difficulty, particularly when dried, are readily so from any other 
species of the genus. 
|| Outer glumella with 5 usually faint but distinct nerves, cylindrical 
beloiv, often keeled at the apex , or with a very minute mucro, not 
webbed at the base. Glumes ‘i-nerved, unequal. Glyceria Sin. 
Sclerochloa Beauv. 
| Creeping, or with rooting ascending scions. 
3. P. maritima Huds. ( creeping Sea M.) ; panicle erect sub- 
coarctate (rigid), spikelets linear of 5 — 10 obtuse apiculate 
florets which are faintly 5-nerved, the midrib reaching to the 
point, leaves usually convolute. E. B. t. 1140: Pam. Gr. tt. 
42, 99. Glyceria Sm. Sclerochloa Lindl. 
Sea-coast, frequent. If. 7. — Culms 8 — 15 inches high, rigid, 
glaucous. Lower branches of the panicle usually in pairs, but some- 
times 3 — 5 in luxuriant specimens. Leaves involute, somewhat pun- 
gent. Ligule ovate, bluntish. Glumes rather acute, shorter than the 
lowest contiguous floret, with 3 ribs. Outer glumella firm, purplish, 
slightly silky at the base, on the central and two lateral ribs. 
|| Root tufted. Scions wanting. Rachis and branches of the panicle 
rough. 
4. P. distorts 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 reaching to 
the apex, leaves mostly plane, stem decumbent at the base.

Sandy ground, principally near the sea. Near Dublin. If.. 7, 8. 
— One foot high. Leaves linear, plane, not pungent. Ligule short, 
obtuse. Branches of the panicle deflexed, slender ; lower ones usu- 
ally 4 — 5 together. Spikelets not nearly so long as in the last species. 
Glumes much shorter than the contiguous florets, unequal, obtuse, 
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 tufted root without rooting scions. 
5. P. Borreri Hook. (Borrers Sea M.) ; panicle spreading, 
in fruit ascending 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. Pam. Gr. t. 98.

Brackish places in the south-east of England, not uncommon, often 
growing with P. procumbens and P. distans. If. ?. 7. — “ May be 
distinguished from P. distans by its ascending branches when in fruit, 
the spikelets seldom more than 4- flowered, the exterior glumella 
pointed, and its dorsal nerve extending to the apex ; — from P. pro-
