extirpated by drainage. Lough Neagh, and other places in the 
county of Antrim. I/.. 6,7. — Culms — 3 ft. high. Leaves of 
the culm broad; of the barren shoots narrower, rigid, and convolute 
when dry. Panicle 1 — 4 inches long, at first spreading, afterwards 
compact. Hairs not half the length of the glumellas. The Irish 
plant is C. Lapponica of the 4th and 5th editions of this work, but in 
the true C. Lapponica Hartm., the glumes are described as I-nerved, 
the awn is bent, and the hairs are scarcely shorter than the glumellas. 
14. Agrostis Linn. Bent-grass. (Tab. VL f. 13.) 
Panicle loose. Spikelets laterally compressed. Glumes 2, 
acute, membranous, longer than the floret, awnless. Floret 
sessile, glabrous or with 1 — 2 tufts of very short hairs at the 
base. Glumellas 2, unequal ; the inner sometimes wanting, the 
outer with or without an awn. Caryopsis free, oblong, or linear. 
— Name; given by the Greeks to grasses, from a-ypog, a field, 
because they are so abundant in open places. 
* Upper glume the smaller. Neuter floret 0. 
1. A. canina L. ( brown B.) ; branches of the panicle long 
slender erecto-patent, glumes unequal lanceolate rough on the 
keel, outer one 1 -nerved, outer glumella erose at the end 5- 
nerved the middle nerve terminating below the middle at the 
insertion of the dorsal awn, inner wanting (or very minute ?), 
leaves linear, sheaths smooth, ligule oblong acute. E. B. t. 
1856 : Pam. Gr. t. 15. 
Moist heaths and moory places, abundant. If.. 6, 7.— Very vari- 
able in the size and colour of its flowers, purple or green, and in the 
length of the dorsal awn, which is sometimes included within the 
glumes, at other times considerably exserted. We have never seen 
more than one glumella, not even the rudiment of a second ; but, as 
in the next species, Smith and Leers have detected an inner one. 
2. A. setdeea Curt. ( Bristle-leaved B.) ; branches of the pani- 
cle short close spreading in flower, glumes unequal lanceolate 
rough on the keel, outer glumella erose at the end 4-nerved 
with a long geniculate twisted awn from its base, inner very 
minute, leaves setaceous, sheaths rough, ligule oblong acute. 
E. B. t. 1188 : Pam. Gr. t. 83. 
Very local, almost wholly confined to the dry downs of the extreme 
south and south-west parts of England, as Hampshire, Devonshire, 
and Cornwall. 2/.. 6, 7. — Larger glumella white, thin, and mem- 
branous, truncate at the top, with 4 green nerves, of which two, the 
lateral ones, project into mucros : its awn from the very base, rough, 
truly geniculate and twisted ; inner one very small, truncate and 
toothed, accompanied on each side at the base by a tuft of white hairs. 
3. A. vulgaris With. ( fine B.) ; branches of the panicle 
smoothish its branchlets spreading after flowering, glumes nearly
