(usually from half as long again to twice as long), straight in flower 
and fruit. Stamens 2, more rarely 3. 
In sandy places and by road- sides. Very local- Abundant on the 
Quenvais, more sparingly in St. Aubin's Bay, and at St. Clement's 
Jersey. 
Channel Islands. Biennial or Annual. Early Summer. 
The Jersey plant has the stems 1 to 2 feet high. Leaves 2 to 6 inches 
long, by ^ to | inch broad. Panicle rather dense, 3 to 8 inches long. 
Spikelets green, 1 to li inches long, exclusive of the awns. The 
florets about | inch long. Awns H to 2 inches long. Pedicels of the 
lateral spikelets much shorter than the spikelets. 
Keadily distinguished from B. ^ladritensis by its more lax and 
usually slightly secundly-drooping panicle, with much larger spikelets, 
which have their florets less separated in fruit and not at all curved ; 
the awns, also, are longer in proportion and never at all curved out- 
wards in fruit, so that the fruiting spikelets are regularly wedge-shaped, 
with straight sides, in B. maximus : while in B. Madritensis they are 
much wider at the apex and have concave sides. 
The Jersey plant belongs to a group of varieties or subspecies (I do 
not venture to say which) included under the name B. maximus. 
Our plant appears to be precisely the B. rigidus, var. ot, of Lloj^d, the 
B. maximus, var. a minor, of Grenier & Godron, and the B. ambigens 
of Jordan. B. rigidus of Both and Reichenbach is a distinct plant, 
doubtless the pubescent state of B. Madritensis.

Biennial or annual ? Stems rather stout, ascending or erect from a 
more or less geniculate or curved base. Leaves rather broadlv 
linear, more or less pubescent; slieaths split not more than one-third of 
the way down, cyliudriciil, minutely pubescent or subglabrous, the 
n[)permost one ofren wholly glabrous ; ligule prominent, about as 
long as broad, lacerate. Panicle secundly dr«x)ping in flower and fruit, 
large, nearly simple, very lax and open. Bachis with distant nodes, 
slightly scabrous, but not 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 (rarely \) spikelets. must of 
them much longer than the spikelets (exclusive of their
