TRIAND. DIGYN. 35 



I know this plant only from the figure (taken from a cultivated speci- 

 men) and description in E. Bot. To judge from them, I must con- 

 fess, it seems to have few characters to recommend it as a species, 

 though I am not prepared to say to what individual it may belong j 

 probably to P. glauca of the same work, of which Wahlenberg makes 

 it the var. /3. latifolia, panicula magis diffusa: but those very cha- 

 racters may be the effect of cultivation. — See P. nemoialis, var. 

 glauca, of this work. 



11. P. trivialis {roughisfi Meadow-grass), panicle diffuse, spike- 

 lets oblongo-ovate of about 3 flowers which are acute 5 nerved 

 connected with a web, culm and sheaths roughish, iigule ob- 

 long, root fibrous. Light/, p. 97 (P. irivialis and P. an- 

 gustifolia P) . E. B. 1. 10/2. 



Hab. Meadows and pastures, common. Fl. June, July. I/. 



One foot to 2 feet high, ieares linear, acute. Panicle much branched, 



12. v. pratensis {smootli-italked Meadouj-grass), panicle dif- 

 fuse, spikelets oblongo-ovate of about 4 flowers which are acute 

 5-nerved webbed, culm and sheath smooth, liguIe short, root 

 creeping. Liglilf. p. 97. -E. B. t. 1073. 



/3. minor, much smaller., subglaucous, panicle fewer- flowered. 

 P. humilis, E/irh. Gram. p. 115 (fide Sm.). E.B.t. 1004 

 (P. sub ccer idea) . 



Hab. Meadows and pastures, common. — /3. Wall-tops and dry sandy 

 places, not uncommon, Mr. Arnoft. Upland pastures, common, 

 G. Don. Sandy banks Edinb., and sea-.shore Kirkcaldy, Mr. Gre- 

 ville. Duncansby-head, Caithness. Fl. June, July. Jl . 



Much as this species is allied to the last, the differences in the above 

 characters prove the two to be abundantly distinct. \'ar. /3. seems 

 but a starved state of it. 



3. P. annua {annual Meadoiv- grass), panicle siibsecund diva- 

 ricated, spikelets oblongo-ovate of about 5 flowers which are a 

 little remote 5-ribbed destitute of web, culm ascending com- 

 pressed, root fibrous. Lightf. p. 97. 



Hab. Meadows and pastures and by road-sides, every where. Fl. 

 spring and summer. ©. 



Culms 6 — -10 inches long, below prostrate and throwing out roots. 

 Leaves distichous, linear, rather blunt, flaccid, often waved, bright 

 green. Ligule oblong, acute. Panicle pale green, its branches at 

 length much divaricated. CaZ. valves very unequal, ovato-lanceolate, 

 rough at the back, nerved. Ext. valve of cor. ovato-lanceolate, 

 acute, white and diaphanous at the margin, keel and base hairy. 



14. P. nemoralis {ivood Meadow-grass), panicle slender slightly 

 leaning one way lax attenuate, spikelets lanceolate of about 3 

 rather distant slightly-webbed flowers, ligule short truncate, 

 culms subcompressed and sheaths glabrous, root subrepent.
