This species seemed — al any rate to judge from my observations — to be rather rare 

 in the territory traversed, where I have met with it only in a single locality, viz. near Ust 

 Algiac, in damp and shady places, associated with the preceding one. 



Distribution: Europe, except the most southern parts, Caucasia and south-western 

 Asia, Siberia, in tiie Yenisei valley northwards to about 70° 20' north hit. (the occurrence 

 reported in eastern Siberia is dubious). North Africa, North America, Greenland.

Specimens of this one somewhat resemble Galium palustre L. as to stature: in their 

 comparatively coarse, erect stems, attaining a length of 25—30 cm., with rather long
