TEMPERATE & ALPINE HIMALAYA & WESTERN TIBET, alt. 5-15,500 ft. 

 DISTRIB. Europe, N. Asia, N. Am. 



Stem 1-2 ft., erect, rigid or flaccid, smooth or scaberulous above, lower inter- 

 nodes hidden in the sheaths or nearly so, uppermost more or less exserted. Leaves 

 cauline 2-5 by -^ in., flat plicate or involute, firm or flaccid, erect or spreading, 

 smooth or minutely scaberulous above ; sheaths appressed, uppermost up to 4 in. ; 

 ligule truncate, up to % in., often erosely denticulate. Panicle lax, rigid flexuous 

 or flaccid, lowest branches solitary to 3-nate, slender, erect or spreading, aiperulous. 

 Spikelets loosely disposed, green or variegated; rachilla .smooth scaberulous or 

 pilose; gls. close or rather distant, firm or rather thin, I -^-i in., 3-nerved, keel 

 roughish, margins narrowly or broadly hyaline ; II rather longer and broader ; flg. 

 gls. -i in., subobtuse (or subacute in profile) upper -{ hyaline and sometimes erose, 

 nerves 5, slender, interspaces sometimes puberulous ; paled rather shorter. Anthers 

 -rV~T5 in. An extremely variable species in habit and length of ligule especially, 

 \\hich is usually short in European examples. The form with a long ligule forms a link 

 with P. attenuata, Trin. , which has usually a more contracted habit. Most of the 

 described varieties of nemoralis are also Indian.
