This plant is very common in the Minusinsk district, in dry meadows, and the like, 

 and varies considerably as to stature, hairiness, breadth of the segments of the leaves, 

 size of the heads, colour, etc. I have observed it to be pretty common on islets in the 

 river Abakan, in several places in dry steppe meadows about Minusinsk, at Kushabar, Ust 

 Algiac, Ust Sisti-kem, Ust Tara-kem, and near the Dora Steppe. 



Resides the typical plant, I have found, in dry, sandy places on islets in the Yenisei, 

 near Minusinsk, and on the Abakan Steppe, specimens of /. setacea (Waldst. et Kit.) 

 Ledeb. 1. c. p. 532, a steppe form, especially distinguished by its dense pubescence, by 

 fihform leaf-segments, and smaller heads, measuring 3,5 — 4 mm. in length, and 2 mm. in 

 breadth. 



Distribution: Europe, the Caucasus, south-western Asia to Turkestan and the Hima- 

 layas, Siberia, northwards to past 70° north lat., eastwards to the Sea of Okhotsk, north- 

 ern Mongolia, Manchooria, China, and North America. The form setacea occurs in dry, 

 sunny places in middle Europe, the steppe region in eastern Europe, southern Siberia, 

 and northern Mongolia.
