214. Paspalum L.—A large genus of 
probably 200 species, well represented in 
the Gulf and south Atlantic states. It can 
be easily distinguished by the plano-convex 
spikelets in spike-like racemes. There are 
comparatively few species of economic 
importance. They are almost entirely 
absent from the grazing regions of the 
central and western United States, and in 
the southeastern states do not form an 
important constituent of grazing areas, 
being mostly inhabitants of wet or sandy 
soil and not often gregarious. An attempt 
was made, but with little success, to intro- 
duce into cultivation P. dilatatum Poir. 
(Fig. 19), under the name of water-grass. In 
the savannas of Central America certain species, such as 
P. notatum Fligge and P. minus Vasey, are important.
