Near summit of Carson's Pass {Brewer, n. 2128); on tlie Tiioliminc, at f>,700 feet altitude 

 {Bolandcr, n. 601)8) ; also by Lcmvion, locality not f,'iven. A neat well-maiked species, with a 

 strong general resemblance to C. dcschampsioides, but (tillering widely in tlie structure of the (lower. 



0. sTitic;osA, liong. (Oiay, Proc. Am. A(;a(I. iv. 78), may ]>ossibly occur in nortliern localities. 

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

 jtoint, strigoscly pubescent all over, and especially so on the keid ; tlie lloret considerably shorter ; 

 the awn attached well below the mid<llc, exsertcd and about eciualling the pulet ; hairs copious 

 and one-third shorter Mian tlie acute palct and about etpialled by those of the conspicuous rudi- 

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



* * Panicle narrow, the erect branches oppressed after flowering : loiuer paht 

 sometimes like the (jliimcs in texture. 



0. 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 reacliing the panicle, all convolute, 1 or 2 lines wide, acute, rigid, strongly 

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

 erose-tootheil and cartilaginous ; sheaths loose, the U])per es|)ecially, mostly otpialling 

 the internixles, smooth : i)anicle scabrous, about 2 inches long, very (leiise, occa- 

 sionally interrupted below, the short very rough rays appressed, densely iiowered : 

 s|)ikelets 2 to 2^ lines long on shorter pedicels, brownish-purple above: glumes 

 nearly ecpial, broadly ovate or ovate-lanceolate, rather abru[)tly pointed, the upper 

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

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

 a}iex, scabrous, with hyaline margins, the delicate hairs two-thirds as long ; awn 

 attached just below the middle, rath(>r stout, straight, very slightly exceetling the 

 j)alet, sometimes barely exsertcd ; up|)er j)alet thin, scarcely one-fourth shorter, 

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

 upper palet. 



Swamps, Jlendocino County, Bohimlcr, n. 47*3(5, 4787. Plant with the habit of C. Lapjmiicn, 

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

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

 broader, with fewer ami shorter basal hairs ; the awn is attjiched just below the middle of the 

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

 ous hairs ujion its whole length : in (L Lnpjxmiai they ])roceed from the apex only. The glumes, 

 wherever exposed, are dark brownish-purple; on iIk; back and Ixdow they are very jiale green. 

 The palets arc 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 : patiiclc at first included at 

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

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

 mostly to tlie base : spjkelets rarely exceeding H lines, often blackish purple, some- 

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

 and minutely scabrous all over : floret very slightly shorter ; lower ])alet 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 jjalet ; upper palet hyaline, one third 

 the shorter, 2-nerved antl 2-tootheil : rudiment conspicuous, its hairs about ecpiailing 

 the palet. — Gram. Uni-Sesquill. 22G ; Gray, Proc. Am. Acad. iv. 7S, and Man. GI5. 



Sierm County {Lemm<m) ; Klamath Valley (Cronkhi/r) ; and freipient eastward to the Rocky 

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

 Andersson, in Gram. Scaiid., and (iriseliach, in Ledeb. Flor. Iioss., place C. slricfa, Trin., as a 

 synonym of 0. vnjlcctn, (Jacrtn. What is known to American botanists as C. stricta differs from 

 authentic .specimens of the European C. ve[ilecta in the much lirmer texture of its glumes, the more 

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