\_P6a. 
cumbens by its patent branches, its spikelets not more than half the 
size, and the erect culm ; — from P. maritima by the patent branches, 
its spikelets about half the size, and the flat leaves Bub. Intermediate 
between P. distorts and P. procumbens, but chiefly allied to the former 
(of which it is perhaps only a variety) by the larger and looser pani- 
cles, and obscure nervation of the outer glumella. 
6. P. procumbens Curt. ( procumbent Sea M.) ; annual, panicle 
compact ovato-lanceolate disticho-secund (rigid), spikelets 
linear-lanceolate of about 4 florets, outer glumella 5-ribbed ob- 
tuse with a minute point formed by the excurrent midrib, leaves 
flat with inflated sheaths. E. B. t. 532: Pam. Gr. t. 42. Gly- 
ceria Sm. Sclerochloa Beauv. 
Salt-marshes, in various places, apparently not uncommon in Eng- 
land. Very rare in Scotland and Ireland. 0. 6, 7. — Root fibrous. 
Culms procumbent, 6 — S inches long, glaucous. Leaves linear, obtuse. 
Ligule short, very blunt. Panicle about 2 inches long ; branches patent, 
distichous, their spikelets secund. Glumes smaller than the florets, 
obtuse, strongly ribbed. Florets oblong, distant upon the partial rachis, 
slightly silky at the base. 
Outer glumella with 5 faint but distinct nerves, membranous, 
cylindrical below, naked on the nerves and at the base. Glumes 
1 -nerved, unequal. Catapodium. 
7. P. rigida L. (hard M .) ; annual, panicle lanceolate (or 
sometimes a linear simple spike-like raceme) disticho-secund ri- 
gid, spikelets linear acute of 7 — 10 florets, outer glumella faintly 
5-nerved obtuse with a inucro, glumes acute unequal, upper 
one reaching to the base of the third floret. E. B. t. 1371: 
Pam. Gr. t. 43. Glyceria Sm. Sclerochloa Panzer. 
Walls, rocks, and dry barren soils, frequent. ©. 6. — Whole 
plant very rigid and wiry, 3 — 6 inches long, ascending or erect. 
Leaves rigid, linear, setaceous. Ligule oblong, incise. Rachis angled, 
sometimes at once bearing the spikelets (when it much resembles the 
next species), but more usually throwing out branches. Glumes nearly 
as long as the contiguous florets. Florets linear-oblong, rather dis- 
tant, smooth, bluntish ; outer glumella 5-nerved; the two lateral nerves 
broad with a white line down the middle, the two intermediate ones 
very faint. 
8. P. lolidcea Huds. ( dwarf Wheat M.) ; annual spike rigid 
usually simple unilateral (rarely branched), spikelets linear- 
oblong of about 8 — 12 florets, outer glumella faintly 5-nerved 
obtuse with a mucro, glumes obtuse nearly equal, upper one 
reaching to the base of the fourth floret. Pam. Gr. t. 43.
