ribs, leaves and sfieaths pubescent. E. B. t. 1030: Pam. Gr.

Waste ground, fields and hedges ; common. Q. 6. — Culm 2 feet 
high. Remarkable for its long, narrow, much-awned, and drooping 
spikelets. 
4. B. Madritensis L. ( upright annual B.) ; panicle erect 
slightly branched, spikelets linear-lanceolate, florets remote 
subcylindrical subscabrous about as long as the straight awn 
diverging during and after flowering, outer glumella 7-ribbed 
; scarcely longer than the inner one, rib on each side of the dor- 
sal one obscure the two marginal ones approximate, lower sheaths 
with hairs pointing downwards. — a. stem glabrous, rachis and 
I pedicels scabrous. B. diandrus Curt.: E.B. t. 1006 : Pam.

Rare, on sandy barren wastes, principally in the south of England. 
About Edinburgh and coast of Fife, Scotland (occasionally). ©. 
6, 7 One foot high. Stamens usually 2 but sometimes 3 ; hence 
we have reverted to the name originally given to this species. Allied 
to B. sterilis ; but the panicle is smaller, erect, or erecto-patent, often 
purplish. From this, B. tectorum (introduced at Hoddesdon, Hert- 
fordshire) is principally distinguished by the unilateral drooping 
panicle, and the outer glumella much longer than the inner one. 
5. B. mdximus Desf. ( great B.) ; panicle erect lax ultimately 
drooping slightly branched, spikelets lanceolate downy long- 
stalked after flowering, florets remote subcylindrical downy 
about half the length of the straight awns diverging during and 
after flowering distinctly 7-ribbed, outer glumella of the lowest 
floret equal to the larger glume, leaves downy on both sides.

On the sands of St. Aubin’s Bay, the Gieve d’Azette and the 
Quenvais, Jersey. ©. 6,7. — Stamens often only 2. Distinguished 
by its long awns, the larger glume being as long as the adjacent 
glumella, the conspicuous equidistant 7 nerves to the glumella, and 
“ by a sharp conical point at the base of the florets:” Parnell. 
** Lower glume with 3 — 5, upper with 7- — 9 nerves. Florets oblong, 
turgid, erect. Serrafalcus Pari. 1 
f Outer glumella 7-nerved.

1 Mr. Bentham considers that all the members of this group (with, perhaps, the 
exception of B. squarrosus) form only one natural species, B. arvensis. There 
are certainly too many artificial ones. Dr. Schultz proposes to unite our 6, 7, 8, 
while he distinguishes B. mollis by the sheaths and leaves being furrowed with 
elevated nerves.
