points, not awned, as long as the florets, glabrous, usually pubescent at 
the apex, and frequently ciliated with long soft haire on the keel and 
lateral margins near the apex. Lower pale linear— lanceolate, acumi- 
nate, shortly mucrouate but not awned, densely pubescent with short 
hairs. 
On sandy sea- shores and on dunes amongst loose sand. Rather rare. 
Possibly in Devon and Dorset and South Wales, and certainly from 
Essex and North Wales northward to Orkney and Shetland. Rare 
and very local in Ireland, where it is chiefly found on the north 
coast. 
England, Scotland, Ireland. Perennial. Late Summer. 
Plant growing in large roundish tufts, beyond the circumference of 
which the barren tufts of the stolons come up singly. Leaves 6 inches 
to 3 feet long by | to f inch broad. Stems 2 to 4 feet high, inclining 
towards the circumference of the tufts. Spikes (J inches to 1 foot long, 
straight or slightly arched. Spikelets f to 1 inch long. Florets f to 
1 inch long, 
Elymus geniculatus, Curtis, which was alleged to have been found by 
Dickson near Gravesend, but which is now known only as a cultivated 
plant, resembles E. arenarius, but has the rootstock far less creeping, 
and the stolons so short that their barren shoots come up close to 
the parent tufts. The leaves are about half the breadth of those 
of E. arenarius. The spike is not so dense, and the spikelets in 
the middle of the spike are rarely more than 2 together, and the 
upper ones are often solitary. The glumes are subulate, glabrous, 
and much longer than the florets. Spikelets 1- or 2 -flowered. The 
lower pales are subulate, shortly pubescent. The bending of the spike, 
relied on as a character, is apparently a monstrosity : out of more 
than two dozen plants raised from seed by me not one had the spike 
geniculate.

Spikelets quite sessile, or the lateral ones shortly stalked, in threes, 
very rarely in pairs, at each node of the racfiis, arranged in a simple 
spike, usually open during flowering, each containing a sinjxle perfect 
floret, with a stalk-like rudiment above it, or only the central floret of 
each triad containing a perfect floret, the lateral ones being male, or 
the two lateral spikelets with a perfect tioret in each, and t"he central 
one commonly male or neuter. Ghifues "2, both on the side of the 
spikelet turthest from the racliis, about as long as the floret, pointed
