long and lax, narrow, linear. Panicle slender, at length some- 
what diffuse. Florets linear-lanceolate, acuminate. Glumes 
narrowed, nearly equal. Palea lanceolate-linear. A plant first 
brought into notice by Walter, who seems to have had rather ex- 
travagant notions of its agricultural value, and afterwards collect- 
ed and cultivated by Fraser, who published a figure of it in the 
Gentleman’s Magazine, October, 1789, together with a specific 
character prepared by Dr. Smith. The name proposed by F'raser 
hould perhaps take the place of Walter’s, whose account is very 
imperfect. 'The principal characters in the above descriptions 
have been noticed, more or less, by the different. authors who 
have published the species, and seem to. be constant in all my 
specimens. —_ ‘

Has. Plymouth, Mass. New Jersey, Dr. Knieskern! Found . 
by me at Plymouth in 1839, and distributed afterwards under a 
provisional name which has not since been taken up by the 
friend who proposed it. C. macrostachys, A. Gr. @ ynehospora 
macrostachya, Torr. in Gray Rhynch. n. 14,) of which the pres- 
ent has been considered a state, hae closely fascicled, and (espe- 
cially the axillary ones) somewhat simple cymes; erectish, stout 
spikelets ; broad-obovate (exactly spoon-shaped with the ; tip 
truncate) nuts which suddenly taper to the produced base, the 
bristles more than twice as long, and the style more than four 
times as long as the nut; and softish leaves which are scabrous 
on the margins and shorter than the culm. In the species now 
proposed all the cymes are compound oe loosely flower- 
ed; the spikelets slender and spreading ; the nuts oblong-obovate 
orrather pyriform, tapering evenly to the acutish base, the bristles 
bout twice as long, and the style more than three times as long ; 
the leaves narrowed, rigid, smooth, overtopping the culm. These 
diag appear to be constant both in the New Jersey and the 
lymouth plants, ——/ ae
