 plicata of Fries ; the other with the panicle nearly simple and unila- 

 teral, rachis smooth and thespikelets nearly as large as in a. (where the 

 outerglumella is more than twice as long as broad,) which is G. pedi- 

 ce/Z^^a, and is intermediate between the true P. Jluitans and plicata To 

 those readers who rely on such points, and on the form and colour 

 of the anthers, for characters, there must be at least six or eicrht va- 

 rities or species [m this country and as many, though not quite the 

 same, m N. America.

Sea-coast, frequent. 2^. l.~ Culms 8-15 inches high, rigid, 

 glaucous. Lower branches of the panicle usually in pairs, but some- 

 times S—5 in luxuriant specimens. Leaves involute, somewhat pun- 

 gent. Ligule ovate, bluntish. Glumes rather acute, shorter than the 

 lowest continuous flor.et, with 3 ribs. Outer glumella firm, purplish, 

 slightly silky at the base, on the central and two lateral ribs. 



XX Boot fibrous. Rachis ajid branches of the panicle rough to the touch. 



4. P. distans L. {reflexed M.) ; panicle spreading, branches 

 at length deflexed, spikelets linear of about 5 (3-6) obtuse 

 florets which are faintly 5-nerved, the midrib not reachinrr to 

 the points, leaves mostly plane, stem decumbent at the base, 

 root hbrous. E. B. t. 986 : Parn. Gr. tt. 41, 96, 97. Scle-

 tuse. 13ranches of the ;ja?«e/e singularly deflexed, slender; lower ones 

 usually 4—5 together. Spikelets not nearly so long as in the last spe- 

 cies. Glumes much shorter than the contiguous florets, unequal, ob- 

 tuse, obscurely 3 -nerved. Outer glumella silky on the midrib, with 

 two_ lateral nerves at the base. Allied to the last, but distinct in the 

 panicle, smaller spikelets, and fibrous root without rooting scions. Gl 

 intermeaia Khngraaf, supposed to be intermediate, is said to have been 

 round at Lazenby, on the Yorkshire coast ; but we have seen no specimens. 



5. P. Borreri (Borrer's Sea M.) ; panicle spreading, in fruit 

 a cending and patent, spikelets linear of 4-7 florets, outer 

 glumella obsoletely 5-nerved obtuse with a minute point formed 

 by the excurrent midrib, leaves flat, roof tufted. Farn. Gr.
