ENGLISH BOTANY. 
broad. Panicle 3 to 9 inches long. Spikelets i inch long. Florets 
^ inch long. 
Very similar to P. pratensis, but usually taller and with a larger 
panicle, which does not droop at the apex. The leaves taper more 
gradually towards the apex and are less hooded; the panicle-branches 
are more numerous at the lower nodes of the rachis ; the spikelets 
are smaller and fewer flowered; and the lower pale more regularly 
curved on the back, not distinctly acuminate, and glabrous on the 
margins. 
Var. a is very readily to be distinguished from P. pratensis by its 
rough sheaths, but the most important characters which separate 
P. trivialis from P. pratensis are, the absence of a creeping root and 
subterranean stolons in the former and its long acute hgule.

GENUS XXXV.— BUIZK, Linn. 
Spikelets stolkcd, arranged in a very loose ()])eu panicle, laterally 
compressed, open during fiowerhig, e.-ich containing to 10 perfect 
florets. Glumes 2, nearly equal, suhrotund, c<Micavo, botli shorter 
than the spikelets, not keeled, not awned, 7- to D-ribbed, scarious. 
Pales 2, the lower one concave, rounded on the back, not keeled, 
cordate at the base, entire and obtuse, not awned, faintly 7- to 9- 
ribbed, scarious; upper i)ale suborbicular, truncate, L>-ke(;led." Lodicules 
2, entire or sub-bilobed. Stamens 3. Styles 2, short, pcrsit^tent ; 
stigmas plumose, protruded at the sides of the florets between the 
basal margin of the pales. Caryops adherent to the upper pale, 
glabrous, roundish -ovate, convex on the outside, concave within. 
The Mjune of this genus is derived from the Greek word /J^fyw, I balance, owing
