Cynodon dact, ve 
everal plants were seen at the Sand Hills, where it seems to be 
naturalized. I saw fine lawns of it at Fort Davis, Marfa, and 
El Paso. 
Chloris eens 
nin the gravelly soils of the valleys. Frequent at the 
Sand Hills. 
Chloris elegans. 
Common on the bottom lands of the creeks. 
Tr ese! verticillatas 
n at several poiits alony the Rio Grande, generally in clumps. 
as seen in places along Toyah Creek. On the Pecos flats I 
saw a few plants mixed with S. airoides. It seems to thrive on 
alkaline soil. 
sail 0 Mee gostachya (Blue grama). 
well-known grass, so abundant in these western regions, is 
seen in its greatest perfection on the high prairies, covering 
extensive areas. Mixed with some of the other gramas, it oc- 
curs on the grassy slopes and in wide, gravelly spaces on the 
: mountain-sides. Unlike many of the mountain grasses, the gra- 
= mas are not at their best on the craggy slopes. In many locali- 
ties the best hay is furnished by a mixture of this and other 
gramas. 
Boutcloua hirsuta (Black grama). 
This, with a more extensive range (extending eastward beyond 
the Brazos, in East Texas), is inuch less abundant than the 
blue grama. In some places it is largely mixed with other 
gramas. Several specimens were seen at the Sand Hills, 
Bouteloua Havardii., ~ 
een in a few places in the Limpia region, and near Musquis 
Caiion ; also at some of the foot-hills on the north side of the 
Chenates, and at Paisano. 
Bouteloua eriopoda (Woolly-jointed grama). 
e most common grasses in the Chenate region. On the 
lower ridges and prairies just north of the mountains it is gen- 
erally the prevailing grass, covering large areas. In the gorges 
of the Chenates, on some of the grassy spots, this and the fol- 
lowing (B. stricta) constitute the principal growth. On the 
high prairies it is occasionally found mixed with the blue 
grama. It is frequent in the Limpia and other mountain re- 
gions. Several specimens were seen at the Sand Hills. 
Bouteloua stricta. 
Common in several portions of the Chenate region. Seen in 
abundance on some of the lower ridges at the southern base 
of the mountains.
