consequence, except requesting you by all means to strike out the 
whole of the description of my proposed new species Carvx 
typhinoides, for I have found it in great plenty this year, growing 
in such a manner as to leave no doubt that it is only a variety of 
C. squarrosa.” 
This statement, however, although enlightening as regards the 
“ Monograph,” is less conclusive than it might appear respecting 
the status of Carex typhinoides. The plant may indeed have been 
a several-spiked form of Carex sguarrosa, long supposed to be a 
monostachyous species, as the “ Table” has it, and known as Carex 
typhina Michx., or it may have been another plant, a species nearly 
allied to Carex squarrosa,which it is the purpose of this paper to de- 
fine. Indeed Dewey interpreted the Schweinitzian plant in terms 
of this very species which he described as Carex sguarrosa vat. 
typhinoides (11: 316,1826). But, while Dewey’s description leaves 
no doubt as to the plant he had in view, it may fairly be doubted 
whether Schweinitz’s name was correctly taken up for it. Should 
such a doubt be insisted on, another name would have to be ad- 
ded to the already overcrowded lists of Carer. It would therefore 
Seem to be a reasonable, if technically vulnerable course to accept 
the interpretation of Dewey, a contemporary of Schweinitz, and 
base on it the identity of the plant which Schweinitz inadequately 
described and subsequently abandoned. 
In now delimiting Carex sguarrosa from Carex typhinoides it be- 
comes necessary to redescribe in detail the former plant in con-_ 
nection with the description of its near ally with which it has 
all along been confounded. 
' CAREX sguARROSA L. 
~ About two feet high, culm slender, smooth below, rough on 
the angles above. Leaves and bracts long and narrowly accumi- 
nate, 2’ wide ( 1/’-3’’), pale green, rough on the edges. Spikes a 
usually 1 or 2, sometimes 3, becoming tawny-stramineous, globose _ 
to oblong-cylindric, rounded at the top, rarely over 1’ long, the : 
terminal one 6-14” long, 8-9” wide, the lower ones much : 
smaller and often sub-globose, on short, slender, ascending pe- 
duncles; staminate portion of terminal spike conspicuous, clavate, . 
rarely less than % the length of the fertile upper portion, some-— 
times 34 its length, the loosely imbricated scales very acute or 
acuminate. Perigynia numerous, much crowded, reflexed at the 
base of the spike, above spreading or slightly ascending, 4 Ff
