fomia, and Oregon. A common grass in the valleys and on tlie foot-hills 

 through Nevada and in Utah, but eaten by animals only when young; 

 4-6,000 feet altitude ; July-September. (1,333.) 



HoEDEUM PRATENSE, Huds. Culm 1-3° high when growing in water 

 or moist places, with the spike very narrow, 2-3' long ; lateral flowers some- 

 times short-awned, the longer awns sometimes 1' in length. — Ohio to Mis- 

 souri and southward to Louisiana and Northern Texas ; California to Oregon ; 

 Sitka. Diamond and Ruby Valleys, Nevada, and in Salt Lake Valley and 

 the Wahsatch ; 4,300-6,000 feet altitude ; May-July. (1,334.) 



HoEDEUM HiMALAYESSE, Ritt., Var. J^^GicEEAS, Steud. Gram. 352. 

 In a barley field on Antelope Island in Salt Lake. (1,335.) 



Eltmus condensatus, Presl. Bteud. Gram. 351. Culm stout; 3-8° 

 high, roughish-puberulent and short-pubescent at the nodes or nearly glabrous ; 

 spike 3-15' long, erect, exserted or sheathed at base, sometimes close-panic- 

 ulate ; spikelets 2-6 together, 3-10-flowered, puberulent or nearly glabrous, 

 exceeding the internodes of the pubescent rachis ; glumes setaceous-subu- 

 late from a very narrow base, 4-5" long ; flowers 4" long, acute or short- 

 awned, or barely acutish, the upper palet 2-toothed. — Quite variable in the 

 character of the inflorescence, but a now acknowledged distinct species. 

 California to Colorado. Frequent in the valleys and mountains of Nevada ; 

 4-8,000 feet altitude; July-October. (1,336.) 



Elymus Sitanion, Schult. {Sitanion elymoides, Raf. Steud. Gram. 

 351, and Polyantherix Hystrix, Nees. Steud. Gh-am. 356.) Culms 4'-2° 

 high, tufted, and with the leaves and sheaths glabrous or somewhat pubes- 

 cent or scabrous ; spike erect, 1- 3' long, squarrose with its long recurved 

 awns, jointed and fragile at maturity ; spikelets in pairs, 2-5-flowered, 

 smooth or puberulent; glumes entire or usually parted to the base and the 

 segments unequally 2-clefb, the divisions long-awned, (1-3' ;) flowers 3" 

 long, the awn of the lower palet equahng that of the glumes, with often a 

 subsidiary awn or tooth on each side at the apex of the palet.— A very vari- 

 able grass, the true position of which has long been questioned. Later 

 specimens, and especially 637 Vasey, (in part,) in which the glumes are re- 

 duced to the normal pair at the base of each spikelet and the flowers other- 

 wise wholly as in Elymus^ make it certain that Schulte's name should be 

 preferred. From Northern Minnesota to Texas and west to California.
