Specimens referred to this form by me, have been collected on the banks of the 

 Bei-kem, near Ust Sisti-kem. The form differs from the preceding one in having the 

 spikelets more pointed at the summit, and longer, from 4 to 5 mm. long, generally 

 placed singly, or in pairs. Nearly past flowering at the beginning of August. 



Distribution: Europe, except the arctic and' extreme southern portions, south- 

 western Asia, Siberia, northern Mongolia, eastern Asia, North America.

Of very common occurrence on the liorders of the saliferous marshes on the 

 Abakan Steppe, where taken flowering by me in the middle of June. The head consists 

 of from 2 to 5 spikelets, most commonly 3, rarely 2, or, at times, even of 1 spikelet (f. 

 nwnoslachiius G. F. W. Meyer, 1. c). The spikelets are to 1,8 cm. long, commonly 

 from 1,2 to 1,5 cm. The glumes are always distinctly, densely and shortly pubescent, 

 and with a far projecting dorsal nerve, of a rather light yellowish or green colour. The 

 number of the stigmas always 2. The specimens collected are all comparatively 

 slender, with culms from 30 to 50 cm. high, and with rather narrow leaves, to 3 mm. 

 broad. 



Distribution: Nearly all over the globe, except the extreme northern regions.
