This one is comparatively low, with ascending stems, and the whole plant is rather 

 densely puberulcnl. The leaves are frequently 4- to 6-divided, and the leaflets, the shape of 

 which is ovate-lanceolate, twice to four times as long as broad, to 20 mm. long, and 6—7 

 mm. broad, opposite or alternate, a character varying even in the very same plant. The 

 leaflets are generally entire, more rarely 2-cleft at the summit, both of which shapes may 

 sometimes be met with in the very same individual. Some specimens approaching /. gla 

 brata, have the upper sides of the leaves completely glabrous, the veins beneath, and also 

 the petioles and stems only sparingly pubescent. The floweriness is very varying, and 

 the colour of the leaves changes between a deep green, with lighter under sides, and 

 nearly bluish green.

This variety, which is distinguished by being densely tomentose-canescent and by 

 having leaves with rather numerous, small, broader, approximate pinnae and compa- 

 ratively small flowers, I have found on dry declivities on the steppes between Minusinsk 

 and Ust Abakansk. Flowering at the beginning of June. 



Distribution: Eastern, central, and southern Russia, westwards to Roumania, Asia, 

 except the extreme south.

Common on the Abakan Steppe, on sunny, rocky slopes, in diy meadows, and the 

 like, where the species begins flowering in the second half of June. In the Urjankai 

 country I have found the species on the steppes about the Ulu-kem, from Bjelosarsk 

 westwards towards Cha-kul, where the specimens were past flowering at the end of 

 August.

Scattered on the steppes about the river Abakan, in dry grass-field, on dry rocks, 

 and, as it seemed, sometimes in somewhat saliferous soil, for instance near Ust 

 Kamuishto. In flower in the middle of June. 



Distribution: In Europe in the western Alps, Lapland, Spitzbergen, northern Russia, 

 temperate parts of Asia, in Siberia northwards to 66° north lat.. North America?
