This species is very common on dry steppes, and in dry, sandy situations in open 

 pine-wood about Minusinsk. On the Abakan Steppe almost exclusively covering 

 the ground over large tracts of land. It appears from the rather rich material brought 

 home by me from the Minusinsk district that it occurs in those regions in a multitude of 

 varieties. From the diagnosis only of the numerous subspecies, varieties and forms 

 belonging to this species, given by Domin, 1. c, I dare not classify my material defini- 

 tely. Some seemed to be intermediate forms, passing into the following species, and may 

 possibly have to be regarded as hybrids between them. I have also observed this species 

 in many places on the steppes on the river Ulu-kem. 



Distribution: Over the greater part of Europe, except the northern and southern 

 parts, temperate portions of Asia, Africa, North America.

Seemed to be of rare occurrence in the territory explored. A few specimens gathered, 

 by me in dry, sandy places on the Abakan Steppe, near Ust Kamuishto. With young 

 flowers at the end of June.
