Pretty common in slow streams and still creeks of the rivers Abakan and Ka-

 near the Dora Steppe. Specimens collected about the middle of June bearing already 

 ripe fruits of a black colour. 



Besides the typical species, with leaves about 1 mm. broad, I have collected, in the 

 river Kamuishto, near its mouth, specimens of /. rhaetica Zschokke, distinguished by 

 filiform and comparatively short leaves, hardly 0,5 mm. broad.
