On dry, sandy hills in open pine-wood, near the salt lake Tagarski osero at Minu- 

 sinsk, where of rather common occurrence, and also on the Abakan Steppe, near Ust 

 Abakansk. 



In my material from those regions there occur specimens with one solitary, high, 

 erect stem, « slricla Leder. 1. c, and specimens with several shorter, decumbent and 

 ascending stems, ^ adscendens Ledeb. 1. c. In full flower in the first half of July. In the 

 Urjankai country I have found the species scattered on dry steppes on the river Bei-kem 

 at Ust Kamsara, Ust Tara-kem and on the Ulu-kem, between Ust Tapsa and Cha-kul, 

 where it was past flowering, bearing fruits at the end of August and the beginning of Sep- 

 tember.
