Carex brachypoda sp. n. (figs. 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 cm in 

 height, erect, stiff, triangular, scabrous, phyllopodic ; 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 cm in length, sub- 

 tended by sheathless bracts with narrow blades much shorter 

 than the inflorescence ; scale of staminate spike lanceolate, red- 

 dish brown with pale mid vein ; scale of pistillate spike ovate, 

 obtuse, black with green, not excurrent midvein, a little shorter 

 than the perigynium ; perigynium minutely stipitate, erect, 

 almost orbicular, granular and denticulate along the margins 

 above, compressed, nerveless, pale green, the minute beak dark 

 purple with the orifice entire, papillose ; stigmata 2. 



Oregon : Crater Lake National Park, Cathedral spring, col- 

 lected by Mr. F. V. Coville, September, 1902 {No. 1455). 



The affinity of this species is with G: gymnoclada, but it 

 differs from this by the perigynium for instance, which is more 

 roundish, denticulate and very shortly beaked. 



Carex pachy stoma sp. n. (figs. 7-8). 



Rhizome csespitose 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 cm in 

 height, erect, somewhat slender, triangular, scabrous, phyllo- 

 podic ; spikes 4 to 6, the terminal and uppermost lateral stami- 

 nate, 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 sheathless, 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 perigy- 

 nium ; perigynium sessile, slightly spreading, elliptical, granu- 

 lar, compressed, nerveless, green or purplish-spotted above, the 

 beak short and thick, sparingly denticulate, the orifice very 

 narrow, slightly emarginate on outer face; stigmata 2.
