with the following; see N. Beitr. Ill, 25 asper Murr. 2512. 
— Lower branches of the panicle 2 together, very diver¬

looser; stem often taller; Is broader; flowering period

above Chillon in company with the last! and probably 
in many other places . ramosus Huds. (1762). 2512.b*) 
4. Ls folded during aestivation, the rad. narrower than the 
caul., long-ciliate. Lower glumella with a short awn.— 
Pasturages, road-sides; everywhere. 6 erectus Huds. 2513. 
— Ls rolled up during aestivation, fairly equal in width, 
glabr. Lower glumella unarmed or short-mucronate.—

Orbe? (a single specimen in 1885!). 6 inermis Leyss. 2514. 
5 (2). Panicle very loose, the branches drooping on almost 
every side; branches very rough; spikelets with awns

road-sides; everywhere. 5 sterilis L, 2515. 
— Panicle fairly dense, drooping on one side, the branches 
smooth. Spikelets shorter, soft pubescent. Stem 20—30cm. 
b . fioridus Grml. (glabratus Sond.?) Stem taller; spike¬ 
lets more numerous, glabr.—As the last, but not every¬ 
where (wanting in B. L.); sometimes adventitious; 
b. Wall., Wilchingen, Diessenhofen. 5 tectorum L. 2516. 
6 (lj. Sheaths of the ls furrowed, glabr., rarely with scat¬ 
tered hairs. FL, when mature, contracted at the edges, 
cylindric and distant. Type of B. secalimis . . 7 
— Sheaths of the ls, at any rate the lower ones, hairy. FIs, 
also at maturity, imbricate, covering one another, at 
any rate by the base ...... 8 
7. Spikelets 15—20 mm, glabr. (not hairy) or rough. Awns 
slender, undulated-flexible.—Among corn; distrib. 6
