4. B. secalinus, Linn. Smooth Bye- Brome-grass. Panicle 

 spreading ; peduncles but little branched ; spikelets oblongo- 

 ovate, compressed, of about ten subcylindrical, glabrous, rather 

 remote florets, longer than the awn. Br. Fl. ed. 3. p. 51. E. 

 Fl. v. \.p. 151. E. Bot. t. 1171. 



Corn-fields, &c. ; occasionally. Fl. July, Aug. ©. — Two to three 

 feet high. Leaves somewhat hairy. Calyx and ext. valve of the 

 corolla broadly ovate ; int. valve bifid at the point, the margin 

 strongly ciliated. When the seeds are ripe, the upper spikelets are 

 pendulous, and the florets exhibit more evidently their distaut mode of 

 insertion. 



5. B. mollis, Linn. Soft Brome-grass. Panicle erect, close, 

 compound ; spikelets ovate, subcompressed ; florets imbricated, 

 compressed, pubescent; awn straight, about as long as the 

 glume ; leaves very soft, pubescent. Br. Fl. ed. 3. p. 52. E. 

 Fl. v. i. p. 153. E. Bot. t. 1078. 



Meadows, pastures, road-sides, &c. ; very common. Fl. June. $ . — 

 One to two feet high. Panicle two to three inches long. Spikelets 

 standing nearly erect. Florets five to ten. Ext. valve of the co- 

 rolla convex. 



6. B. racemosus, Linn. Smooth Brome-grass. Panicle erect; 

 peduncles simple ; spikelets ovate, subcompressed, glabrous ; 

 florets imbricated, compressed ; awn straight, about as long as 

 the glume ; leaves slightly hairy. Br. Fl. ed. 3. p. 52. E.

Gravel-pit in the Dublin Society's Garden, and fields in its vicinity ; 

 Mr. Underwood. Near Belfast ; Mr. Templeton. Fl. June, July. 

 ©. ( $ Schrad.) — More slender in habit than the last, and much less 

 downy. The panicle is generally simple, its branches longer and less 

 divided, rough with minute bristles, not downy. Spikelets more turgid, 

 rough to the touch, but naked and shining. I am, however, inclined to 

 think with Dr. Hooker, that it is only a variety of the last. 



7. B. arvensis, Linn. Taper Field Brome-grass. Panicle 

 spreading (at length drooping) ; peduncles branched ; spikelets 

 lanceolate, compressed ; florets imbricated, compressed, gla- 

 brous, about as long as the straight awn ; leaves hairy. Br. 

 Fl. ed. 3. p. 52. E. Fl. v. i. p. 156. E. Bot. t. 1984. 



Moist meadows, near Cullenagh, Queen's County, and fields near 

 Sandymount. Fl. June, July. 0. — About three feet high. Leaves 

 spreading, many-ribbed, hairy, rough edged, either nearly smooth or 

 thickly covered with short deflexed pubescence. Panicle large and 

 conspicuous, with numerous half-whorled, partly compound, harsh, 

 spreading branches. Spikelets drooping and finally pendulous, ovato- 

 lanceolate, variegated with purple and green. 



8. B. erectus, Huds. Upright Brome-grass. Panicle erect; 

 spikelets linear-lanceolate, compressed; florets subcylindrical, 

 remote, glabrous, longer than the straight awn ; root-leaves 

 very narrow, ciliated. Br. Fl. ed. 3. p. 52. E. FL v. i. p. 157.
