    Till AND. DIGYN. 36 1 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 5 probably to P. glauca of the same work, of which Wahlenberg makes it the var. j3. lutifolia, pauicula magis diffusa : but those very cha- racters may be the effect of cultivation.—See P. nemoralis, var. glauca, of this work. 11. P. triuialis {roughish Meadow-grass), panicle diffuse, spike- lets oblongo-ovate of about 3 flowers whicb are acute 5 nerved connected with a web, culm and sheaths roughisli, ligule ob- long, root fibrous.

P. pratensis [smooth-stalked Meadoiv-grass), panicle dif- fuse, spikelets oblongo-ovate of about 4 flowers which are acute 5-nerved webbed, culm and sheath smooth, ligule short, root creeping. Light/, p. 97. E. 3. t. 1073. /3. minor, much smaller, subglaucous, panicle fewer-flowered. P. humilis, Ehrh. Gram. p. 115 (fide Sot.). E. B. 1.1004 (P. subcceruled). Hab. Meadows and pastures, common.—/3. Wall-tops and dry sandy places, not uncommon, Mr, Arnott. Upland pastures, common, G. Don. Sandy banks Edinb,, and sea-shore Kirkcaldy, Mr. Gre- v'dle. Duncansby-head, Caithness. FL June, July. 1/. Much as this species is allied to the last, the differences in the above characters prove the two to be abundantly distinct. Var. /3. seems but a starved state of it. 3. P. annua [annual Meadow-grass), panicle subsecund diva- ricated, spikelets oblongo-ovate of about 5 flowers which are a little remote 5-ribbed destitute of web, cuhn ascending com- pressed, root fibrous. Lighlf. 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. Cat. valves very unequal, ovaio-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 {wood Meadow-grass), panicle slender slightly leaning one way lax attenuate, spikeLets lanceolate of about 3 rather distant slightly-webbed flowers, ligule short truncate, culms subcompresscd and sheaths glabrous, root subrepent.
