_ Spicis distinctis; spica staminifera solitaria erecta; spicis 
fructiferis tristigmaticis subiernis sessilibus vel incluse pedup- 
culatis distantibus per-paucifloris; fructibus subulatis vel 
subinflato-lanceolatis longis rostratis divaricato-reflexis ore 
integro glabris, squama lanceolata plus quam triplo longiori- 
bus. 
As Wahlenberg had published a species under the name of 
C. subulata, found in the Isle of Bourbon, and very different 
from that described by Michaux, it is necessary to give Mi- 
chaux’s plant a new name. I have chosen for it the name of 
that eminent botanist. 
Culm a foot high or more, triquetrous, slender, smooth, 
lax; leaves fiat, linear, striate, smooth, shorter than the 
culm with striate sheaths; bracts leafy, linear, flat, upper 
ones long as the culm; staminate spike single, short, small, 
with an oblong mucronate white scale ; stigmas three ; pis- 
lillate spikes about three, sessile or with inclosed peduncles, 
two to four flowered, quite distant ; fruit subulate, or long 
lanceolate, rostrate, slightly inflated, entire at the orifice, re- 
flexed and diverging, somewhat two-ranked; pistillate scale 
lanceolate, whitish, nearly one third as long as the fruit. 
Colour of the plant light green. 
Flowers in May and June. Found in Canada, Mx.---Al- 
leghany mountains, Schw.—Also in N. Jersey, whence I re- 
ceived the plant through the politeness of Dr. Torrey. 
This plantis related to'C. leucoglochin, Erh., but is a very 
distinct and finely characterized species.
