This characteristic species is pretty common in the Altaian, on mountain-sides, at 

 an altitude of about 1900—2000 m. above sea-level, in places covered with stony debris, 

 among shrubs, etc. It seemed to prefer here the south sides of the mountains, and is one 

 of the prettiest and most conspicuous alpine plants in these regions. Collected in full 

 flower at the end of July. 



Distribution: Turkestan, the Thian-Shan, southern Siberia, eastwards roughly to 

 Trans Baikal, northern Mongolia, northern China.

Scattered on the steppes about the river Abakan, especially on rocks, among stones 

 and gravel along dried up brooks' courses, etc. In full flower in the middle of June. In 

 the Urjankai country the species is characteristic of dry, open declivities and rocky 

 slopes in the genuine wooded steppe region, where I have met with it at Ust Kamsara and 

 at Ust Tara-kem. 



Distribution: Russian Turkestan, Cashmere, southern Siberia, in the Yenisei valley 

 northwards to about 66° north lat., and eastwards roughly to the Lena, northern Mon- 

 golia.
