This species was found by Dr. Gray in meadows at Utica, and 
described in 1834, in the Ann. Lyc. N. York, as a variety of O. 
intumescens , from which species Mr. Carey separated it in 1848, 
in Dr. Gray’s ‘ Manual.’ The large globular female spikes, the 
smooth perigynium with its gradual acumination into a short 
rostrum, its more copious nerves, stouter and smoother culm, and 
broader leaves, sufficiently distinguish it. It has been found by 
Mr. Sullivant in Ohio.

The larger and more numerous spikes, their always alternate 
arrangement, the sessile perigynium and broader aehenium, with 
its more distinctly mammillated angles, are the chief characters 
which distinguish this species from C. lupulma. In ten specimens 
I find five with two male spikes, while in twenty-seven specimens 
of C, lupuiina I find only one with as many. The perigynia in 
both vary in the roughness of the margins of the rostrum. The 
orifice is, I think, generally oblique in C. lupuiina, and the lacinise 
longer, though exceptions may be found to either of these charac¬ 
ters. In both, the lower female spike is sometimes remote, on a 
long exserted peduncle. In one specimen of C. lupuliformis the 
upper female spike is male at base, and the penultimate lower one 
compound at base. I have never seen it beyond the limits of New 
Jersey and New York, while the range of C. lupuiina is from Hud¬ 
son’s Bay to Georgia.
