304 T. Holm — Studies in the Cyjoeracece. 



row (4 mm ), carinate, light green, scabrous ; culm about 75 cm in 

 height, erect, slender, but somewhat stiff, triangular, scabrous, 

 phyllopodic ; spikes 4 to 5, the terminal staminate, long- 

 peduncled, the lateral pistillate, contiguous, seldom remote, 

 short-peduncled, erect, dense-flowered, cylindric, from 2 to 4 cm 

 in length, subtended by sheathless, narrow, foliaceous bracts, 

 the lowest one exceeding the inflorescence; scale of staminate 

 spike oblong, obtuse, light reddish-brown with pale midvein ; 

 scale of pistillate spike lanceolate, acute, blackish with pale, 

 not excurrent midvein, narrower, but about as long as the 

 perigynium ; perigynium sessile, broadly elliptical, granular, 

 compressed, prominently 3-nerved, brownish, prominently 

 denticulate along the margins from near the base to the short, 

 e margin ate beak ; stigmata 2.

Of these G. eurycarpa is a very slender plant and much 

 more so than any of the numerous specimens of C. Neovaskensis, 

 which we have studied. The broad perigynium with the beak 

 merely emarginate constitutes, also, a good distinction. In the 

 other, 0. oxycarpa, we have, also, a plant of slender habit, but 

 the spikes are relatively heavy, and the perigynium is here 

 merely 3-nerved and with the margins quite prominently 

 denticulate from the base to the emarginate beak. 



The affinity of these two species is unquestionably with C. 

 JVehraskensis Dew., next to which they should be placed in 

 the system. 



Carex campylocarpa sp. n. (figs. 13-15). 



Rhizome with short stolons and purplish, persisting leaf- 

 sheaths ; leaves shorter than the culm, narrow, but flat, sca- 

 brous along the margins and on the lower face ; culm about 

 40 cm in height, erect, stiff, triangular, scabrous, phyllopodic ; 

 spikes 3 to 4, mostly 3, the terminal staminate, the lateral pistil- 

 late ; remote, sessile or nearly so, erect, dense-flowered, short 

 cylindric to ovoid, from -J to l cm in length, subtended by sheath- 

 less, foliaceous bracts, shorter than the inflorescence ; scale of 

 staminate spike lanceolate, obtuse, purplish brown with pale 

 midvein ; scale of pistillate spike ovate, obtuse, blackish with 

 the midvein faintly visible and the margins narrow, hyaline, 

 much shorter than the perigynium ; perigynium shortly stipi- 

 tate, spreading, elliptical-oblong, granular and prominently 

 denticulate along the upper margins, turgid, nerveless, pale 

 green with purplish spots and streaks, the beak quite promi- 

 nent, excurved, the orifice entire ; stigmata 2, style not ex- 

 serted.
