Only some specimens of this one found by me on the sandy banks of the river 

 Abakan, near Ust Kamuishto. With ripe fruits at the end of June. The segments of 

 the leaves are linear, from 1—2 mm. broad, acute at the summit. The outline of the 

 leaves triangular to ovate. 



Distribution: Europe, except middle and eastern Russia, Siberia, Mongolia, north-

The rather numerous specimens collected by me, have always unbranched, one- 

 flowered stems, from 12 to 20 cm. high. The pinnae of the leaves are always markedly 

 petioled, the length of the petioles in the lower pinnae generally 5 mm., in the upper 

 ones generally somewhat shorter. The outline of the pinnae is roundly ovate, and rather 

 deeply incised into nearly linear lobes, from 1 to 2 mm. broad, subobtuse or slightly 

 subacute at the top. The lower pinnae generally tripartite. The stem bears a sessile, 

 triparted leaf above the middle, more rarely 2-leaved, of which the lower leaf is always 

 petioled. The sepals are nearly ovate, 7 to 8 mm. long, the petals narrowly obovate, 12 

 to 14 mm. long, broadly rounded at the top, tapering towards the base, where furnished 

 with an orange-coloured spot. The whole plant is of a dull, yellowish colour. 



Rather common in the Altaian, in moist, gravelly places, at altitudes of about 2100 

 m. above sea-level, in full flower at the end of July. 



Distribution: Southern and middle Europe (the Alps), Russian Turkestan, the 

 Thian-Shan, the Altai, the Sayansk district, the Yablonoi.
