(A. seta'cea. Awn incurved from near the base of the blossom; 
inner valve minute: calyx lanceolate, tapering, rough : radical 
leaves bristle-shaped : stem nearly erect: panicle close, oblong. 
Curt. 12— E. Sot. 1188. 
j Root rather woody, tufted, with strong downy fibres. Stems eight to 
twelve inches high, a little inclining. Leaves pale glaucous green; those 
of the stem with very long smooth sheaths. Stipula tender, often torn. 
Panicle erect, but little spreading; its branches angular, bristly. 
Flowers erect, pale purplish. Calyx of two unequal, scarcely awned 
valves, downy. Outer valve of the Bloss. lanceolate, shorter than the 
calyx, with a rough twisting awn, twice the length of the valve. An* 
thers purplish, deeply cloven at each end, prominent. Styles distinct.

Bristle-leaved Bent Grass. A. setacea. Curt. Hook. A. alpina. With, 
ed. 6. On dry, turfy heaths, in the south and west of England. Curtis, 
who first distinguished this grass, received it from Piddleton Heath, 
Devon. It abounds in Cornwall. On Bagshot Heath. Curtis. Moors 
in Yorkshire. On the downs in Dorsetshire, and the higher part of the 
New Forest. P. June—July. E.) 
A. PAbus r TRis. Calyx husks equal: blossom outer valve twice the 
length and breadth of the inner: awn straight, much shorter 
than the blossom, fixed a little beneath its point. 
Straw nearly smooth, creeping and sending out fibrous roots and branches 
from the joints as in A. stolonifera. Leaves broad, very rough, those oil 
the stem from four to five inches long, very taper-pointed; those on the 
branches shorter. Sheaths rough. Sheath-scale long. Panicle six inches 
long, branches half to two inches, spreading, the longer ones bare at the 
base, the shorter ones crowded with florets down to the main fruit-stalk. 
Calyx , husks equal, both serrulated on the keel, the inner only on its 
upper half. Blossom one quarter shorter than the calyx, outer valve, 
with a short awn, fixed beneath its point; inner valve but half the 
length and breadth of the outer. Awn two-thirds the. length of the outer 
valve of the blossom, and fixed half its own length below its point. 
(Marsh Bent Grass. Welsh: Meus-wellt y gors. E.) Specimen from 
Dr. Goodenough, who considers it an awned var. of the A. alba palustris 
of Huds. (Mr. Sinclair has proved that it retains its characteristics 
when raised from seed; and states that its properties and structure 
differ more from the other varieties of A. stolonifera, than those do from 
each other. In moist woods, supported by bushes, it attains the height 
of five feet. E.) 
In swamps and moist ditches. Rev. Dr. Goodenough. 1 P. June—July.* 
A. pal'lida. Calyx valves unequal; blossom inner valve hair-like, 
very short: awn somewhat longer than the blossom, fixed below 
its middle. 
PLATE XXII. 
About eighteen inches high. Straws smooth. Root-leaves bristle-shaped, 
rather rough. Stem-leaves much broader, flat above the sheathing part, 
and roughish. Sheath-scales long, pointed. Panicle a delicate pale green, 
about three inches long. Branches from half to one inch, but little 
* (It is inferior to either var. of A. stolonifera, and can only be considered as a weed, 
choking up drains and underwood, Hort, Gram. E.)
