This species seemed — at 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 the Yenisei valley northwards to about 70° 20' north lat. (the occurrence 

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

subspec. distentum nov. subspec. 



Ab forma typica differl pedunculis omnino glabris, minquam retroisus hispidiilis, 

 ad 12 mm. longis, capillaribus, plus minus reciirvatis, vulgo unifloris. Corolla 3- vel 

 interdum i- partita, laciniis ovalis. Fructibus levibus, globosis, distantibus, nunquam 

 connatis. Caules tenui, altius sulcaii, angulaii. Folia glabra. 



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
