redivided, the ultimate divisions filiform and considerably ex- 
serted, frequently recurved; sheaths much shorter than the 
internodes, usually about one-half as long, keeled, at least 
above the middle; ligule scarious, abouto.5 mm. long; blades 
erect, flat, folded when dry, minutely pubescent on the upper 
pala linear, 1-2 dm. long, about 2 mm. wide; inflor- 
scence narrow, 4-6 dm. long, its primary branches erect, 
an ultimate divisions sometimes spreading, the sheaths from 
which arise the ultimate divisions narrow and tightly embrac- 
ing them, the spathes 2-3 cm. long, acuminate; racemes in 
pairs, 1.5—-2 cm. long, exceeded by the spathes; sessile spike- 
lets 3-3.5 mm. long, about twice as long as the internodes, 
the awn straight, 11-13 mm. long; pedicellate spikelet want- 
ing, or present as a minute rudimentary scale, the pedicel as 
long as or a little exceeding the sessile spikelet. 
In dry soil, North Carolinato Florida. Type collected by 
Mr. A. H. Curtiss in Florida. This seems to be abundantly 
distinct from A. Vzrginicus, to which it is related, in the 
glaucous hue of the whole plant, the glabrous sheaths and 
especially in the sheaths of the inflorescence, from which 
arise the peduncles bearing the spathes, which are very nar- 
row and tightly enclose the peduncles, making the contrast 
between the spathes and the sheaths very marked.

A glabrous, usually glaucous, tufted perennial. Culms 
5-10 dm. tall, branched above the middle; leaves below the 
inflorescence 3 or 4; sheaths shorter than the internodes, the 
basal ones equitant; ligule scarious, about 0.8 mm. broad; 
blades linear, flat, folded when dry, minutely pubescent above, 
and usually with some long hairs on the upper surface near 
the base, the lower culm-blades 1-1.5 dm. long, 2-4 mm 
wide, the basal blades often much longer: racemes in pairs, 
exserted, rather stout, 4-7 cm. long, silvery white; sessile 
spikelets about twice as long as the internodes, about 5 mm. 
long, the first scale thick and firm, folded near the margins, 
strongly nerved at the folds, the nerves very hispid above the 
middle, the flat glabrous internerve marked with 2-5, rarely 
more, faint nerves, the second scale boat-shaped, thinner, 1- 
nerved, the nerve hispid above the middle, the fourth scale
