1908] Fernald,— Plants of northeastern America 47 
straightish ; the internodes short, 0.5-1.5 (rarely becoming 3) dm. long: 
leaves flat, scarcely crisped at the margin, drying bronze or blackish- 
green, 7-17-nerved, only the midrib prominent; the upper orbicular 
to ovate, obtuse, amplexicaul, 1-3 cm. long; the lower ovate to lanceo- 
late, obtuse or subacute, 2.5—4.5 cm. long: stipules obsolete or when 
present very short and inconspicuous: peduncles slender, not spongy- 
thickened, 2-6 cm. long: spikes 0.7-2 em. long: fruit slender-obovoid, 
2.5-3.2 mm. long, the sides flat and deeply pitted, the back rounded 
and obscurely 3-keeled; style slender and prominent; epicarp olive- 
or reddish-brown, closely investing the seed.— Brackish, occasionally 
fresh, ponds and quiet streams, Newfoundland and Gaspé Co., 
Quebec to Florida, chiefly near the coast, and rarely inland to western 
New York and Michigan. Type collected in pools at Holyrood, 
NEWFOUNDLAND, 23 August, 1894 (Robinson & Schrenk, no. 207). 
The coastal representative of Potamogeton perjoliatus, which has 
ordinarily thicker softer or spongy stems and peduncles; larger crisp- 
margined greener leaves with more numerous nerves (15-27); stipules, 
when developed, nearly 1 cm. long; longer spikes; and larger fruit 
which is more obviously keeled and has a looser-fitting or puckered 
epicarp.

ERIOPHORUM TENELLUM Nutt., var. monticola, п. var., nanum 1—2 
dm. altum; foliis confertis; spicis solitariis; bractea involucris et 
squamis ut apud formam typicam.— Dwarf, 1-2 dm. high, with 
crowded leaves: spike solitary: involucral bract and scales as in the 
typical form.— QUEBEC, in a quagmire at the edge of Lac Chicoutey, 
altitude 975 m., Table-top Mountain, Gaspé Co., August 10, 1906 
(Fernald & Collins, no. 174). A very pretty alpine extreme of the 
common E. tenellum (E. paucinervium A. A. Eaton), in its solitary 
spike suggesting E. C hamissonis, var. albidum; but with the definite 
1-leaved involucre, the elongate acute leaf-blades, and the pale stram- 
ineous scales of E. tenellum. 
CAREX SCIRPOIDES Schkuhr, var. capillacea (Bailey), n. comb. 
C. interior Bailey, var. capillacea Bailey, Bull. Torr. Bot. Cl. xx. 
426 (1893).— In the Proceedings of the American Academy, xxxvii. 
457, 485 (1902) and in other publications the writer has inclined to the 
opinion that Schkuhr's C. scirpoides (1806) could not be maintained
