The analysis of 88 specimens is as follows 
1 had 2 spikes. 75 with the terminal spike male. 
16 „ 3 13 with the terminal spike male at base. 
53 „ 4 
15 „ 5 
3 „ 6 
In 20 the lower or two lowest spikes were compound, and in 15 
the lowest was radical. In one only were there any traces of male 
florets on the upper female spikes. 
This very distinct species, originally found by Nuttall at Lake 
Michigan, extends from the western parts of the State of New 
York to the 60° of latitude in Arctic America, and to the Rocky 
Mountains and the Oregon. 
Carey, I think correctly, allies it to the Banicece, with which its 
globose, turgid, strongly nerved, and at times evidently subex- 
curved perigynium unites it. Gay (An. Sc. Nat. 2 ser. xi. 191) 
includes it in his list of the Acuta, and Tuckerman, in his group 
Bicolores, between Limosce and Atratce. Nuttall places it among 
the species with three stigmata, and describes it as having three; 
but though I observe that number, it is the exception. 
The specimens from Hudson’s Bay are from one to two and a 
half inches high, with three to five spikes; but Sir John Richard¬ 
son’s, from Carlton House, are nearly as tall as the specimens 
from the States.

In 30 specimens I find— 
2 with 2 spikes. 12 with 1 male. 
14 „ 5 2 „ 2 males. 
13 „ 6 16 „ terminal spike male at base. 
1 „ 7 
8 with upper female, male at base. 
7 „ 2 upper females, male at base. 
1 „ 3 upper females, male at base. 
The other specimens are too young to show the distribution of the 
stamens. 
We have no description of this species except by Michaux and 
Kunth. Its discovery in the State of New York was subsequent 
to the publication of the first edition of Gray’s Flora. Pursh con¬ 
founded it with C. granulcvris, and Dewey with C. irrigua, next to 
which {C. paupercula, M.) Michaux had placed it. He takes no 
notice of the number of stamens, but describes the perigynium as 
lenticular, and the terminal spike as male. Kunth, who had au¬ 
thentic specimens, describes it as “inferne mascula.” Michaux 
says, “ capsulis muticis,” but Kunth, more correctly, “ brevissime 
rostellatis.” In the brief mention of it by Gay in the An. Sc. 
Nat., he notices the variation in the terminal spike, but alludes to 
the perigynium as nerveless. Kunth more correctly says, “ utri- 
culis nervosis .” It is an alpine species, growing in moist places. 
Michaux says he found it “prsesertim ad Lacum Cycnorum;” 
Boring met with it at Lake Superior; Tuckerman at Willey''s 
Pond, and Oakes at the South Notch Pond on the White Moun¬ 
tains; Torrey and Gray at Lake Avalanche, New York.
