Saxifraga sibirica var. eusibirica Engl. & Irm.
Herb, 7-30 cm tall, pubescent. Basal leaves 5-35 mm broad, reniform, with 5-7 lobes; upper most cauline leaves subsessile, trilobed to ovate; sparsely pubescent to glabrous; basal leaf petiole, 2.5-4 cm long, glandular; bulbils in basal leaf axils. Flowers white, 1-6, pedicels densely villous. Bracts ovate, 3 mm long. Sepals 3-4 mm long, oblong, acute, glandular-pubescent. Petals 1-1.3 cm, obovate, cuneate at the base, 3-7-nerved. Ovary superior. Seeds oblong; testa minutely reticulate.
Fl.Per.: Late June-August.
Type: Described from Siberia, Hb.Linn.575/49. (LINN).
Distribution: Siberia, Europe, N. & C. Asia, W. Himalayas.
Common on moist rocky slopes in shady areas or on rocks in stream beds, in upper Swat, Kaghan, Gilgit, Baltistan and Kashmir areas from 3500-5500 m. Resembles the previous species but generally smaller in stature and leaf size and with fewer leaf lobes.
Lozinskaya in (Kom.,Fl.URSS.9:172.1939) describes as Saxifraga mollis Sm. plants similar to Saxifraga sibirica but with narrower and longer 3-nerved petals. R.R. Stewart 19959, 7263½, Koelz 1266, M. Nath 1538 have 3-5-nerved petals and the shape of the petals is not always constant. Therefore I have treated Saxifraga mollis Sm. conspecific with Saxifraga sibirica and not as an independant species.
