136 Rhodora [JuLy 
give the spikes a checkered or mottled appearance. It is as yet known 
only from Washington County, Maine. 
CAREX ARCTA Boott. Alluvial woods along the Nerepis River, 
Westfield, New Brunswick. Not previously recorded from New 
Brunswick, though known from the upper St. John in Maine. 
X CAREX HELVOLA Blytt (C. canescens X norvegica). Plants which 
were apparently a hybrid of Carex canescens and C. norvegica were 
found in a brackish marsh on the east side of Moose Island in Passa- 
maquoddy Bay, and later a similar colony was found in a fresh-water 
swamp at Pembroke, Me. ‘The specimens are mostly infertile and 
compare well with Scandinavian material except that the spikes are 
more remote, a trait traceable to our C. canescens, var. disjuncta 
which is more abundant than the typical form in eastern Maine. 
CAREX MARITIMA O. F. Müller, var. ERECTIUSCULA Fernald, 
Ruopoma ii. 170 (1900), known before only from Cushing, Maine, 
was found in some abundance in a meadow at Pembroke, Maine. 
The Pembroke plant is much larger than the original Cushing material, 
the pistillate spikes being 3.5-7.5 cm. long. 
CAREX AQUATILIS Wahlenb., var. cusprpaTa Laestad. was collected 
in wet meadows four or five miles apart in Pembroke. Though known 
from the lower St. Lawrence in Quebec, from Nova Scotia, and from 
northern New Jersey, this variety has not been reported, apparently, 
from New England. It resembles forms of C. salina, but is strongly 
glaucous. 
CAREX VAGINATA Tausch, formerly known in Maine only from 
the Arbor Vitae swamps of Aroostook County, was found in a small 
open meadow-like spot in a thicket between Julia's Cove and Boot 
Cove, Lubec, Maine. In eastern Quebec and northern Maine it 
ordinarily grows in a carpet of Hypnum, but at the Lubec station its 
roots were in Sphagnum. 
CAREX PENNSYLVANICA Lam., var. LUCORUM (Willd.) Fernald, 
abounds on the sunny slope of an esker near the village of Pembroke, 
Maine, thus extending the known range considerably east of the 
former supposed limits, on Mt. Desert Island and in the Penobscot 
Valley. 
CAREX FLAVA L., var. GASPENSIS Fernald, RHopora viii. 200 (1906) 
was found in profusion along the Meduxnekeag River, in springy places 
in thickets below Houlton. This variety, with slender subulate peri- 
gynia, has previously been known only from river-banks and marl- 
bogs north of the Baie des Chaleurs.
