truncate and suddenly cut off, and, besides, pubescent at the margin. The glumes are 

 broadly scarious-margined and rough — especially so along the keel, which is nearly 

 slightly prickly — and 3-nerved, of which the midmost one, the dorsal nerve, projects 

 into the short awn. The length of the florets is, to some extent, varying, being roughly 

 from the same as that of the glumes to about Va shorter. 



From the steppes of southern 

 Russia I have seen specimens of 

 Phleum Boehmeri subspec. laeve 

 (M. BiEB. spec!) which, in the struc- 

 ture of the glumes, shows some 

 approach towards this one; the glu- 

 mes in this subspecies are, however, 

 glabrous or nearly quite so. Our 

 plant is, for the rest, of the same 

 structure as the typical species. 



Rather common in dry meadows, 

 on hot, stony slopes etc., on the Aba- 

 kan Steppe, and on the islets in the 

 Yenisei and Abakan. Young, unblown 

 flowers in the middle of June. All of 

 the specimens collected belong to 

 subspec. decurlatum. 



Distribution: Temperate portions 

 of Europe and Asia.

The species varies rather much in the dimensions of the panicle, the length and 

 hairiness of the spikelets, and in the breadth and length of the leaves. Collected flowering 

 in June. Rather frequent on grass-land on the islets in the rivers Yenisei and Abakan, 

 and also at Ust Sisti-kem, near the Bei-kem, and at Ust Tara-kem. 



Distribution: Europe, except the extreme south-eastern portions, south-western 

 Asia, Siberia, Mongolia, Japan.
