Pretty common in brush-wood and in slightly moist, grass-grown places on islets in 

 the river Abakan, near Kushabar, in the Amyl taiga, and, moreover, rather frequent in 

 the Urjankai country, about Ust Algiac, and on the Kamsara. The species begins flower- 

 ing about the middle of July. In the taiga territory this species is frequently to be found 

 associated with Delphinium datum, and sometimes Veratrum album, forming in places 

 a dense, nearly impenetrable growth, 2 — 3 m. tall.

 wards roughly to the governments of Yakutsk and Irkutsk, Turkestan, northern Mongolia.
