MACKENZIE: NoTes ON CAREX 241 
however, long been a favorite theme for discussion among Euro- 
pean students of Carex (Pryor in Jour. Bot. 14: 366; Kiikenthal 
in Allgem. Bot. Zeits. 11: 45), and while the older authors 
generally treat it and Carex Hornschuchiana as the same, later 
authors regard C. /u/va as representiug something else and have 
taken up the name Carex Hlornschuchiana for what was formerly 
called C. fulva. 
While closely resembling this European species, the Boston 
plant differs in the longer perigynia (5-6 mm. long), as compared 
to perigynia of about 3 mm. in length in the European species, 
(Kikenthal, Pflanzenreich 4”: 665, and numerous specimens 
examined by me.) In addition, the usually more obtuse scales are 
very noticeably more white-hyaline at the apex, the spikes are 
wider and heavier, and the sheath is generally more strongly pro- 
longed opposite the blade and more strongly tinged with dark 
chestnut. 
Besides the specimen collected near Boston (possibly introduced 
through wild fowls from further north), I have seen specimens 
from Anticosti (Ellis Bay, John Macoun 50, Sept. 7, 1883) and 
Miquelon (Valley of La Belle-Rivicre, Louzs Arsene 93, July 28, 
1902). It is probable, too, that the reports of the occurrence ot 
Carex fulva in Newfoundland arise from finding this species there.

Culms erect, 3-6 dm. high, growing in medium-sized clumps, 
glabrate or somewhat pubescent, triangular, shorter than or ex- 
ceeding the leaves, somewhat purplish-tinged at base. Well- 
developed blades three or four to a fertile culm, the sheaths short- 
pubescent, the upper not overlapping, blades short-pubescent 
(especially below), 1.5—3 mm. wide, the larger 2.5 dm. long, flat, 
erect-ascending, the uppermost leaf usually inserted shortly below 
and exceeding the spikes; spikes usually two or three, approxi- 
mate, oblong or oblong-cylindric, 5-20 mm. long, 5-8 mm. wide 
(without the scales), the lower half of the uppermost staminate, 
the remainder pistillate, all erect, sessile or nearly so, densely 
many-flowered; bract of lowest spike slender, setaceous, some-
