elongated, much contracted, and spiciform, Spikelets 8-10-flowered, 3 lines long, and scarcely 
half a line wide. 
Festuca. Kern River. This I have not received before, and it is not described as a North 
American Festuca. It may, however, be a Chilian species, and I regret not having the means 
of determining it at present. It is a tall grass, with flat smooth glaucous leaves, and a long 
contracted panicle. The spikelets are about 10-flowered. Glumes very unequal; the upper one 
much longer, and abruptly mucronate at the tip. Lower palea hairy on the margin toward the 
base, bifid at the tip, with a short straight bristle between the teeth. Upper palea much 
smaller. 
PHRAGMITES COMMUNIS, Linn. Warm Springs, Cohuillas. 
ELYMUS ARENARIUS, Linn. Posa creek; August. This occurs also in other parts of California, 
but is not found on the eastern side of the continent. 
Panicum Crus-GALLI, Linn. Var. Setaria Californica, Kellogg, in Proceed. Calif. Acad. Nat. 
Sc. p. 27? Kern River. This is a very tall form. The panicle consists of numerous approxi- 
mated appressed branches, forming a dense spiciform inflorescence. The flowers are awnless ; 
the inferior glume short and very broad, with a minute abrupt point. Dr. Kellogg’s plant was 
found at the head of the Sacramento Valley. 
PANICUM CAPILLARE, Linn. With the last. It agrees with the Eastern grass, and it may be 
anintroduced species in California,
