Leaves half the length of the strawy rather flaccid, sheathing the stem 
higher up than in the other varieties. 
In shady places. FI. Brit. E.) 
A. canes'cens. Leaves like bristles; sheaths rough; flowers in a 
panicle; awn not longer than the calyx. 
( E.Bot . 1190. E.)— Plate XXIV — FI. Dan. 1023; hut the panicle much 
larger and more expanded than it grows with us — Lob. Adv.Alt. 466. 1—- 
J.B. ii. 463. 2. 
Awns encompassed with little teeth in the middle part, brown and thick 
below, but whitish, slender, and somewhat club-shaped above. Paler 
than most other grasses; which distinguish it at first sight. Linn. No 
plant alters its appearance more completely when cultivated than this, 
growing much larger, quite upright, and losing entirely its grey colour. 
Woodw. From four to six inches high. Root-leaves very slender. Stem- 
leaves broader. Panicle spike-like, purplish, one and a half inch high, 
half an inch broad. Calyx husks unequal; (PI. 24. a.') Awn the length 
of the shorter husk, nearly twice as long as the blossom. The struc¬ 
ture of the awn is remarkable, the lower half is thicker, opake, and yellow 
brown, the upper half very fine, whitish, semi-transparent, fixed to the 
centre of the broad top of the opake woody part, which is encompassed 
with very minute teeth. (PL 24. c.) ( Anthers purple, giving a cast of 
colouring to the panicle. E.)

A. prje'cox. Leaves like bristles ; sheaths smooth, angular with fur¬ 
rows ; panicles spike-like ; awn nearly twice as long as the calyx.

From two to five inches high. Spike-like panicle one to one and a half inch 
long, less than a quarter of an inch broad. Blossom valves cloven at the 
end, nearly as long as the calyx. Awn in structure similar to that of 
A. canescens , but wants the broad top to the lower opake part. Sufficiently 
distinct from A. canescens , and flowers earlier. 
Early Hair Grass. (Welsh: Brigzoellt y gwanwyn. Common dry gra¬ 
velly soil. A. May*—June. E.) 
A. caryofhylle'a. Leaves like bristles; sheaths smoothish, furrowed; 
panicle wide spreading when ripe; (triple forked: E.) awn 
taller than the calyx.

Varies very much in size, from two to twelve inches high. Panicle few- 
flowered ; close whilst in flower, widely expanding when in seed. Blossom 
shorter than the calyx. Awn twice as long as the blossom, fixed below 
its middle, yellow and opake in the lower, paler and finer in the upper 
part. The larger plants somewhat resemble A. Jlexuosa, but want the 
zigzag fruit-stalks (sometimes slightly so. Sm. E.) and the woolliness 
at the base of the blossom. The smaller plants may be distinguished 
from A. prcecox by the panicle expanding when ripe, and by the awn 
being less than twice the length of the calyx. It is, moreover, an annual 
plant.
