The lower pale is 8 — 9 mm. long, the upper one 

 only K' to % as long as the lower one. It is especially 

 the structure of the glumes and the great difference in 

 the size of the 2 pales by whicb this form is charac- 

 terized. But, on account of the scarce material I have 

 had at my disposal, I cannot express any opinion on the 

 constancy or systematic value of these characters. Each 

 spikelet generally contains 4 florets. On sandy soil on 

 the Abakan Steppe, near Askys, and in the neighbour- 

 hood of Ust Abakansk, and also in the Urjankai country 

 on the rivers Sisti-kem, Tara-kem, and Kamsara. Scat- 

 tered on the steppes on the Ulu-kem. 



Distribution: Southern Europe, western Asia, southern Siberia eastwards to Trans 

 Baikal, northern Mongolia.
