This subspecies may somewhat resemb- 

 le the Turkestan subspecies Regeliana in the 

 several, very densely and flowery spikes, but 

 is readily distinguished from the latter by the 

 shape of the perigynia. In our plant the 

 perigynium is H longer than the glume, 

 ovoid, drawn out above into a rather short 

 and broad, conical, generally shghtly oblique 



beak, membranous and obtuse at the orifice, ^'S- ^^- (^arex capillaris L. subspec. densi-
