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 .............0. eee eee ee eee eee ee eens 2. P. annua. 
1. Psathyrotes scaposa A. Gray, Pl. Wright. 2: 100. pl. 13. 1853. 
Tyre Locauity: “Stony hills above El Paso.’’ 
Rance: 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, Pl. Wright. 2: 100. 1853. 
Bulbostylis annua Nutt. Journ. Acad. Phila, II, 1: 179. 1848. 
Tyre Locaity: “ Rocky Mountains near Santa Fe,’’ New Mexico. Type collected 
by Gambel. 
Ranae: 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.
