Schk, tab. Fff fig. 127. ; 
Spicis distinctis ; spica staminifera solitaria triquetra brac- 
teata pedunculata ; spicis fructiferis subternis tristigmaticis 
alternis subdistantibus oblongis cylindraceis bracteatis cernuis, 
suprema inclusé pedunculata, ceteris exserté pedunculatis, 
et infima sublongo-pedunculata ; fructibus ovatis glabris infla- 
tis subtriquetris rosiratis ore bifido nervosis, squama oblonga 
emarginata scabro-mucronata duplo long‘oribus. 
Culm 15—24 inches high. triangular, scabrous above, 
leafy ; leaves linear-lanceolate, rather rough, about the length 
of the culm, with short sheaths terminating in large, leafy 
bracts which surpass the culm; staminate spike single, rather 
slender, triangular, bracteate ; staminate scale ovate-oblong, 
short-mucronate, tawney, green on the keel; pistillate spikes 
2—4, generally three, rather distant, bracteate, cylindric, ob- 
long, nodding. uprer nearly sessile, Jower rather lonz pedun- 
culate, with quite short sheaths; stigmas three; fruit ovate, 
somewhat triangular, rather long beaked and bifid at the ori- 
ce, glabrous, nerved, nearly horizontal, not so crowded as 
in the preceding species; pistillate scale oblong, distinctly | 
emarginate, terminated by a scabrous point, white. green on 
the keel. Colour of the plant is yellowish green—of the 
spikes, brown near maturity. id

I: some of his letters, Muh. first called this plant C. erina- 
cea, but afterwards adopted the name given it by Willd. The 
description given in Pursh corresponds to the plant, when 
there are only two pistillate spikes, which is not very com- 
mon.in this species. The fig. of Schk. is excellent. 
“This species flowers just after C. tentacu/ata, and is very 
liable to be confound-d with it, especially as it grows in the 
same situations and as its spikes are not at first nodding. Its 
pistillate spikes are commonly longer and smaller in propor- 
tion to thei: length ; and by its recurved peduncles, fruit, and 
pistillate scale, it is readily distinguished from all its related 
species. I have very rarely seen any fruit upon the staminate
