 acute or almost awned, ovary glabrous.

 land ; Ireland ; Channel Islands ; fl. June-July. Rootstock creeping, stoloni- 

 ferous. Stems 2-6 ft., nodding, smooth. Leaves J-J in. broad, smooth, 

 striate. Panicle 3-6 in., contracted after flowering; rachis 3-quetrous, 

 smooth; branches 2-nate, scabrid. Spikelets many, |-| in., linear-oblong, 

 green and dull purple ; empty glumes broadly hyaline ; fl. glumes scabrid 

 above, rarely awned ; margins hyaline. DISTRIB. Europe (Arctic), N. 

 Africa, W. Siberia, Himalaya, N. America. A large maritime state with 

 rougher sheaths and branches of panicle divaricate after flowering is the

N. England ; Ireland ; fl. June-July. Perhaps only a sub-species of 

 F. ela'tior, but smaller, less stoloniferous ; panicle much narrower, more 

 distichous and simple, sometimes 10 in., branches shorter, in pairs, one 

 with 1 spikelet, the other with 2 or more ; fl. glumes more numerous, some- 

 times shortly awned. DISTRIB. Europe (Arctic), N. Asia ; introd. in 

 N. America. 



F. lolia'cea, Curt, (not Huds.), with inflorescence racemose or spiked, spikelets 

 distichous, awn 0, fl. glumes more obtuse, is a hybrid with Lol'ium peren'ne.

 scabrid, awn double their length, ovary glabrous. JBromus, L.

 fibrous. Stems 2-4 ft., smooth, terete, nodding. Leaves flaccid, f-J in. 

 broad, bright green, striate, scaberulous above ; sheaths smooth. Panicle 

 8-12 in. ; branches in pairs, and 3-quetrous rachis long slender scabrid. 

 Spikelets % in., linear-ovate or -oblong, membranous, pale green ; empty 

 glumes lanceolate, broadly hyaline ; fl. glumes 2-fid. awn variable, very 

 slender, flexuous ; styles subterminal. DISTRIB. Europe, Siberia. Flowers

** Leaves involute ; ligule of upper sheath long, not auricled, 



4. F. sylvat'ica, Vill. ; panicle open subsecund erect, fl. glumes 3-5 

 acute scabrid, top of ovary hairy. F. Calama'ria, Sm.
