incli broad. Panicle 2 to 5 inches long. Spikelets 1 to Ij, exclusive 
of the awns. Florets about ^ inch, exclusive of the awn. 
In var. 0 the panicle, in the specimens I have seen, is not above 1^ 
to 2 inches, exclusive of the awns, and the panicle-branches are much 
shorter and fewer. Possibly it ought to be considered a distinct sub- 
species, but I have never seen it alive, though I have looked carefully 
for it both in Jersey and Guernsey. In habit it approaches B. fas- 
ciculatus, Presl. 
Upright-annual Brome- Grass.

Biennial or annual ? Stems stout, ascending from a more or less 
geniculate or curved base. Leaves rather broadly Hnear, more or less 
pubescent ; sheaths split half way down, cylindrical, pubescent; 
ligule prominent, about as long as broad, lacerate. Panicle at first 
siiberect, afterwards more or less secundly drooping, rather large, 
nearly simple, rather dense and contracted, or lax and open at least in 
flower. Rachis with distant nodes, rather thinly setosely-pubescent 
(or in Continental forms densely pubescent). Panicle-branches 2 to 
6 at the lower nodes of the rachis, rarely bearing more than a single 
spikelet, sometimes 1 or 2 of them with 2 or 3 spikelets, and (in the 
Jersey plant) most of them shorter than the spikelets, or several 
of them as long as the spikelets (exclusive of their awn), ascending- 
spreading or spreading in flower and fruit, or suberect in fruit, more 
or less setosely-pubescent like the rachis. Spikelets erect or slightly 
drooping, linear-eHiptical before flowering, oblong and enlarged up- 
wards during flowering, and ultimately oblong-wedge-shaped, with 
straight sides, 4- to 12-flowered. Glumes lanceolate-subulate, very 
acute, almost awned, broadly scarious on the margins, the upper one 
one-fourth to one-third longer than the lower and 3-ribbed, the lower 
one 1- or 3-ribbed. Florets slightly overlapping, not diverging or at 
all curved outwards in fruit. Lower pale linear-lanceolate-subulate, 
deeply bidentate, with 2 long apical teeth about one-eighth the length 
of the pale, with broad so.-irious margins and aj)ices, with 7 rather 
prominent and nearly equidistant ribs, scabrous-pubescent. Awn 
from the bottom of the notch of the pale, longer than the pale
