Pretty common in grass-grown places on islets in the Yenisei and the Lower Aba- 

 kan. With flowers and fruits in June. In both localities the specimens collected are 

 not quite typical, but somewhat recall Taraxacum gotlandicum Dahlst. in Bot Not. 1905. 



Distribution: Europe, except the extreme north, Asia Minor, south-western Asia 

 and Turkestan, southern Siberia, North America (introduced).

Of this species I have collected a couple of specimens in grassHgrown places on an 

 islet in the Yenisei, between Minusinsk and Ust Abakansk. The specimens taken do not 

 agree perfectly with any of the forms of this species described heretofore, one being a 

 form which seemed to be allied to Taraxacum privum Dahlst., the other a form alUed 

 to Taraxacum haemalopus Lindb. Owing to the scarcity of the material, new forms 

 based upon it, cannot be described. In flower and with young fruits at the beginning of 

 June. 



Distribution: The species extends over Europe and Asia, except the most northern 

 regions. Gradually strayed nearly all over the globe. 



Taraxacum Printzii Dahlst. nov. spec. [Tab. XVI].
