THE GENUS CAREX IN CALIFORNIA 



Wet meadows, British Columbia to California, eastward to Montana, In 

 California it is found only in the Coast Ranges from San Francisco northward 

 where it is apparently rare. 



Locs.: San Francisco, Bolander 1568 (in part); Crescent City, Del Norte Co., Dudley. 



Refs.: Carex Cdsickii Mackenzie in Piper & Beattie, Fl. of the Northwest Coast 72 (1915). 

 C. teretiuscula Good. var. ampla Bailey, Mem. Torr. Club 1: 53 (1889), type from Burnt River, 

 east Oregon, Cusick 1331. "C. paniculata L." W. Boott in S. Wats. Bot. Cal. 2: 232 (18S0) in part. 

 "C. diandra Schrank var. ampla Bailey," Kiik., in Engler, Pflzr. 420 : 177 (1909). 



Two separate collections were distributed under Bolander 1508. The present plant was sent 

 to F. Boott and by him named C. paniculata L., which it much resembles. Other specimens dis- 

 tributed under the same number are very mature C. densa Bailey, and in view of F. Boott's 

 determination were a source of much trouble to Olney and W. Boott. 



IX. Stenorhynch.e Holm. Densely cespitose or with more or less elongated 

 rootstocks. Culms triangular or somewhat flattened. Opaque part of leaf- 

 sheaths usually transversely rugulose or red-dotted. Spikes few to many, 

 androgynous or pistillate, but never gynsecandrous, the lower from simple to 

 compound. Bracts little developed. Perigynia plano-convex, yellowish or 

 yellowish-brown, appressed-ascending to spreading, not thick-walled but 

 strongly spongy at base, stipitate, strongly many-nerved, the margins nearly 

 obsolete on the lower half, conspicuously beaked, the beak bidentate. Achenes 

 lenticular. Style jointed with achene, deciduous, its base more or less 

 thickened. Stigmas 2. 



19. C. Jonesii Bailey. (Fig. 11). Cespitose from somewhat elongated woody 

 rootstocks, the culms 2 dm. high, slender, rough above, exceeding the leaves; leaves 

 clustered near base, the blades 1-2 mm. wide; opaque part of sheath white, not 



cross-rugulose, truncate at mouth; spikes 

 in a dense ovoid head, 8-12 mm. long, 8- 

 10 mm. wide, the larger with about 5-10 

 ascending perigynia, the staminate flowers 

 often conspicuous; scales exceeding or 

 shorter than the perigynia, ovate, dark 

 brown with inconspicuous midvein, and 

 hyaline margins; perigynia ovate-lanceolate, 

 3-4 mm. long, 1.5-1.75 mm. wide, rounded, 

 short-stipitate and spongy at base, strongly 

 many-nerved dorsally, and strongly many- 

 nerved ventrally at maturity, slightly mar- 

 gined above, tapering into a very slightly 

 serrulate bidentate beak Y% length of body.
