In the territory ex])lored this species is of al)out the same distiibution as the preced- 

 ing one, together \\\[h which it also sometimes occurs: it seemed, for the rest, to prefer 

 somewhat drier localities. To judge from the material collected, it is somewhat rarer, and 

 its flowering season also seemed to begin a little later than in the preceding species. On 

 islets in the Yenisei, near Ust Abakansk. 



Distribution; Russian Turkestan, southern Siberia, in the Yenisei valley nortliwards 

 to about 59° north lat., and eastwards to the Amoor Province, Manchooria, Mongolia, 

 western Tibet, northern India, Corea, China, Japan.
