the upper sheatli, open, 8 to 12 inches long; rays tenuite ov in pairs, distant, few- 

 llowered ; glumes about an incli long, nearly ecjual, 5-nerved, with a Kjug subulate 

 point : iioret (inchiding calhis of 2 lines) (i lines long, readily deciduous ; lower 

 palet rather sparsely ])ubescent with coarse hairs, but with no distinct corona ; awn 

 4 to 6 inches long, seldom distinctly geniculate, scabrous esi)ecially above, shining, 

 variously curled and twisted, soon deciduous ; upper ]>alet equalling the lower : 

 stamens 3 ; anthers inucioiudate at a{)ex (but not barbulate as described by Trin.

Mono Lake {Bolaudcr) ; Western Nevada ( iratson) ; Oregon (Spauhling) ; and fiom tlie Upper 

 Missouri to II tali, Nebraska and New Mexico. A jiaie green species, which presents very different 

 aspctts according to age ; when young the ]ianicle, all save its long awns, is inclosed by the 

 upper slieath ; later it is e.\serted, witii its f<w rays spreading, but as its liorets are early decidu- 

 ous it at that time rarely hasanytiiiug but empty glumes. It is very near .S'. capillata, Linn., of 

 Europe, from which it diil'ers in its broader leaves, longer and acute ligule, more spaisely iiowered 

 panicle, and longer and more attenuate-])ointed glumes. The plant cited by Mr. liolander as a 

 smooth-awned ,S'. occidentalis is this species with rather shorter awns than usual. 



5. S. setigera, Presl. Culm 1 to 3 feet high, pubescent at the nodes, with radi- 

 cal leaves about one-third as high ; culm leaves Hat, 2 or 3 lines wide below, long- 

 attenuato above, rough-pubescent and sometimes ciliate on the margins, the 

 upi)ermost nearly ecpialling the panicle; ligule about 1 line long, truncate and sjdit ; 

 sheaths two, jiilose at throat, the lower shorter than the interr.oile, the upper loose : 

 panicle about ti (sometimes 12) inches long, mostly included btdow, loose, llexuose, 

 more or less secund when young, the slender rays in pairs ; pedicels shorter than the 

 sj)ikelets : glumes (J to 9 lines long, long-acuminate, the up])er rather shorter, usually 

 purplish, .strongly 3-nerved : Iioret (including a callus of 1 line) 5 lines long, con- 

 .stricted below a distinct corona; lower palet tubercular-roughened, silky hairy 

 especially on the nerves; upper palet hyaline, scarcely a thinl as long; awn 2 to 3 

 inches long, slender, tlexuose, more or less distinctly bent above the middle, strongly 

 pubescent below, minutely so above, i)ersistent : anthers bearded at the apex. —

Common from San Diego County (Parrij), northward to Oivgon (Ifiilsc) ; New Mexico and 

 Texas, and in South America. A rather variable siiecies, often with closely involute leaves. The 

 Uj)per glume has sometimes one or two additional nerves (" r>-nerved," J'iral) ; in the Calitornian 

 specimens the gliunes are generally purple, and in those from Texas they are scarious. The palets 

 ditfer as to their pubescence, which, so tar as noticed, never comiiletcly covers the surface. It is 

 common on the Coast Kanges and on the foot-hills of the Sierra Nevada and, according to I'rof. 

 lirewer, is the most common and valuable " Bunch-Grass" of the dry hills. 



G. S. eminens, Cav. Culms 1 to 3 feet high, slender, pubescent at the nodes : 

 leaves all convolute-setaceous, somewhat rigid, slightly scabrous, those of the radical 

 tufts about half as long as the culm ; lower culm leaves C to 8, the uppermost 2 

 inches long ; ligule very minute ; sheaths striate, smooth : panicle 4 to G inches 

 long, soon exserted, somewhat secund, the very slender rays short, in pairs, few- 

 Howered : lower glume about 5 lines long, the upper 4 lines, acuminate, 3-nerved, 

 l)nrplish : floret a little more than half tlie length of the lower glume ; callus less 

 than i line long ; corona short, but distinct ; lower palet hairy throughout, the upper 

 about one-third as long and hyalint; ; awn about 1 inch long, vi-ry slender, bent near 

 the middle, minuttdy and oveidy scabrous, readily falling away: stamen 1, small, 

 oval. — Icon. v. 42,1 4G7 ; Trin. & Un\)r. Stipaceie, 30. 



Coast Ranges and foot-hills ; also from Quito in South America. Often confused with the pre- 

 ceding by collectors, some slender forms of which closely resemble this. The longer Iioret, with 

 more conspicuous callus and corona, the pubescence not covering the whole palea, and the nuich 

 longer more pubescent ami peisisteut awn of that species as well as the longer gbunes and pilose 

 sheaths will ruadilv disting\iish it.
