tember. A dwarf alpine form, 2-5' high, the glumes and palets dark- 
purple. (1,285.) 
Ageostis elata, Trin. (?) 559=* Torrey, collected near Lake AVashoe, 
Nevada, is very nearly this species, which, however, has been found only 
eastward, in swamps, from New Jersey to North Carohna. 
PoLYPOGON MoNSPELiENSis, Dcsf. 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 Cahfornia from Mt. Tejon northward ; 
perhaps indigenous. (1,286.)

MUHLENBEEGIA SYLVATICA, T. & Gr. Var. (!) 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, 2J-3" long ; the palet, with its awn, about twice longer. — 
Near warm springs in Humboldt Pass, Nevada; 6,000 feet altitude; Sep-
