512 7 THE GRASS FAMILY. [Anthoxanthum. 
The genus consists of but few species. t 
1. A. odoratum, Linn. (fig. 1167). Vernal Gena —A rather slender, 
erect perennial, 1 to 2 feet high, and quite glabrous. Spike-like panicle 
1§ to 2 inches long. Outer glumes very pointed ; the second about 3 
lines long, the first seldom above half that length. Intermediate and 
upper glumes usually quite included in them, or rarely the cigar awn 
slightly protrudes. 
In meadows and pastures, throughout Europe and temperate Asia, 
from the Mediterranean to the Arctic regions. Abundant in Britain, 
imparting a sweet scent to new-made hay. Fl. spring and early summer, 
and often again in autumn. [A. Puelii, Lecoq. and Lam., a native of 
southern and central Europe, has of late been introduced into several 
fields in England and Scotland, and may be recognised Me its very 
slender annual habit, and long, exserted awn. ] 
VI. PHALARIS. PHALARIS. 
Spikelets 1-flowered, broad and very flat, densely crowded into an 
ovoid or cylindrical spike or spike-like panicle as in Phlewm, but there 
are usually 6 glumes, the 2 outer ones, below the articulation, have the - 
keel projecting into a scarious wing, the intermediate pair small and 
empty, or one of them occasionally deficient, the upper pair, under the 
flower, flattened and complicate like the outer ones, but smaller and 
thinner, with the central nerve or keel short and scarcely conspicuous, 
or wanting in the inner one, which leaves it doubtful whether it be 
really a glume or a palea. 
A small genus, chiefly from the Mediterranean region and central 
Asia. 
1. P. canariensis, Linn. (fig. 1168). Canary Grass.—An erect, leafy 
annual, 2 to 3 feet high, with a densely imbricated, ovoid, spike-like 
panicle, 1 to 1§ inches long, variegated with green and white, and 
quite glabrous. Outer glumes very flat, 3 to 4 lines long, acute but 
not awned, white on the edges, with a broad green line down each 
side, the intermediate empty ones short and lanceolate. Upper glumes 
much shorter, narrow and pointed, smooth and shining, but usually 
villous, hardening round the seed as it ripens. 
A native of southern Europe or northern Africa, much cultivated as | 
Canary-seed in Europe, and frequently appearing as a weed of cultiva- : 
tion. In Britain, occasionally found as such. Fl. summer. [Another | 
species, P. paradoxa, Linn., is to be found entered into some British 
floras, but it has no claim to be considered even as a weed of cultiva- 
tion, being only a very rare and fugitive garden escape. | 
VII. DIGRAPHIS. DIGRAPHIS. 
A single species, often united with Phalaris, of which it has the 
rudimentary glumes immediately under the flowering ones, but it is © 
very different in inflorescence, and the outer glumes are not winged on =" 
the keel. E
