A NORTHEASTERN VARIETY OF CAREX DEWEYANA. 
M. L. FERNALD. 
Carex Deweyana Schwein. is one of the most characteristic sedges 
in open woods and thickets from the Straits of Belle Isle to British 
Columbia and south in the Canadian zone, so-called, into the northern 
States. The species is ordinarily an easy one to distinguish at sight 
on account of the long interval which separates the remote long-bracted 
lowest spike from the approximate upper ones. This internode of the 
rhachis between the lowest spike and the lowermost of the upper ones 
varies in length from 1 to 3 cm.; and the remote terminal cluster 
of 2 to 6 spikes usually nods in such a way as to suggest the inflores- 
cence of an overgrown C. trisperma. 
In the Gaspé Peninsula of Quebec, however, Carex Deweyana de- 
parts in its inflorescence from the typical plant above described and, 
as found along the Grand Cascapedia, Grand and Ste. Anne des 
Monts Rivers, has the spikes all approximate or overlapping, the 
lowermost subtended by a short or nearly obsolete bract. In luxuri- 
ant plants the spikes are often 12 mm. long, so that with its over- 
lapping long spikes and often shortened bract the plant very closely 
simulates the closer-headed form of the western C. Bolanderi Olney, a 
species with which the writer was at first inclined to place it. Sub- 
sequent study, however, shows that in its nerveless perigynia and
