This species, no doubt, belongs to the group of Dissimilia, separated by Dahlstedt, 

 from which, however, it may be easily distinguished by the paler colour of its leaves, its 

 involucre of a lighter green, with narrower and not scarious-margined outer bracts. 



In meadows and grass-grown places on islets in the Lower Abakan, where collected 

 in full flower and with ripe achenes in tlie early days of June.

Scattered in and about cultivated fields on the Abakan Steppe, near Askys and at 

 list Kamuishto, where I have collected it with quite young heads in June. I have also 

 found it to be pretty common on the borders of fields between Mnusinsk and Kushabar; 

 in full flower in July. 



Distribution: The species has been carried about with cultivated plants, and is now 

 to be fovmd as a troublesome weed over the temperate and subtropical regions of the old 

 and new world. Thus, it is difficult to ascertain its native country.

The Siberian specimens differ from the typical form by being completely glabrous 

 (f. uliginosus). As a weed near habitations, such as Askys and Ust Abakansk, and in 

 fields between Minusinsk and Kushabar. 



Distribution: A cosmopolite, like the preceding one, its native country being diffi- 

 cult to ascertain.
