Aristida dispersa. 
In the same localities as the preceding and in like soils and situ- 
ations, 
Aristida Palmeri. 
Several specimens of this were seen scattered about on the lower 
ridges and mesas in the Limpia region and in the Chenates. 
Aristida purpurea. 
Different forms of this were seen near many of the creeks and 
on the slopes of the lower ridges. 
Aristida Tavardii. 
his was seen in a few places on the lower mesas at the south- 
ern base of the Chenate Mountains. 
Aristida. 
On the prairie extending south of Marfa I saw several plants of 
this scattered here and there. At the southern edge of the 
Staked Plains, about Odessa, it is the most prevalent grass, 
known as the “ White grama.” 
Aristida Schiediana. 
Seen at several places in the neighborhood of Musquis and in the 
Limpia region. Growing like other grasses on the craggy 
slopes in the gravelly soil between the rocks and bowlders. 
Stipa suet n. Sp. 
n only on some of the lower mesas near cae ncioks Creek. Grow- 
ing in clumps in abundance. 
Oryzopsis fimbriata. 
Seen in a ise re on the craggy slopes in the Limpia region 
and at Pai 
Muhlenbergia fede 
Frequent on the mesas and high prairies. On the low prairie at 
Toyah Creek I saw several specimens. 
Muhlenbergia arenicola. 
Common on the high prairie between Fort Davis and the Chen- 
ates. 
Muhlenbergia monticola, 
everal clumps of this I saw scattered about on the craggy slopes 
in the Limpia region. 
Muhlenbergia spiciformis. 
nin the same localities of the preceding, also at Musquis 
Caiion. It offers a rare exception among grasses in its choice 
of habitation. I found it nowhere on the gravelly slopes. All 
the specimens I saw were growing on the steep sides of ledges, 
sometimes on very narrow shelvy places on the side of a steep — 
cliff; often in fissures of the rock, with no soil apparently for 
its Goaviek ment.
