472, flowers size of the first, but of an incarnate 
color, instead of blue, the calix is margined of 
same color. Autumnal. 
971. Anthopogon albescens Raf. stem te- 
rete trifid, leaves patent narrow lanceolate acute, 
peduncles terete, calix deeply 4fid, segments 
ovate lanceolate obtusely acuminate, 2 nar- 
rower lanceolate, corolla hardly longer than 
calix unequally denticulate — in Louisiana, col- 
lected by Riddel, sent me anonymous, very dis- 
tinct by smaller shorter flowers nearly white or 
blush color, leaves nearly as in A» virgatum 
but broader and spreading, 2 inches long, flow- 
er only uncial. 
972. Anthopogon brevxfolium Raf. humble, 
uniffore ? foliose anceps, lower leaves cnneate 
or spatulate acute, upper ovatoblong short 
acute, calix with segments shorter ovate lan- 
ceol. acutely acuminate, corolla double of calix 
fringed — in Mts. Alleghanies of Lycoming Cy. 
Pennsylv. blossoming in November, stem 4 to 6 
inches high, leaves very short 4 to 6 lines long 
and reaching to near the flower, which is small 
though elongate uncial, apparently incarnate in 
the specimen, nearer to A . incarnatum than 
to A . crinitum , perhaps a variety of it.— A. 
crinitum differs from all my 4 sp. by leaves 
ovate lanceolate subdeltoid, flowers large with 
rounded segments deeply fringed, peduncles 
naked 4gone Sl c. All belong to the G . An- 
thopogon of Necker 1799, and have the calix 
unequal as in the whole family. 
973. Pleienta quinquenervxa Raf. stem 
terete trichotome, leaves broad oblong lanceo- 
late acute thin 5nerved ; flowers corymbose, 
calix base membranose, 6-7parted, segments fo- 
liose lanceolate, subequal to corolla segments
