The specimens coUecled vary between 25 and 35 cm. in height. The leaves narrow, 

 2 to 2,5 mm. broad, and 4 to 8 cm. long, conduplicate, so as to give them an appe- 

 arance of being only about 1 mm. broad, always completely entire, with short, 

 appressed hairs. The pedicels 2 to 4 mm. long, only about half the length of the calyx. The 

 whole plant of a hght yellowish green. Rather common on the Abakan Steppe, espe- 

 cially in open, grass-grown places, on mountain slopes, etc., where to be met with in full 

 flower, here and there already past flowering at the beginning of June. 



Distribution: The Caucasus (on Mount Elbruz up to 8000 ft. above sea-level), Rus- 

 sian Turkestan, southern Siberia, from the government of Tomsk to Trans Baikal, north- 

 ern Mongolia.

Scattered on the Abakan Steppe and in its environs, in dry, grass-grown places,

 leaves. In the Urjankai country I have found the species near the Kamsara.
