Carices novae Americae Boreali-occidentalis. 51 
: The graceful habit of this species reminds us more of C. rhomboidea 
than of C. vulgaris, but when we, nevertheless, prefer to place it nearer 
C. vulgaris it is on account of the structure of the perigynium, narrowly 
elliptieal and prominently many-nerved. 
2. Carex brachypoda Holm, l. c., p. 302, fig. 4—6. 
Rhizome short with ascending shoots and persisting, dark brown 
leaf-sheaths; leaves shorter than the culm, relatively broad (about 5 mm) 
and flat, deep green, scabrous along the margins and lower face, glabrous 
above; culm about 35 em in height, erect, stiff, triangular, scabrous, 
phyllopodie; spikes 3 to 4, mostly 4, the terminal staminate, the lateral 
pistillate, somewhat remote, sessile or the lowest one short-peduncled, 
erect, dense-flowered, cylindrical, from 1 to 2 em in length, subtended 
by sheathless bracts with narrow blades much shorter than the in- 
florescence; scale of staminate spike lanceolate, reddish brown with pale 
midvein; scale of pistillate spike ovate, obtuse, black with green, not ex- 
current midvein, a little shorter than the perigynium; perigynium minutely 
stipitate, erect, almost orbicular, granular and denticulate along the mar- 
gins above, compressed, nerveless, pale green, the minute beak dark 
purple with the orifice entire, papillose; stigmata 2. 
Oregon: Crater Lake National Park, Cathedral spring, colleeted by 
Mr. F. V. Coville, September, 1902 (no. 1155). 
The affinity of this species is with C. gymnoclada, but it differs from 
this by the perigynium for instance, which is more roundish, dentieulate 
and very shortly beaked. 
3. Carex pachystoma Holm, |. e., p. 302, fig. 7—8. 
Rhizome caespitose with strong roots and persisting, reddish leaf- 
sheaths; leaves almost as long as the culm, quite broad and flat (0,5 cm), 
glabrous, light green; culm from 30 to 56 em in height, erect, somewhat 
slender, triangular, scabrous, phyllopodic; spikes 4 to 6, the terminal and 
uppermost lateral staminate, the others pistillate, remote or the uppermost 
contiguous, all, especially the lower ones, slenderly peduncled, erect or 
spreading, dense-flowered except at the base, from 3 to 5 cm in length, 
subtended by sheathlest, leafy bracts about as long as the inflorescence 
or a little longer; scale of staminate spike lanceolate, obtuse, purplish 
brown with green midvein; scale of pistillate spike lanceolate, mucronate, 
deep purple with broad, green midvein, narrower, but longer than the 
perigynium; perigynium sessile, slightly spreading, elliptical. granular; 
compressed, nerveless, green or purplish-spotted above, the beak short 
and thick, sparingly denticulate, the orifice very narrow, slightly emargi- 
nate on outer face; stigmata 2. 
Oregon: Crater Lake National Park, Anna Creek Caynon, near the 
falls (no. 1362) and near Odell Lake, Klamath County (no. 520), collected 
by Messrs. Applegate and Coville. 
Washington: Springy places, northern slope of Mt. Adams, and 
Falcon Valley, W. Klickitat County (no. 2959), by Mr. W. Suksdorf. 
The species may be placed between C, variabilis and C. lenticularis.
