it may be expected in the eastern half of the State. 
24. PHALARIS L. (CANARY GRASS.) 
Panicle dense, spike-like, cylindrical, or ovate: spikelets 1-flowered, 
flattened laterally: glumes 5; the outer empty glumes subequal, eari- 
nate, and winged on the keel, exceeding the floret; inner empty glumes 
usually small and inconspicuous, appressed to the lower margins of the 
floret; the fifth or floral glume acute, coriaceous, and shining at matur- 
ity; palet I-nerved, coriaceous, but thinner than the glume: grain 
smooth and shining. 
* Spikelets narrow, acute; inner empty glumes narrow and small, hairy. 
1. P. angusta Nees. Culms rather robust, 6 to 12 dm. high: panicle cylindrical, 
6 to 12 em. long, about 1 em. in diameter: spikelets 3 to 4mm. long; floret three- 
fourths as long as the outer glumes.—Texas to California, in low ground. 
2. P. intermedia Bose, (SOUTHERN €ANARY GRASS.) Culms 5 to 10 dm. high, 
simple: upper sheaths somewhat inflated: panicle 4 to 10 em. long, about 1.5 em.
