean runners. Leaves usually 1 0-1 5x4- 5 mm, mostly narrower than in 26(c). Flowers 1-3; bracts herbaceous. Sepals 6-9 mm, ovate to ovate-lanceolate with wide scarious margins; petals 2 or more times as long as sepals, shallowly bifid. Capsule broadly cylindrical, with wide mouth, almost straight, up to twice as long as sepals. Seeds 1-1-5 mm, rugose; testa close. N.W. Europe extending to Svalbard and N. W. Finland. Br Fa Fe Is No Sb Su.

Very variable in leaf-shape, hairiness, etc., especially in the Arctic. To some extent this variation may be due to hybridization with 25 and 26. At present it seems best to distinguish only the following two subspecies.
