nata vel emarginata ferruginea medio viridi nervata plus

Culmus, folia, bractece ut in C. crinita, nisi ligula infima 
elongata, folio impressa, vaginseque foliorum asperatse ! Pe- 
dunculi plerumque longiores, interdum glabri. Spicce rnasculce 
l|-2 poll, longse, 1-1| lin. latse, vel androgynse breviores. 
Spicce fceminece ssepius 3, l|-3^ poll, longse, 4 lin. (vel ex api- 
cibus aristarum basi 5-7 lin.) latse, plerumqne basi magis co- 
mosse. Squamce masculse lanceolatse, acuta;, plus minus cus¬ 
pidatse, ssepe muticse; vel latiores, obtusse: foeminese lanceo- 
latse, adscendentes : inferiores longius aristatse, magis apertse : 
superiores ssepe breve cuspidatse, perigynio breviores vel subse- 
quantes. Perigynium 2-2Ao lin. longum, -^-1 lin. latum, 
ovatum vel ellipticum, laxiuscule imbricatum, oblique adscen- 
dens, magis grosse granulatum, demum interdum ferrugineo- 
punctatum, ssepe tenuiter nervatum. Achenium T V-1 lin. 
longum, yu- lin. latum, obovatum, basi styli apiculatum, ssepe, 
sed rarius quam in C. crinita, pravum. 
A C. crinita, Lam., differt vaginis foliorum scabris !; spicis 
foemineis latioribus, magis laxis; perigyniis ovatis vel ellipti- 
cis, majoribus; squamis foemineis plerumque longioribus, mi¬ 
nus patentibus, superioribus breve cuspidatis, masculis ssepe 
muticis. 
I had separated this plant from C. crinita some years ago, and 
had alluded to it under the name of C. asperata; but on reference 
to the monograph of Schw. and Tor., I cannot doubt that it is 
their C. crinita, [3 gynandra , and therefore the C. gynandra of 
Schw. An. tab., as stated subsequently by Torrey in his Mon. p. 
401. It is remarkable that no one has noticed the scabrous va- 
ginse of the leaves, a character which of itself may serve to distin¬ 
guish it from G. crinita, as C. Hitchcockiana is distinguished from 
G. oligocarpa. I have no other authority for its range than the 
specimens in my herbarium. It is probably more limited than G. 
crinita.
