— Lower glumella distinctly longer than the upper .9 
9. Awn inserted below the top which is deeply 2-fid, finally 
or, when dry, often spreading-divergent. (Panicle 
drooping) . . . . . . . . 10 
— Awn inserted higher, below the top which is shortly 
2-fid, erect or slightly curved outwards . . 11 
10. Panicle (in a normal pi.) compound. Spikelets lanceo¬ 
late, 20 mm. FIs gen. separated at maturity, only cover¬ 
ing each other quite at the base. Distinguishable from 
B. arvensis by its panicle drooping more decidedly on 
one side, its spikelets more compressed, and its anthers 
shorter.—Fields, rare and perhaps only introduced; 
Aargau (Bremgarten!), Neuchatel, Aubonne. 5,6 (earlier 
than 2519).patulus M. K. 2520. 
— Panicle gen. racemose (branches bearing 1 spikelet). 
Spikelets oblong-lanceolate, 25—40mm. FIs covering 
each other to a considerable extent when mature, glabr. 
or (y. villosus) hairy.—Arid, sandy places; T. W. V.; 
sometimes also adventitious in other places. 5 
squarrosus L. 2521. 
11. Panicle erect after flowering, contracted. Spikelets oval- 
oblong, gen. soft-pubescent. FIs dense; lower glumella 
strongly nerved. Stem covered above with numerous 
spreading hairs.—Uncultivated places, road-sides; every¬ 
where. 5 . . . . . . * mollis L. 2522. 
— Panicle more or less drooping after flowering, sometimes 
also almost erect in 2523. Spikelets gen. glabr.; fls 
rather less dense; lower glumella faintly nerved. Stem 
glabr. above. Type of B. racemosus . 12 
12. Spikelets (15—20 mm) oblong-oval, composed of 5— 6 fls. 
Lower glumella almost regularly rounded at the edges. 
— Fields, grassy places, road-sides; localities still to be 
verified on account of the general confusion with the 
following. 5, 6 .... racemosus L. 2523. 
— Spikelets (20—30mm) oblong-lanceolate, containing 6 to 
8 fls, more acute than in the last. Lower glumella en¬ 
larged above the middle of the edge in an obtuse angle 
(as in 2522). Panicle rather looser, and with finer 
branches than in the last.—As the last (common, at 
any rate, in Canton Vaud). 5, 6 commutatus Schrad. 2524. 
657. Brachypodium. False Brome. Ill, 21. 
1. Awns of all the fls shorter than their glumella. Ls 
rather stiff. Rt-stock creeping. Spikelets hairy or (v. ru- 
pestre) glabr.—Thickety hills, wood-edges; distrib. 6 
pinnatum R. Br. 2525.
