Hot Springs National Park is particularly rich in the great variety of grasses to be found on its wooded slopes and in its moist valleys and occasional open fields.

The following 64 grasses have been collected in the park and the immediate vicinity. A few are evident escapes from cultivation, but it is interesting to note their persistence and spread in competition with native grasses.

Determinations have been verified by Dr. Jason R. Swallen of the United States Department of Agriculture. Two species, Panicum bicknellii and Paspalum laeve, are reported as being the first specimens received from Arkansas.
