The specimens collected are distinguished by their very long and narrow leaves, 

 the lower ones linear, from 1 to 1.3 mm. broad, and from 4 to 7 cm. long, the upper 

 ones linear-filiform, 0,3 mm. broad, and from 3 to 4 cm. long, more or lesse acuminate at 

 the summit. The leaves are entire; only some of the lower ones having one or a few 

 awl-shaped teeth about the middle of the leaf. The plant is glabrous all over, the sepals 

 included. In point of their narrow leaves these specimens recall in a high degree var. 

 soongoricum Regel-Herder in Bull. Soc. Imp. Nat. Moscou (1864) p. 141. no. 98 b, and in 

 point of their completely glabrous sepals var. laii folium Korsh. in Fragm. Fl. Turk. I 

 (1898) p. 412, no. 24. The stems are solitary, unbranched in the lower part, and in the 

 upper part with one or a few short branches, only 1 to a few cm. long. The petals are 

 small, from 5 to 6 mm. long. Taken ou the Abakan Steppe, near Ust Kamuishto. In 

 full bloom in Ihe second half of June. 



Distribution: In middle Europe from Hungary to the west, through southern and 

 middle Russia and adjoining portions of Asia to Turkestan, Siberia, and Trans Baikal, 

 northwards and eastwards right up to the Upper Lena and the Upper Kolyma.

In the territory explored, the species varies veiy considerably in hairiness, rami- 

 fication, height, and above all, in the size of the leaves, and the breadth of tlie segments. 

 In dry places, for instance in the steppe regions about the river Abakan, the segments 

 are generally very fine, almost filiform, and like the plant in general, rather densely 

 hair)^ whereas, in humid habitats, besides being more vigorous in growth, having con- 

 siderably broader segments as well; breadth of the lobes to 2 mm. in Uie specimens 

 gathered, and the whole plant glabrous, and of a fresher green. The species is rather
