WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 1138 
first merely spreading, in age twisted at the base and bent at right angles to 
the glume. 
Type in the U. S. National Herbarium, no. 690259, collected on Tortugas 
Mountain, Dona Ana County, October 6, 1904, by E. O. Wooton. 
ADDITIONAL SPECIMENS EXAMINED: Tortugas Mountain, October 22, 1892, 
Wooton 1087. 
Lloyd’s 195, from foothills near Hacienda de Cedros, Mazapil, Zacatecas, 
Mexico, collected in 1908, is probably the same species. " 
In the type locality the species is associated with several others of the genus. 
It somewhat resembles A. vaseyi, with which it is found, but may be recognized 
by the spreading panicle with its numerous spikelets and by the widely diverg- 
ent awns.

Our New Mexican material exactly matches the type (Reverchon’s plant), 
and some of it has been referred to A. reverchoni by various students of the 
genus. It is probably a distinct species. There seems to be a typographical 
error in the original publication, the name being printed augusta, not angusta, 
as Doctor Vasey doubtless intended. 
In order to avoid the use of a name about which there is some uncertainty, 
and at the same time to give the plant the specific rank it certainly deserves, 
we dedicate it to Dr. George Vasey, who was for years a careful student of the 
grasses of the southwestern region and first recognized this plant as distinct. 
This may prove to be A. fasciculata Torr., described from material collected 
by Doctor James in the “forests of the Canadian,” a locality somewhere in 
northeastern New Mexico. We have been unable to compare our material with 
the type of that species or with authentic specimens, 
CONVALLARIACEAE. 
Salomonia cobrensis Wooton & Standley, sp. nov. 
Rootstocks slender; stems slender, somewhaj flexuous, 20 to 40 cm. high, 
glabrous; leaf blades elliptic, 50 to 95 mm. long, 10 to 82 mm. wide, acute, nar- 
rowed at the base into a broad petiole 3 or 4 mm. long, glabrous, slightly paler 
beneath, very faintly nerved, none of the nerves prominent except the midrib; 
peduncles strongly and sharply deflexed, 10 to 15 mm. long, each dividing into 
2 or 3 slightly shorter pedicels, these stout and strongly flattened laterally, 
glabrous; perianth 12 to 19 mm. long, tubular, somewhat expanded toward the 
mouth, the lobes oblong, obtuse, twice as long as the tube; anthers 6 mm. long, 
acute, slightly exceeding the almost filiform, slightly roughened filaments; no 
mature fruit seen, but that present about 6 mm. in diameter. 
Type in the U. 8. National Herbarium, no. 36170, collected in June at the 
Copper Mines (Santa Rita) by Dr. J. M. Bigelow (Mexican Boundary Survey 
no. 1478).
