1901] Fernald, — Vascular Plants of Mt. Katahdin. 17I 
C. debilis, Michx., var. Rudgei, Bailey. Lower portions of the 
mountain. 
C. fava, L. Wet shelves at 1230 to 1385 m. (4000 to 4500 ft.). 
West wall, North Basin. 
C. flava, L., var. pumila, Cosson & Germain (C. viridula, Michx.). 
Depot Pond. 
** C, (Oligocarpae) katahdinensis. (Plate 32.) ^ Caespitose + 
leaves flat, 1 to 2.5 dm. long, 3 or 4 mm. broad, more or less sca- 
brous on the margins, with the similar bracts very much (2 to 6 times) 
overtopping the slender rough-angled culms : pistillate spikes mostly 3 
or 4, all approximate, or the lower remote, short pedicelled, 8 to 14 mm. 
long, 5- to 1o-flowered ; scales ovate, scarious, whitish, with green 
midrib prolonged into a slender smooth or rough awn: perigynia 
elliptic, 3 or 4 mm. long, mostly exceeding the scales, obscurely resin- 
ous-punctate or glossy, 16- to 24-nerved, essentially beakless, with 
entire orifice: staminate spike short-peduncled or subsessile, 5 to 8 
mm. long, generally hidden by the upper pistillate ones; flowers very 
few ; the lower scale bract-like and rough-awned, nearly equalling the 
spike, the others acuminate. — Gravelly margin of Depot Pond, 
entrance to the Great Basin of Mt. Katahdin, July 16, 1900 (E. F. 
Williams, J. R. Churchill and M. L. Fernald). 
A species intermediate in some of its characters between C. cono- 
idea and C. oligocarpa. Its perigynium in shape, color and nerving 
is essentially like that of C. conoidea. The staminate spike and the 
elongated bracts are more as in C. o/igocarfa. In its short culms, very 
much exceeded by the leaves, and in its approximate spikes it is un- 
like either of those species. C. oligocarpa is unknown east of the 
Connecticut valley; and although C. conoidea — chiefly a coastal 
species in Maine — follows the Penobscot to Eddington and occurs 
in the St. John valley, itis a plant of low altitudes and may be quickly 
distinguished from C. katahdinensis by its tall culm, scattered spikes, 
short bracts, and the longer elevated staminate spike with mostly 
oblong blunt scales. 
C. laxiflora, Lam., var. varians, Bailey. Woods in the Great 
Basin. 
C. pedunculata, Muhl. Katahdin (Bake). 
C. scirpoidea, Michx. Common. 
C. deflexa, Hornem. Common both in woods at the base and 
among rocks on the summit ridge. 
C. Novae-Angliae, Schw. Common in the Great Basin.
