Cinna arundinacea (fig. 72), with somewhat contracted panicle and 
spikelets 5 mm. long, grows in moist, usually shaded places in the 
eastern United States; C. latifolia 
(Trev.) Griseb., with open panicle 
and spikelets 4 mm. long, grows in 
damp woods across the continent in 
the northern part of the United States, 
mostly at medium and high elevations. 
Both species furnish ex- 
cellent forage, but are usu- 
ally not abundant enough 
to be of much importance.
