(Notes on C'arex, xv.) 

 BY L. H. BAII.KY. 



The following new carices are decribed from collec- 

 tions submitted by the California Academy of Sciences : 



Carex obnupta, n. sp. 



Intermediate between C. laciuiata, Boott, and C. 

 crypt occtrpa, Meyer. Tall and slender, 3-4 feet high, 

 the culm stiff and sharply rough-angled : pistillate spikes 

 about 3. scattered, the lower one or two long-peduncled 

 and drooping, the upper short-peduncled or sessile, all 3 

 to 5 inches long, evenly and narrowly cylindrical, some- 

 what loose at the base, mostly prominently staminate at 

 the apex; staminate spikes 2 or 3, considerably or much 

 elevated: perigynium flat and orbicular-obovate, ridged 

 on the edges, nerveless, usually minutely speckled with 

 colored dots, the beak verv small and short and minutely 

 erose or entire, about the length of and twice or more 

 broader than the thin and black-purple white-nerved sharp 

 or bluntish scale. — San Mateo Co., Kellogg; Sierra Ne- 

 vada (Donnitr), Kellogg d- Bnuinan: Fort Point, San 

 Francisco, Bolander. 



This species lacks the stiff habit of growth of C. laci- 

 niata, as well as the laciniate scale and toothed, tapering 

 perigynium, while the perigynium and short scale are 

 wholly different from those of C. cryptoca?'pa. With 

 the exception of the short scales the spikes of C. obiiupta 

 are verv like those of C . criiiita in appearance. 



Carex quadrifida, n. sp. 



C. atrata, Linn., var. erecta* W. Boott, Bot. Calif., 

 ii, 239, at least mostly. 



* C ert'cta has been before nsed in the oenns. 



2d Ser., Vol. lU. July 3, lt-91.
