On the islets in the rivers Yenisei and Abakan this species is very common, and 

 occurs in different forms. Forms are to be found here recaUing much f. Friesii Gn. et 

 Good., f. velutinus Lindbl., f. califotniciis Benth., and intermediates between these. 

 Whether the specimens be quite identical with the said forms, I dare not assert with 

 absolute certainty, my material being too scarce. The species is also very common in 

 the Urjankai country. On the banks of the Bei-kem, near Utinski porog, in grassy 

 places, near the river, I have collected a very low form, with stems, only 5—10 cm. 

 high, with 1 or 2 flowers, and which seemed to be identical with f. pumilus Wahlenb.

This one constitutes, in many respects, an intermediate between the typical R. 

 auricomus and R. cassubicus, and is, in preference, distributed in the eastern geogra- 

 phical area of the species. 



In humid, grass-grown places, in thickets on the road between Minusinsk and 

 Kushabar, and on the river Amyl. In flower in the middle of Jiily. 



Distribution: The species is distributed over Europe, Caucasia, Siberia, Manchoo-
