CAREX PYRENAICA AND C. NIGRICANS. 
These species have fewer distinguishing characters than were 
given them by Meyer and Boott. In the Rocky Mountains bs 
species run very close together. Although Dr. Boott regarde 
“perigyniis ventricosis, majoribus, ore conspicue albo-hyalino 
aperto” as good characters to distinguish C. nigricans from ¢. 
Pyrenaica, the forms of the perigynium in our specimens furnish 
no constant differences. They differ as follows: ; 
C. Pyrenaica, Wahl., Act. 139. Two to eight inches high, 
slender; leaves narrow, mostly involute-filiform, shorter than 
the culms; staminate flowers few, occupying a third or less the 
length of the spike ; perigynium few-nerved or nerveless, usually 
shining, little longer than the dark brown or purple scale; spike 
rown or purple, the fertile flowers ercct until full maturity- 
—High mountains of Colorado to California and northward. 
C. sericans, C. A. Meyer, Cyp. Nov. 211. Stouter; leave® 
a line or more broad, nearly flat; staminate flowers usually con- 
spicuous, occupying about half the spike ; perigynium somewh@ 
ventricose, dull; otherwise as in the last, with which it grows 
Evidently the more common species.

SYNONYMY. : 
Carea Parryana, Dewey, includes C. Hallii, Olney, Hay- 
den’s Rep., 1871, 496. In the Preliminary Catalogue of Lieut 
Wheeler's Survey, Mr. Olney noticed the identity of the two Sp& 
cies. 3 
C. Douglasii, Boott, includes ©. Fendleriana, Beklr., Lin 
nea, 39, 185 (878 Fendler). - 
C. rupestris, All., includes var. Drummondiana, Bailey Care® 
Cat., (C. Drummondiana, Dewey). The British American plant 
HABITATS, 
C. Careyana is credited to Oregon in the Carex Catalogue 
on the authority of specimens so named in Hall’s collection. The 
specimens are C. laziflora var. plantaginea. | 
C. acutiformis, Ehrh., (C. paludosa, Gooden.) was credite 
to Colorado by Olney, on a plant of King’s Survey, too. ro 
to be determined. This species is well established at Savin Hill, 
near Boston, where I have this year collected it. ie
