Texas, is to be added to our list of the grasses of the United States. 
Orcuttia californica Vasey, Bull. Torrey Club 13: 219. pi. 60. 
1886. 
This species, known previously only from the type collection, from 
near San Quentin Bay, Lower California, has been recently collected 
in Goose Valley, California, by Miss Alice Eastwood (no. 1013). The 
type specimen was rather immature. Miss Eastwood's specimens are 
well-developed and show an elongated inflorescence 6 to 8 cm. long, 
with somewhat the aspect of Lolium muUiflorum. 
Eragrostis Barrelieri Daveau, Journ. de Bot. 8: 289. 1894. 
This species from the Mediterranean region is well established in 
Texas. It is allied to Eragrostis Eragrostis (L.) Karst. (E. minor Host) 
from which it differs in the linear many-flowered divergent spikelets 
and in the absence of glands on the foliage. The following specimens, 
all from Texas, are in the U. S. National Herbarium: Abilene, Tracy 
7917; Kerrville, Heller 1879, Hitchcock 5280, J. G. Smith in 1897; 
Llano, Smith in 1897; San Antonio, Hitchcock 5164; Kenedy, Hitch- 
cock 5341; Brownsville, Hitchcock 5428.
