England. Perennial. Early Summer. 
Extremely similar to A. geniculatus, but with the base of the stems 
swollen into' bulblike corras. The lower joints of the stem are never 
rooting, the stem is more slender and usually less geniculate, and the 
upper leaf commonly much further from the panicle than in A. ge- 
niculatus. The leaves are narrower and have more prominent nerves 
than in A. geniculatus, and are commonly channelled. The panicle, 
which is f to 2 inches long, is more slender and more fusiform than 
that of A. geniculatus ; the spikelets are narrower, but rather longer 
(I inch). The glumes are much more acuminate, shortly mucronate, 
and are clothed with fewer and shorter hairs the keel and ribs on 
the glumes have long hairs, at least in the lower part, but not so long 
as those on the keel of A. geniculatus. 
I have never gathered A. bulbosus, but Mr. F. Stratton has sent 
me numerous fresh specimens from Brading, Isle of Wight, some of 
which 1 have in cultivation. 
I am still in some doubt if A. fulvus, A. geniculatus, and A. 
bulbosus ought to be considered merely as subspecies of one super- 
species. Dr. Bromfield, in " Phytol.," ser. i. vol. iii. p. 1080, says, 
" I cannot rid my mind of the impression that A. bulbosus and fulvus 
are but states or perhaps permanent varieties of A. geniculatus, much 
as I should wish to be convinced to the contrary by the many and 
able botanists who still keep them apart." And the Messrs. Paget, 
in the " Nat. Hist, of Yarmouth," say of A. fulvus, geniculatus. and 
bulbosus, that they may be traced mto one another by the closest 
and most regular' gradations." I quote the last remark from the 
" Cybele Britannica," not having access to the above-named work.

Perennial. Rootstock oblique with very short stolons. Stem not 
geniculate, erect, not rooting at the base, simple. Leaves thin, with 
numerous slightly prominent slightly rough ribs, {:a-e green, scarcely 
glaucous; ligule short, blunt. Panicle broadly fusiform-cylindrical, 
abruptly rounded at the base and apex, broadest about the middle ; 
panicle-branclies with 3 to 8 spikelets. Spikelets narrowly oblong- 
elliptical. Glumes united at the base for about one-fifth to one-fourth 
ot their length, converging at the tips, gradually acuminate and acute,
