Spica staminifera unica; spicis pistilliferis 2-3, subglobosis, 
sessilibus, bracteatis ; fructibus tristigmaticis, ovatis vel subglobo- 
sis, subtriquetris, pedicellatis, hirtulis, nervosis, prolongo-rostratis, 
bidentatis, squama ovata oblonga acuta sublongioribus. 
Culm triquetrous, slender, erect and subscabrous on the angles; 
leaves narrow linear, scabrous on the edge; fertile spikes two or 
three and sessile, ovate and few-flowered ; stigmas three, and very 
long; fruit oviform, tapering below or stipitate, rostrate above, 
- two-toothed ; the beak large and about half the length of the 
whole fruit, and deep-split; pistillate scale ovate, oblong and 
vanica, Lam., and to C. marginata, Schk. It has the same red- 
dish scales, but is easily distinguished by the peculiar shape of 
the fruit and the beak. 
As this species is very distinct, and should be recognized by 
our botanists, I have derived the preceding description from Kunze 
or their benefit. The plant has probably been confounded with 
. emarginata, Schk. Kunze states that it was raised from 
American seed in the Botanic Garden at Berlin, and afterwards 
the plant also was received from a collection made by Rugel at 
Bergen on Broad River, North Carolina, May, 1841. 4 
Though I labelled some specimens, a few years since, by this 
name, I am not confident of their identity with this species of 
Willdenow. The fruit of C. nigromaginata, Schw., is too unlike 
that of this species as given by Kunze. 
Nore.—C. marginata, Muhl. and Schk., has been considered to 
be C. Pennsylvanica, Lam. The former was described in vol. 
xi, p. 163, First Series, and the latter referred to it. A more exten- 
sive comparison of specimens over our wide country from New 
. England to Kansas Ter., has led me to capclude there are tw 
Species under these two names, manifestly distinct. As the one 
as been described, as above, the other is here given.
