Pretty common on islets in the river Abakan, and in moist places on the Amyl, near 

 Kushabar. In the month of June, I have only collected young, flowerless plants. In the 

 Urjankai country I have collected the species at Ust Sisti-kem and at Ust Tara-kem, near 

 the river. 



Specimens from the different localities vary rather much in stature, in hairiness, 

 ramification, shape of the leaves, length of the petioles, etc.
