INTRODUCTION. 
This second part of the Grasses of the Southwest presents, like the first part, 
plates and descriptions of 50 species of grasses, together making 100. 
The synonymy of such as have had several names is briefly given. Most of 
the species, however, are either new, or so little known that they have received 
but asingle name. The drawings were made by Messrs. Scholl, Olszewski, and 
Holm, and in the details are generally very accurate. I wish to express my obliga- 
tions to Mr. L. H. Dewey, Assistant Botanist, for important assistance in describing 
the species.
