key to the species. 



Plants scapose, erect; corollas nearly glabrous; leaves almost entire. . . 1. P. scaposa. 

 Plants much branched, spreading, leafy; corollas woolly at the top; 



leaves coarsely toothed 2. P. annua. 



1. Psathyrotes scaposa A. Gray, PL Wright. 2: 100. pi. 13. 1853. 

 Type locality: "Stony hills above EI Paso." 



Range : Western Texas and southern New Mexico. 



We have seen no specimens of this from New Mexico, but the type came from 

 very close to the southern border and perhaps from within our limits. 



2. Psathyrotes annua (Nutt.) A. Gray, PI. Wright. 2: 100. 1853. ^ 

 Bulbostylis annua Nutt. Joum. Acad. Phila. II. 1: 179. 1848. 



Type locality: "Rocky Mountains near Santa Fe," New Mexico. Type collected 

 by Gambel. 



Range : Plains, California and Nevada to Utah and New Mexico. 



We have seen no specimens of this from within our borders. There may have been 

 some mistake made in the citation of the source of the original specimens, but it is 

 not improbable that the plant occurs in the northwest corner of New Mexico.
