all the peduncles are very short and nearly quite simple, hut in 
moister situations many of them are as long as the spikelets. To us 
this species appears scarcely different from the last, except in being 
more glabrous : as in it, the summit of the larger glume is midway 
between its base and the summit of the third floret on the same side. 
Dr. Parnell remarks that when the outer glumella is opened out, its 
upper margins form an angle at the point, giving it a lanceolate or 
acuminate form, instead of being very obtuse as in B. mollis. 
9. B. mollis L. (soft B.) ; “ panicle close ovate erect in fruit, 
slightly branched, simple peduncles shorter than the crowded” 
or quite simple “ ovate somewhat compressed pubescent spike- 
lets, flowers closely imbricate,” midrib of glumes and glumellas 
downy, “ awn straight about as long as the florets, sheaths of 
the leaves pubescent or hairy. ” Watson : E. B. t. 1078 (good) :

or <?. 6. — In sandy ground in Devon and Cornwall, a form occurs 
with the leaves and spikelets densely pubescent, and all the peduncles 
quite simple and very short. Culm 1—2 ft. high. Panicle 2 — 3 inches 
long. Spikelets nearly erect. Florets5 — 10. Outer glumellas convex, but 
by no means forming such cylindrical florets as in the last two species. 
Apex of the larger glume half-way between its base and the summit 
of the third floret on the same side, sometimes a little longer, as in 
Dr. Parnell’s var. ovalis , tab. 117 (where the spikelets are shorter 
than usual), and sometimes reaching almost half-way to the summit 
of the fourth floret on the same side (var. pratensis, tab. 118). The 
glumes and outer glumellas are downy, but are not toothed on the 
midrib : in the last species they are scabrous although otherwise 
glabrous, but the midrib is toothed towards the summit. Parnell. 
[10. B. * arvensis L. (taper Field B.) ; “panicle spreading 
loose slightly drooping in fruit, lower peduncles much elongate 
simple or branched, simple peduncles longer than the linear- 
lanceolate compressed spikelets, florets imbricate in fruit,” 
inner glumella acute and as long as the outer one which is 
“shorter than the awn and with 2 prominent ribs on each side 
near the margin.” Watson : E. B. t. 1984 (glumes too narrow) :

not even naturalized. “This has longer peduncles than the 3 pre- 
ceding species, and the smallest glumellas, the latter resembling those 
of B. commutatus in acquiring the purple tinge, but differing in the 
prominent ribs or nerves on each side : ” Watson. Distinguished 
from B. commutatus by the inner glumella being acute and as long 
as the outer one, which has 2 prominent ribs near each margin. 
Apex of the larger glume reaching half-way from its base to the 
summit of the second floret on the same side. Awns rather longer 
than the glumellas, straight, slightly spreading when dry. Anther 
four times as long as broad.]
