This is a plant of veiy common occurrence in the territoi-j' traversed, where 

 especially to be met with on shallow sands on the banks of rivers, among loose stones and 

 gravel in the river-bed, where it sometimes grows rather far out in the streams, even 

 where they arc rather rapid. In such habitats it is a very characteristic plant. I have also 

 collected it in more muddy soil, in stagnant water on islets in the rivers Yenisei and Aba- 

 kan, and in streams between Minusinsk and Kushabar; very common in the Amyl valley, 

 on the rivers Sisti-kem and Kamsara, and in several places on the Bei-kem. The species 

 flowers at the beginning of June. 



Distribution: Bohemia (an escape from cultivation?), north-eastem Russia and Sibe- 

 ria, northwards to about 66K'° north lal., eastwards roughly to the Yenisei, northern 

 Mongolia.
