Wood of Quercus sp. was found to be most prevalent 
in stratum III where six specimens were recovered. This 
genus is represented by only one other wood specimen 
from stratum VI. 
It is not surprising to find Quercus remains in the Bat 
Cave deposit, as oaks grow in the area today in the 
better watered canyons. This further points to the great 
similarity of the past vegetation of the area to that of the 
present. It is unusual, though, that there should be so 
many acorn shells and no juniper remains in stratum 
III. At the time represented by this stratum there must 
have been a much greater abundance of oak in the area, 
which in turn would suggest a slightly higher rainfall 
than that of today. 
CHENOPODIACEAE 
Chenopodium sp. 
Remains belonging to this genus were found in stra- 
tum IV. 
Atriplex canescens (Pursh) Nuttall Gen. No. 
Amer. PI. 1 (1818) 197. 
Typical four-winged fruits of this plant were recovered 
from strata IV and VI. 
The shrubby members of the Chenopodiaceae are rep- 
resented by the wood of Atriplex (canescens?) and other 
woody material identifiable only to family. The former 
is a very common shrub of the area today. The Atriplex 
wood was found in stratum I, while the other material 
came from strata II, ILI, [IV and VI. 
Suaeda suffrutescens S. Watson in Proc. Amer. 
Acad. 9 (1874) 88. 
In strata I and V were found twigs of this plant.
