cles about equalling the oblong compressed spikelets, florets at 1 
first imbricated afterwards distinct cylindrical, the incurved I 
edges of the outer glumella not overlapping those of the floret I 
above them, awn straight about as long as the floret, leaves I 
hairy but the sheaths nearly glabrous.” Watson in Hook.

— Culm 2 — 3 feet high. Known in fruit by its hairy panicle, and I 
separately rolled up flowers. Distinguished also from its allies by I 
“the apex of the larger glume being situated half-way between the I 
base of the glume and the summit of the second floret on the same I 
side and by having the outer glumella “ rounded on the upper 1 
half its length rarnell.

slightly drooping in fruit, lower peduncles often elongate and 1 
branched, simple peduncles equalling or exceeding in length I i 
the oblong-lanceolate spikelets, florets loosely imbricate,” 1 
outer glumella longer than the bluntisk inner one, “ when in I 
hairy.” Watson: Pam. Gr. tt. 124, 125. Serrafalcus Bab. I

its grayish-green usually glossy glabrous (sometimes downy) spikelets | 
acquiring a brownish tinge in sunny spots, its peduncles longer I 
and harsher than those of B. mollis and racemosus, and its glumellas 
larger and more inflated than in B. secalinus and arvensis: IVatson. 
Apex of the larger glume half-way (or a little more) between its base 
and the summit of the second floret on the same side. Inner glumella 
only reaching to the base of the awn, which is rather shorter than its | 
floret ; outer glumella when flattened, twice as long as broad. Mr. 
Baker finds in Yorkshire a meadow form, which has the spikelets quite 
separate, in fruit, as in B. secalinus. 
8. B. racemdsus L. {smooth B.) ; “panicle elongate erect 
in fruit, peduncles nearly simple about equal to” or shorter j 
than “ the ovate subcompressed glabrous spikelets, florets im- 
bricate compressed,” midrib of glumes and glumellas scabrous 
towards the apex, “ awn straight about as long as the glume, 
sheaths of the leaves slightly hairy. ” Watson : E. B. t. 1079 :
