CAREX TUCKERMANI NIAGARENSIS; A NEGLECTED 
SEDGE. 
C. P. SMITH. 
Waite in Niagara county, New York, in the summer of 1911, I 
collected a variety of Carex which is not, at least to my satisfaction, 
accounted for in our present-day floras. Every effort to determine the 
form led to C. Tuckermani Dewey; but from that species, as illus- 
trated and described, this plant differs in certain apparent characters. 
Accordingly, after referring to the original description and illustration, 
and examining the material in the C. T'uckermani covers of the Cornell 
University and the U. S. National Herbaria, I have decided to make 
record of the plant as follows: 
CAREX TUCKERMANI niagarensis var. nov. a forma typica differt 
culmis late patentibus; spicis nutantibus, deorsum floribus plus 
minusve laxis; perigyniis latissime ovoideis vel deltoideis, basi pler- 
umque obliquis planisque. 
Differs from the typical form in its widely spreading culms, nodding 
spikes with flowers more or less scattered below, triangular-ovoid, 
deltoid, or even rhomboidal perigynia with the base commonly oblique 
or truncate. 
My No. 2438, 27 August, 1911, Youngstown, N. Y., is taken as the 
type collection. No. 2554 is also typical, being from “West Hill," 
Ithaca, N. Y., 28 June, 1912, matured akenes having been subsequently
