ington Territory, (Tolmie ;) California, (6472 Bolander;) Colorado, (673 

 Hall & Harbour.) Clover Mountains, Nevada; 11,000 feet altitude; Sep- 

 tember. A dwarf alpine form, 2-5' high, the glumes and palets dark- 

 purple. (1,285.) 



Agrostis elata, Trin. (?) 559^ Torrey, collected near Lake Washoe, 

 Nevada, is very nearly this species, which, however, has been found only 

 eastward, in swamps, from New Jersey to North Carolina. 



PoLYPOGON MoNSPELiENSis, Desf A single specimen of what seems to 

 be this species, 2-3' high, was collected near Unionville in the West Hum- 

 boldt Mountains, Nevada. Frequent in California from Mt. Tejon northward ; 

 perhaps indigenous. (1,286.) 



MuHLENBEEGiA GLOMEEATA, Trin. From the Northern States and Ar-

MUHLENBERGIA SYLVATICA, T. & Gr. Var. (I) SETIGLUMIS. CulmS 1° 



high, nearly erect ; panicle contracted nearly as in M. glomerata, the branches 

 solitary and densely flowered, mostly to the base ; glumes attenuate into a 

 scabrous bristle, 2^-3" long; the palet, with its awn, about twice longer. — 

 Near warm springs in Humboldt Pass, Nevada; 6,000 feet altitude; Sep- 

 tember. (1,288.) The typical form of the species has not hitherto been 

 collected beyond the limits of Gray's Manual, though several Texan and New
