Perennial. SubcEespitose or scarcely cjDspitose. Rootstock with 
creeping branches, terminating in tufts of numerous barren stems or 
barren shoots and flowering stems, and with autumnal or hybernal 
stolons terminating in barren stems. Stems erect, unbranched, op 
branched at the base. Leaves firm or rather firm, broadly linear, 
tapering from below the middle to the apex, very acute, with nume- 
rous nearly equal greatly elevated ribs, and scabrous margins, yellow- 
ish green, often with a glaucous tinge, hairy with short hairs, or 
subglabrous ; sheaths glabrous, or pubescent with short reflexed 
hairs ; ligule subquadrate, obtuse. Spike simple, rather lax or dense, 
erect or very slightly arching-drooping. Spikelets diverging from 
the rachis, at first linear-cylindrical-fusiform and acute, ultimately 
elliptical-linear, 7- to 20-flowered, glabrous or more or less pubes- 
cent. Inner glume about half the length of the contiguous floret, 
acute or mucronate, 7-ribbed. Lower pale abruptly acummate and 
subacute, 7-ribbed towards the apex. Awn shorter than the pale, 
usually not half as long, and frequently reduced to a mere mucro. 
LTpper pale as long as and broader towards the apex than the lower 
Yar. a, glabrescens. 
Spikelets glabrous. 
Yar. /3, puhescens. 
Spikelets more or less finely pubescent with short hairs. 
On downs and in pastures, especially in chalky or limestone districts. 
Rather local, but frequent in the south and east of England, reaching 
north to Yorkshire. It has been reported from both Scotland and 
Ireland, but there is little doubt B. sylvaticum has been mistaken 
for it. 
England. Perennial. Summer. 
Stems 9 to 30 inches high. Leaves of the barren shoots 2 inches
