This pretty, little Gentiana is scattered on the islets in the rivers Yenisei and Aba-

 bear fully opened flowers, specimens collected in the second half of the same month are 

 nearly past flowering, most of them with ripe, partly emptied capsules already.

In the territorj' explored this species is of about the same distribution as the preced- 

 ing one, together with 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 northwards 

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

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