apex; achenium ovate, rusty-olive. Culm 2- 3° high, rigidly erect, triquet- 

 rous, rough above and between the spikes ; the sheathing leaves long, fibril- 

 lose.— California, (Hartweg, Coulter, &c.; 529, 672, 682, 683, 1566, 2629 

 and 3866 Brewer, and 27 Bolander.) Banks of the Provo River, in the 

 Wahsatch ; 6,000 feet altitude ; July. (1,245.) 



Caeex Watsoni, Olney. New sp. Culm 18' high, erect, leafy ; leaves 

 clasping at base, the 2 uppermost much exceeding the culm, the lower short 

 and sheathing ; spikes 7, deep reddish-brown (claret,) the upper 4 staminate, 

 the topmost long and the rest short, all aggregated ; barren scales acute, 

 lanceolate, hispid, aristate, membranous, deep-claret on the margins with a 

 pale 3-nerved centre, ciliate at the apex ; stigmas 2, short ; perigynium 

 deeply cleft, the bifid beak spreading and clothed with a few- lax hairs ; scales 

 lanceolate, obtuse, hispid, aristate, the apex cifiate. — Washoe Mountains, on a 

 creek-bank at the mouth of King's Canon near Carson City : 4,500 feet alti- 

 tude ; May. This species has some slight resemblance to C. Schottii, a plant 

 found by Dr. Parry at Santa Barbara, California, and described by Dr. Dewey in 

 Bot. Mex. Bound, without the aid of stigma, style or perigynium and, I believe, 

 without leaves, yet looking so unlike any other American form that there was 

 little doubt that it was new to our Flora. The present plant differs from 

 that in its staminate and pistillate scales — and in what other points "wdio can 

 tell! (1,246.) 



Caeex eigida. Good. Greenland and the Arctic Regions of America ; 

 CaHfomia; Colorado; Northeastern Utah, in the Uintas, .(Hayden, 1870.) 

 Clover Mountains, Nevada ; 10,000 feet altitude ; September. Pursh mentions 

 a doubtful form from hemlock woods of Vermont and New Hampshire. (1,247.) 



Caeex saxatilis, L. (C. pulla, Good.) Spikes 2-3, the staminate 

 single, the pistillate generally remote, the lowest peduncled ; bracts short, 

 erect; stigmas 2; perigynium spreading, elliptic-globose, blackish-purple, pale 

 at base, beaked, emarginate at the orifice, nerveless, longer than the obtuse 

 ovate dark scale, which is membranous at the apex ; achenium obovate, lentic- 

 ular-compressed, of a pale-rusty color. — Greenland ; Arctic America, accord- 

 ing to Boott, but this last is probably C. compacta, a quite distinct species. 

 Var. MAJOE. Spikes 4-5, cylindrical, bright-rusty, the staminate 2, rarely 1, 

 slender, acute, the pistillate 2-3, subremote, thick, obtuse, the lower pedun- 

 cled, sheathless and shghtly nodding ; stigmas 2 ; perigynium oblong-ovate,, 

 beaked, bifurcate, inflated, /ew- and distinctly nerved, suberect, reddish-brown,
