AMONG THE WILD FLOWERS. 229 
sandy sea-shores. My specimens are from 
Dorset and Guernsey. In muddy salt-marshes 
or flats are the two species of Spartina ; a very 
rare species, J/zéora, in pastures near the sea; 
Phleum arenarium, the Sand-hills Cat’s-tail, 
and Tritecum gunceum, Sand-hills Wheat-grass, 
are found commonly growing with Psamma or 
Ammophila, the tall, rigid grass called Sea- 
reed, or Sea-bent, with straw-coloured panicle, 
whose roots bind the shifting sands ; Hordeum 
maritimum, Sea-barley, is common ; Alopecurus 
bulbosus, a species of Foxtail, forms ovate 
fleshy knobs at the lower knots of its stem. 
There is also Corynephrous canescens, or Aira, 
its spikelets varied with purple and white ; the 
two species of Polypogon, one of them, P. mon- 
speliensis, having beautiful silky panicles; several 
species of Sclerochloa, or Glyceria, by some 
classed with Poa; and the two species of 
Elymus, Lymegrass, one of which, £. genzcu- 
latus, has its spikes bent downwards at the 
second or third spikelet; all these belong to 
the sea. 
Then there is a group which is attractive 
rather for curiosity than for any other feature, 
Triglochin maritimum, Potamogeton flabellatus,
