ALOPECURUS GENICULATUS L. In a roadside ditch, Pembroke, 
Maine. Well known from about Portland, but otherwise unrecorded 
from the State. 
GLYCERIA LAXA Scribn. is abundant in eastern Washington County, 
Maine, and was collected in Westfield, N. B. It was ordinarily easy to 
distinguish it from G. canadensis, but the number of flowers (the key- 
character used in the 7th edition of. Gray's Manual) proved to be 
inconstant. In well-developed G. canadensis the spikelet is broader 
and more turgid than in G. laxa, but the most marked difference 
seems to be in the panicles. In the panicle of G. canadensis there are 
1-3 primary branches at a node, and the panicles are only 2-3 times 
branched; in G. laxa there are ordinarily 3-5 primary branches at 
the middle nodes, and the panicles are 3—4 times branched. 
Bromus ALTISSIMUS Pursh is the common representative of the 
group along the St. John and Aroostook Rivers, and herbarium mate- 
rial shows it to occur in many of the river-valleys of the Gaspé Peninsula 
in Quebec. 
ELEOCHARIS ROSTELLATA Torr. Abundant on salt marshes along 
Winnegance Creek, Phippsburg, Maine. Not previously reported 
from the state. 
SCIRPUS FLUVIATILIS (Torr.) Gray is abundant in the dead water 
at the mouth of the Nerepis River and below it in the St. John in West- 
field, N. B. It had formerly been reported from Perry, Maine, 
though no specimens from that station can now be found. It is 
abundant, however, on tidal flats of Winnegance Creek, Phippsburg, 
Maine, and should be looked for at the estuaries of other tidal streams 
of the Maine Coast. 
CAREX SCOPARIA Schkuhr, var. tessellata n. var., humilis 2-4.5 dm. 
alta; inflorescentiis ovoideis 1.5-2.3 cm. longis; spicis 3-6 confertis 
ellipsoideo-ovoideis 6-10 mm. longis; squamis brunneis; perigyniis 
late ellipticis 2 mm. latis quam squama valde latioribus. 
Low, 2-4.5 dm. high; inflorescence ovoid, 1.5-2.3 em. long; spikes 
3-6, mostly crowded, ellipsoid-ovoid, 6-10 mm. long; scales brown; 
body of the perigvnia broadly elliptical, 2 mm. wide, conspicuously 
broader than the subtending scale.— Marne: damp low ground, 
Marshfield, July 8, 1902 (Fernald); dry low ground, Pembroke, July 
8, 1909 (Fernald & Wiegand, Fernald no. 1464). This is a peculiar 
short-headed plant obviously related to C. scoparia, but with much 
broader perigynia which, being wider than the dark subtending scales,
