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.

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 
an introduced species in California.
