time he had made another var. £ (Ill. 132, t. 426), founded 
upon plants from the eastern United States. is latter va- 
riety has ever since been regarded as C. aperta Boott, in> 
Gray’s Manual and elsewhere, except in the instance 0 
Olney’s fascicles, whére it was designated as C. aperta var. 
minor Olney. s none of the recent collections from Ore- — 
gon or Washington contain specimens which could be confi- _ 
dently referred to C. aperta, the species has held its place in 
our eastern flora through sufferance. A recent careful exam- 
ination of one of Scouler’s specimens, which is deposited in _ 
herb. Gray, reveals the fact that it is the same as the plant 
now provisionally known in this country as C. acuta var. pro- 
lixa : The specimen: appears to have been one of 
the more slender plants of the original collections, judging 
from the figure in Hook. Fl. Bor.-Am., which figure well 
represents the robust forms of C. acuta var. prolixa. The 
plant of the eastern states can’ not be considered as belong- 
ing to the original C. aperta, and I therefore separate it as

more slender than the species, the basal sheaths not fibril-- 
lose: spikes short (seldom over an inch long), sessile or very 
nearly so, only very rarely attenuated at the base, spreading, 
the terminal staminate flowers few: bracts usually conspicu- 
ously spreading: scales very sharp, spreading, longer than 
the perigynium.—From New England to Illinois and Wis- 
consin; evidently also in Nebraska, Oregon and Washing- — 
ton. Apparently rare. 
6. Carex canescens Linn., emend.—There are three marked © 
types of variation in Carex canescens: (1) A slender and re- 
duced form of the species, very common throughout the 
Northern states; (2) a dwarf series with brown or fulvous 
spikes, subalpine or alpine ; (3) a robust and very leafy form 
gynia long-pointed. Singularly enough, the first form has 
never had a name, although it has passed as var. vitilis and . 
var. alpicola, unless Lastadius’ var. subloliacea may be ap-- 
plied to it. It is very doubtful, however, if this var. sublo- — 
liacea can be legitimately pressed into service for our Amer- — 
hee plant. Andersson’s account of it extends no farther © 
than the fruit and spikes — ‘‘ spiculis parvis, subglobosis,
