The present paper is the result of a study of several collec- 
tions of plants from the southwestern United States and Mexico, 
especially the relatively large series of specimens secured by Mr. 
Harley P. Chandler at Rio Hondo, Texas, and by Mr. Charles 
Russell Orcutt along the Texas-Mexican boundary and in vari- 
ous parts of Mexico. These collections have been received at 
the Missouri Botanical Garden for identification and incidental 
to the work thereto the following plants seem to the writers to 
be worthy of record and characterization.
