PANICUM VIRGATUM—Tall Panic grass, Switch grass. 
Description.—A. tall perennial grass, 3 to 5 feet high, growing mostly 
in clumps in wet or moist soil, particularly near the coast. The culms 
are firm, unbranched, except near the top, where they open into an 
ample spreading panicle, sometimes 2 feet long ; the leaves are from 1 to 
2 feet long, flat, rough- -margined, ; 4 to4inch broad. The spikelets are 
large, 4 inch long, ovate and pointed, on smooth flexuous pedicels; the 
glumes are long-pointed, the lower one- half aslong gastheupper. Thelower 
flower has 2 palets and contains 3 stamens ; the upper or perfect flower 
is obtusish and shorter than the upper glume. The branches of the 
panicle are at first erect and appressed, finally spreading; they are in 
whorls around the stem, 5 to 9 branches in the lower whorls, fewer in 
the upper ones. 
Uses.—This is a good and prolifie grass, if cut when young ; when ripe 
it becomes harsh and unpalatable. It forms a considerable constituent 
of the native grasses of the prairies, pata of moist localities.
