Brackish places in the south-east of England, not uncommon, 

 often growing with P. procumhens and P. distans, %. 7. — *' May 

 b6 distinguished from P. distans by its ascending branches when 

 in fruit, the spikelets seldom more than 4-flowered, the exterior glu. 

 mella pointed, and its dorsal nerve extending to the apex ; — from 

 P. procumhens by its patent branches, its spikelets not more than half 

 the size, and the erect culm ; — from P. maritima by the patent 

 branches, its spikes about half the size, and the flat leaves." Bah, 

 Obviously quite intermediate between P. distans and P. procumhens. 

 GL remota Fries, referred here in last edition, seems to have the outer 

 glumella 7-nerved as in the preceding section, 



6. P. procwahens Curt, (^procumhent Sea 3fJ) ; panicle com- 

 pact ovate-lanceolate disticlio-secund (rigid), spikelets linear- 

 lanceolate of about 4 florets, outer glumella 5 -ribbed obtuse 

 with a minute point formed by the excurrent midrib, leaves 

 flat with inflated sheaths, root fibrous, JE. B. t. 532 : Parn, 

 Gr. t. 42. Sclerochloa Beauv, 



Salt-marshes, in various places, apparently not uncommon in Eng- 

 land. Very rare in Scotland and Ireland. ©. 6, 7. — Culms pro- 

 cumbent, 6 — 8 inches long, glaucous. Leaves linear, obtuse. Ligule 

 short, very blunt. Panicle about 2 inches long, branches patent, dis- 

 tichous, their spikelets secund. Glumes smaller than the florets, ob- 

 tuse, strongly ribbed. Florets oblong, distant upon the rachis, 

 slightly silky at the base. 



*j"["j* Outer glumella with 5 faint hut distinct nerves, membranaceous ^ 



cylindrical below, naked on the nerves and at the base. Glumes 

 1-nerved^ unequal. Catapodium. 



7. P. rigida L. {hard 31.) ; panicle lanceolate (or sometimes 

 a linear simple spike-like raceme) disticho-secund rigid, spike- 

 lets linear acute of 7 — 10 florets, outer glumella faintly 5- 

 nerved obtuse with a mucro, glumes acute unequal, upper one 

 reaching to the base of the third floret, root fibrous. JE. B,

Walls, rocks, and dry barren soils, frequent, 

 plant very rigid and wiry, 3 

 Leaves rigid, linear, setaceous. 



©. 6. — Whole 

 6 inches long^ ascendant or erect. 



Ligule oblong, jagged. Rachis angled, 

 sometimes at once bearing the spikelets (when it much resembles 

 the next species) but more usually throwing out branches, 

 nearly as 



long 



as 



the- contiguous 



florets. 



Glumes 



Florets linear-oblong, 

 rather distant, smooth, bluntish ; outer glumella 5-nerved ; the two 

 lateral nerves broad with a white line down the middle, the two inter- 

 mediate ones very faint. 



8. P. lolidcea Huds. (dwarf Wheat M.) ; spike rigid usually 

 simple unilateral (rarely branched), spikelets linear-oblong of 

 about 8 — 12 florets, outer glumella faintly 5-nerved obtuse
