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, wiUi narrower and not scarious-margined outer Israels. 



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

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

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

 Ust 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 Minusinsk and Kushabar; 

 in full flower in July. 



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

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

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

rhe Siberian specimens differ from the tj'pical 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 countiy being diffi- 

 cult to ascertain.
