curved at the apex, entire at the orifice; pistillate scale 
ovate, acute, often slightly awned, tawny, green on the keel, 
and a little shorter than the fruit, though variable in its length. 
Colour of the plant rather light glaucous . ; 
lowers in May—grows in woods upon hills ; common, but 
not abundant. 
y Willd. the fruit of this species is called obovate, and it is 
so figured by Schk. I have not seen it obovate, although it 
approaches that form occasionally ; generally it is clearly, as 
described by Muh., ovate, triquetrous. In our woods it often 
attains a greater height than is mentioned: by Muh., and the 
' spikes are rather more remote. Pursh considered this plant 
the same as C. pawpercula, Mx., which is probably not the 
case.

Spikes longer, fruit more remote, peduncles shorter, fruit 
smaller, and its scale about half its length. 
The specimens of this variety, received from Mr. Schwei- 
nitz, are exactly like those found here, which seem to be only 
a shorter and smaller variety of C. oligocarpa.
