line, little divergent ; upper palet usually nearly equalling the lower, very thin, 

 2-nerved and mostly 2-toothed : anthers very large, dark purple or purplish : rudi- 

 ment lar"-e and conspicuous, its abundant hairs nearly equalling the lloret. — 

 Bolanderr Trans. Calif. Agric. Soc. 1864 -G5, 13G. 



Near summit of Carson's Pass {Brewer, n. 2128); on the Tuolumne, at 9,700 feet altitude 

 (Bolandcr, n. 6098) ; also by Lcmmon, locality not given. A neat well-marked species, with a 

 stronff o-en'eral resemblance to C. dcschamjyswidcs, but diH'eiing widely in the structure of the flower. 



C. STKIGOSA, Bong. (Gray, Proc. Am. Acad. iv. 78), may possibly occur in northern localities. 

 It will be recognized by its very large glumes, 2i to 3 lines long, terminating in a long subulate 

 point, strio-osefy pubescent all over, and especially .so on the keel ; the lloret considerably shorter ; 

 the awn attachetl well below the middle, exserted and about e(iualling the palet ; hairs copious 

 and one-third shorter than the acute palet and about equalled by those of the conspicuous rudi- 

 ment. What appears to be Bongard's plant was collected in Alaska by Mr. Harrington. 



* % Panicle narroio, the erect branches oppressed after flowering : lower 2yalet 

 sometimes like the glumes in texture. 



G. C. crassiglumis. Culm about a foot high, erect, rigid : radical leaves 

 nearly as tall, culm leaves 3 or 4 inches long, divergent, the upper smaller, erect, 

 usually reaching the panicle, all convolute, 1 or 2 lines wide, acute, rigid, strongly 

 striate, rough above and on the margins, very pale green ; ligule less than a line long, 

 erose-toothed and cartilaginous ; sheaths loose, the upper especially, mostly ecjualling 

 the internodes, smooth : panicle scabrous, about 2 inches long, very dense, occa- 

 sionally interrupted below, the short very rough rays appre.ssed, densely flowered : 

 spikelets 2 to 21 lines long on shorter pedicels, brownish-purple above : glumes 

 nearly equal, broadly ovate or ovate-lanceolate, rather abruptly pointed, the upper 

 often mucronate, minutely scabrous, subcartilaginous, with thin margins: lower 

 palet scarcely shorter, very broad, acute, lacerate-fringed and obscurely toothed at 

 apex, scabrous, with hyaline margins, the delicate hairs two-thirds as long ; awn 

 attached just below the middle, rather stout, straight, very slightly exceeding the 

 palet, sometimes barely exserted; upper palet thin, scarcely one-fourth sliorter, 

 2-nerved, erose-toothed : rudiment very small, its abundant hairs about equal to the 

 upper palet. 



Swamps, Mendocino County, Bolander, n. 4766, 4787. Plant with the habit of C. Lappmiim, 

 Trin., under which name it was distributed, but very unlike in its flowers. The glumes in this 

 are much broader and less acute, and are remarkably thick and tough. The lower palet is much 

 broader, with fewer and shorter basal hairs; the awn is attached just below the middle of the 

 palet, while in the other it is just above the base ; the rudiment is much larger, with more copi- 

 ous hairs upon its whole length : in C. Lnpponica they proceed from the apex only. The glumes, 

 wherever exposed, are dark brownish-purple ; on the back and below they are very pale green. 

 The palets are more or less purple-tinged along the nerves. 



7. C. StriCta, Trin. Culm erect, rather rigid, 1 to 3 feet high, somewhat 

 scabrous below the panicle : leaves narrow and mostly setaceously involute, erect, 

 scabrous on both sides ; ligule short : sheaths smooth : panicle at first included at 

 base, at length exserted, 2 to 5 inches long, erect, narrow, somewhat lobed, inter- 

 rupted below, the roughened and erect branches much crowded, flower-bearing 

 mostly to the base : spikelets rarely exceeding 1| lines, often blackish purple, some- 

 times straw-colored : glumes ovate-oblong, acute, nearly equal, rough upon the keel 

 and minutely scabrous all over : floret very slightly shorter ; lower palet roughish, 

 bearing the straight awn at or a little below the middle and slightly exceeding it ; 

 hairs at base about two-thirds the length of the palet ; upper palet hyaline, one third 

 the shorter, 2-nerved and 2-toothed : rudiment conspicuous, its hairs about equalling 

 the palet. — Gram. Uni-Sesquifl. 226 ; Gray, Proc. Am. Acad. iv. 78, and i\Ian. 615. 



Sierra County {Lcmmon) ; Klamath Valley (Cronkhifc) ; and frequent eastward to the Rocky 

 Mountains and along the northern border through Wisconsin, etc., to Vermont and Canada. 

 Andersson, in Gram. Scand., and Grisebach, in Ledeb. Flor. Ross., place C. stricta, Trin., as a 

 synonym of C. nccjhxt.a, Gaertn. What is known to American botanists as C. stricta differs from 

 authentic specimens of the European C. nexjJccta in the much firmer texture of its glumes, the more 

 copious and longer hairs at base of floret, the somewhat stouter awn, and longer rudiment.
