in the glumes, fewer-nerved perigynia, smaller ovoid always pointless 

 perigynia. From C. Jlaccosperma it differs in its smaller ovoid always 

 pointless perigynia. C. jlaccosperma and C. grisea agree in their ob- 

 long and pointed or almost rostrate fruit. The closest affinity of C. 

 glaucodea is probably with C. granulans. 



Carex Sartwelliana, Olney, n. sp. : spica subelongata castanea 

 6 spiculis 5-6 (rarius 4- 8) cylindricis densifloris erectis, terminali 

 mascula, reliquis foemineis castaneis sub-squarrosis sessilibus approx- 

 imatis ; bracteis evaginatis, inferioribus culmura superantibus vel infima 

 subinde sterili reraota vaginata ; stigmatibus 3 ; perigyniis castaneis 

 triquetris rostratis (ore integro oblique secto) undique pubescentibus 

 squama ciHata et pubescente lanceolata cuspidata vel ovata castanea 

 nervo viridi latioribus et longioribus ; achenio perigynio conformi tri- 

 quetro angulis costatis. — California, Yosemite Valley, alt. 6,000 feet, 

 Brewer, 1,636 ; Bolander, 6,221. Culms 2-3 feet high, glaucous, and 

 whole plant pubescent, the sheaths of the leaves densely so. Allied to 

 C scahrata, Schw. and G. amplifolia, Boott ; the three species forming 

 a natural group. From the latter it may be distinguished by its shorter 

 fertile spikes and densely tomentose or pubescent perigynia : from the 

 former by the shape of its almost nerveless perigynia. — The C. Sart- 

 wellii of Dewey being only G. disticha, the present well-marked species 

 is now dedicated to the memory of the late Dr. Henry P. Sartwell, 

 of Penn Yan, New York, who has done so very much for the 

 Caricology of the United States. 



Carex cinnamomea, Olney, n. sp. : spicis 3-5 erectis, terminali 

 mascula fusiformi cinnamomea longe pedunculata, reliquis foemineis 

 cylindraceis densifloris, superioribus appi-oximatis, inferioribus longe 

 exserte pedunculatis basi attenuatis laxifloris, infima remota ; bracteis 

 vaginalis culmo longioribus vel brevioribus ; stigmatibus 3 ; perigyniis 

 ellipticis triquetris viridibus rostellatis glabris nervatis (ore bidentato 

 intus ciliato) squama ovata vel obtusa membranacea spice ciliata cinna- 

 momea medio viridi latioribus longioribus ; achenio triquetro obovato. 

 — Swamps of Red Mountain, Humboldt Co., California, Bolander, 

 6477. Culms 12--2 feet long, erect, with short and narrow scabrous 

 leaves, the rudimentary ones dark purple. The species belongs to the 

 Debilis group, agreeing w^ith G. Sidlivantii, Boott, in having erect fir- 

 tile spikes, and with G. glabra, Boott, in its sharply two-toothed, prom- 

 inently nerved, and smooth perigynia.
