4, Danthonia, DC.—D, Alleni, n. sp—Culm sparingly branched, 
stout, erect, about three feet high, triangular and compressed (at 
_ least below in the dried state), and with the narrow side concave. | 
Leaves moderately long, flat, about two lines wide ; midnerve con- 
spicuous beneath but not visible on the upper side ; sheaths naked — 
and polished, the lower ones large and conspicuously imbricated 5 
ligule with numerous long and delicate fringes.. (Terminal) panicle — 
decompound, subsecund, rather open, its branches longish and 
(each one) subtended by a subulate bract, which is about as long 
as the glumes. Glumes about reaching to the bristles of the upper-" 
nost flowers of the spikelets. Spikelets about 15 in number, about. 
10-flowered, compact, terete, 6-7 lines long.. Lower (outer) palea . 
clothed with rather numerous long, silky hairs, and with a ¢ stinct ' 
tuft of the same at the base, about half as long as its own awn, dis- 
tinctly about 7-nerved ; awn very slender, setaceous, nearly erect, 
not twisted except at the base, where it is pale in color, very minute- - 
ly and closely scabrous, and somewhat bent sideways ; (Jateral) 
th long-awned. Lateral panicles (only a single one in the speci- : 
men before me) * smaller and partly included. 
This species is readily distinguished from its congeners in this 
country: by its rather tall and stout, somewhat branched culm ; 
‘ed, flat, rather broad leaves of moderate length, with naked and 
Polished sheaths ; larger, open panicle, with the branches 
at the base ; spikelets longer than the glumes; etc. calcd
