( C. beeringianum sensu Schischkin , non Cham. & Schlecht.).

Perennial 10-30 cm; flowering stems slender, with long internodes, sparsely hairy with short patent hairs or subglabrous; basal branches stolon-like, leafy, axillary bulbils usually present. Leaves 1 0x4 mm, elliptical, acute, pubescent, at least marginally and along the veins. Flowers 3-7, in lax cymes; pedicels glandular-pubescent; upper bracts small, acute, with narrow scarious margins. Sepals 3-5 mm, acute, with scarious margins; petals about twice as long as sepals. Capsule 8-12 mm, curved; teeth erect or somewhat patent, with revolute margins. Seeds c. 1 mm, strongly tuberculate. Subarctic Russia and N. Ural. Rs (N).

C. beeringianum Cham. & Schlecht. , Linnaea 1: 62 (1826) (C. bialynickii Tolm.) is like 24 but more compact and lowgrowing, with rigid erect flowering stems, lacking long runners and axillary bulbils, and having petals only slightly longer than the obtuse sepals. It has been recorded from Poluostrov Kanin but the identity of specimens available is not quite clear.

C. gorodkovianum Schischkin in Komarov, Fl. URSS 6: 883 (1936) from N. Ural seems also to be close to 24 but has petiolate lower cauline leaves, somewha 1larger sepals, and petals not very much longer than sepals.
