Thus far I have collected sixteen species of Carex in Ne- 

 vada, all of which have been determined by Mr. Mackenzie, the 

 other eleven not mentioned in this paper having been reported 

 upon by him in volume 5 of this journal, pages 53-58. 



In addition to the above, two other species, labeled C. aquat- 

 ihs and C. usta are in our herbarium, collected in the vicinity 

 of Reno, but I have not had the determinations verified. 



In the Botany of the King Report Olney lists twelve ad- 

 ditional species and several varieties, bringing the total number 

 of species reported from Nevada up to thirty. The species men- 

 tioned by him are: C. aemathorhyncha, aristata, frigida, lepo- 

 nna, Liddoni, mnricata, rigida, Rossii, Sartivellii, scirpoidea, 

 utriculata and Watsoni. The latter is described as new, the 

 type collected at the month of King's canyon, near Carson. A 

 re-examination of the specimens representing the above twelve 

 names would no doubt result in several changes.

 tire, or pinnatifid, dentate above the middle; hispid and scab- 

 rous throughout, with minute barbate hairs; the white hairs 

 springing from an indurated corneous base, or submuricate hir- 

 sute, the hairs with hooked prickles, in whorls, or sometimes 

 scattered, of diamond-like brilliancy; upper leaves subcordate, 

 coarsely dentate at the expanded base; apex (terminal lobe) 

 long, attenuated and entire (about twice the length of the ex- 

 panded sub-clasping lower lamina); scabrous margins, and mid-
