70 TRIAXDRIA DIGYNIA 



Subdivided, at length Breading, scabrous. Spikelcts about f-flowered, evate-laa 

 reolate, at first erect, finally somewhat nodding, smoothish,or with a very «ho n 

 roughish pubescence under a Ions. Glumes unequal, the lower one shorter and 

 much narrower. Florete closely imbricated. Lower palea lanccoval, ( J nerved. 

 margin membranaceous, two marginal nerves approximated ; awn straight, about 

 as long as the floret, Vjpper palea lance-linear, obtuse, membranaceous, bordororf 

 with a green nerve, ami pectinate-ciliate on the margin. 



Hab. Meadows: W.Chester; near Wynn'e meadows: frequent. 2*7. June. .FY. July. 

 Obs. This specie a has also been introduced. In some respects,— particularly 

 in the size and general character of the panicle,— it approaches B. mollis ; and it 

 may possibly be the plant so named by the American Botanists : But on comparing 

 it with specimens, of both species, which I have received from Europe, lam in- 

 clined to think our plant is the B. arvensis ; and in this opinion ) am fortified by 

 my friend Dr. Pick eki.no. 



3. B. pcbksckns, MuhL Panicle loose, nodding; spikelcts lanceo- 

 late, subterete, 8 to 12-flowcred ; florets pubescent, rather longer than 

 the straight awn. Beck, Bot. p. 408. 

 Pubescent 13 ho mis. 



Root perennial. Culm 3 to 1 feet high, striate, smooth above, somewhat pil ■- 

 below ; node* black. Leaves lanceolate, smooth beneath, pilose above, scabrous 

 on the margin: sheaths nerved, lower once retrorsely pilose, upper one* smooth ; 

 Hgnlc short, laciniate-dentate. Panicle\ >ose, finally nodding ; branches by 2% or 3 

 to f>. slender, subdivided, flexuose, setaceously scabrous. Spikelets oblong-lanceo. 

 late, about 10-llowered. (Humes unequal, ciliate on the keel; the lower one smaller, 

 linear-lanceolate, (almost subulate.) l-m-rved. upper one 3-nerved. Flwets at 



ti^flf jmhr^n^, finally rajb.r niir.n. ItQicer ixtleu lanceolate, 7-nerved, rr wr ad 



with appressed hairs; awn nearly straight, scabrous, rather shorter than the floret. 

 UfayerpaUa linear, membranaceous, bordered with a green nerve, and ciliate on 

 t he margin. 

 JTab. Woodlands, and borders of woods : frequent. Ft. Jane. Fr. July. 



Obs. It is doubtful whether the H. cilia! us, Muhl. grows in Chester C< unty. Thi 

 plant SO called in Florid. Cestr. I believe is not distinct from \). pubescuis,— in 

 which the florets are often conspicuously ciliate. The Brome grasses would pro- 

 bably yield a good fodder; but, with the exception of Cheat— which is much disli- 

 ked on account of its association with wheat' they arc very little known, ui 

 thought of, here. Two or throe other species are enumerated in the V. States.

 [A Latin name for the shoot, or stalk, of a plant ; applied to this genus.] 



Spikelets oblong, more or less terete, at length compressed, acute at 

 each end ; florets sub-terete, mostly deciduous. Glumes unequal, short- 

 er than the lower florets, keeled, acute. Palest lanceolate ; the lower 

 one acuminate, or awned at the extremity, closely embracing the seed. 



I. F. tenella, WUhL Culm filiform ; leaves setaceous ; panicle sim- 

 ple, spikeform, rather secund ; spikelets about 7-flowered ; awns shorter 

 than the subulate florets. Beck, Bot. p. 405. Specim. Gray, Grum.
