The material collected shows considerable variations as to shape and size of the 

 leaflets, pubescence of the plants, floweriness, etc. The shape of the leaflets varies from 

 nearly ovate to very oblong, about 6 times as long as broad. The subulate, mucronulate 

 stipules are partly entire, jjartly serrulate at the margin. The raceme rather flowery, ge- 

 nerally containing 8—14 flowers. Length of the fully developed flowers 10—12 nnn. Of 

 very common occurrence on the Abakan Steppe and on the islets in the lower part of 

 the river, in open, sunny places, on stony declivities, in dry, sandy and stony grass- 

 field, etc., where I have collected it with young flowers and flower-buds in the first 

 half of June. It is also scattered on the road between Karatus and Kushaliar, at Ust Sisti- 

 kem, and on the steppes al^out the Ulu-kem. 



Distribution: Europe, except the extreme north, the Caucasus, Siberia, northwards 

 to about 60" north lat., and eastwards to Trans Baikal, Mongolia, northern Cliina, 

 south-western Asia to Afghanistan and Turkestan, the East Indies.
