SEASHORE: SALT MARSHES, ETC 41 
and therefore divergent, they are hardly discernible ; they are 
Linch long and contain one perfect flower and a rudiment; glumes 
awnless, the empty ones rigid, both on the outer side; the flower- 
ing one as long, hyaline with a green nerve. Annual, flowering 
latter part of July, early August. 
Alopecurus bulbosus, the Tuberous Foxtail, is distributed locally 
around the coast of the southern half of England. It is very simi- 
lar to A. gentculatus, from which, however, it is distinguished by 
the basal internodes of the stems being swollen and bulb-like. 
Leaves very narrow, with prominent ribs, pale green. Panicle 
cylindric, tapering above, 1-2 inches long, dense but slender. 
Spikelets + inch long, 1-flowered ; empty glumes very acute and 
free, z.e. not cohering at the edges ; keel ciliate; flowering glume 
with a sub-basal awn twice its length; no palea. Perennial, 
flowering in June. 
Glyceria procumbens, the Procumbent Sweet-grass, is frequent in 
S.E. England, but rare in the north ; not recorded from Scotland, 
and doubtfully native in Ireland. Rootstock tufted, the culms 
numerous, 6-8 inches, prostrate or ascending. Leaves flat, sheaths 
inflated. Panicle compact, one-sided, with very short rigid dis- 
tichous branches, 2-3 at each insertion, never deflexed, glaucous- 
green. Spikelets } inch long, almost sessile, crowded, 4- or 
5-flowered ; flowering glume with a blunt scarious tip, the dorsal 
nerve sometimes slightly excurrent, forming a minute mucro. 
Annual or biennial, flowering June, July. 
Glyceria Borrert, Borrer’s Sweet-grass, is a very local species 
found on the south and east coasts of England, and in Ireland; it 
is intermediate between G. distans and G. procumbens ; but may 
be known by its much smaller spikelets, 34 inch long, which are 
wholly green, and by the dorsal nerve of the flowering glume ex- 
tending beyond the tip to form a minute mucro. The branches of 
the somewhat one-sided panicle are very short, 2-3 at each inser- 
tion, never deflexed. Perennial, flowering July, August. 
Spartina stricta, the Twin-spiked Cord-grass, occurs locally on 
the south and east coasts of England, growing plentifully where it 
is established. Rootstock extensively creeping. Leaves jointed 
to the sheaths and easily broken off, shorter than the spikes. 
Culms about a foot high, each bearing usually two, sometimes 
three, unilateral spikes which are erect and so closely contiguous 
as to appear like a single spike ; rachis prolonged to the tip of the 
uppermost spikelet. Spikelets 6-10 on each spike, half an inch or 
rather more in length, rigid, 1-flowered; empty glumes very un- 
equal, downy, the upper one mucronate ; flowering glume a little 
shorter than the longer empty one, I-nerved, awnless. Styles 
united for about half their length. Perennial, flowering in August. 
Spartina alterniflora, the Many-spiked Cord-grass, is abundant 
on the mudflats at Southampton. It is perhaps only entitled to 
rank as a sub-species. The leaves are not jointed to the sheaths, 
and are as long or longer than the spikes. Culms 2-3 feet each, 
bearing five or more spikes, not so close together as in the fore-
