Leaves filiform, conduplicate, mth a few prominent lines beneath, 
flaccid, nearly smooth, pale glaucous green. Ligule of uppermost 
leaf linear-lanceolate, very acute, lacerate, five or six tinies the 
diameter of the stem opposite to it. Panicle drooping at the summit. 
Pedicels of the lateral florets thickened upwards, shorter than the 
spikelets. Second floret usually longly stipitate, the portion of the 
axis between the two being often equal to half the length of the 
second spikelet. 
In wet turfy bogs. Apparently local, but probably widely dis- 
tributed. Fleetpondnorth, Hants; Woking Common, Surrey; Stratton 
Heath (?) and Cawston Decoy, Norfolk. Forfarshire; "Loch of 
Drum," Kincardineshire, " Loch Connor, Aberdeenshire," Dr. J. Roy. 
Near Clifden Roundstone and Kilkieran, Connemara. 
England, Scotland, Ireland. Perennial. Summer. 
Very near A. eu-flexuosa, but the radical leaves are longer (3 to 8 
inches), more slender, not semicylindrical, but folded into a gutter, 
and very glaucous ; the ligule of the uppermost stem leaf is five or six 
times longer and verv acute; the panicle is usually longer, sometimes 
5 or 6 inches ; the spikelets are I inch long, more numerous and more 
racemose; the second spikelet usually more longly stalked; the 
glumes more nearly equal, paler, and sooner becoming of a' dull 
yellowish-olive ; the awn longer in proportion to the pales and glumes 
than in A. eu-flexuosa. 
From Dr. Trimen's notes in the " Journal of Botany," referred to 
above, it seems probable that Hudson, in the first edition of " Fl. 
AngHca," had this plant in his mind when he described his A. setacea, 
but in his second edition he referred his A. setacea to A. montana 
Linn., and by the localities he stated for it, he certainly confused 
A. uligino>a with forms of A. eu-flexuosa. Dr. Trimen, however 
contends that the name " A. setacea " ought to be revived. ' 
_ The practice of raking up an obsolete name is alwavs hi<rbly objec- 
tionable, and the obsolete in the present case is not likelV to be adopted,
