We have accepted Watson’s determination of the North-Mexican specimens indicated. 
above, as Stipa avenacea is an exceedingly common species in the eastern States. He 
also refers Bourgeau’s South-Mexican 669 to this species, while Fournier cites the same 
number under S. eminens ; possibly two species were distributed under this number.

Catirornia.—Souta Mexico, Tacubaya (Schaffner), Zacoalco near Guadalupe (Bour- 
geau, 699). Hb. Kew. 
Fournier also records this species from Quito and Montevideo, but D6ll, (in Mart. Fl. 
Bras. li. 3, p. 8) follows Trinius and Ruprecht in retaining the South-American plant. 
as a distinct species—S. neesiana.
