PINACEAE 
Pinus edulis Hngelmann in Wislizenus Mem. North. 
Mex. (1848) 88. 
Pinon nuts were one of the most abundant plant re- 
mains found in the Bat Cave deposit. Many hundreds 
of broken shells were unearthed with a few whole nuts, 
several cones and an occasional twig. 
In strata I and II this species is represented by nuts 
and cone scales. The remains in stratum III include a 
twig with needles attached, as well as cones, cone scales 
and seeds. From stratum LV pinion is represented by 
both seeds and cone scales. In both strata V and VI 
abundant seeds, cones, cone scales and twigs were re- 
covered. 
Thus, P. edulis is represented during the entire period 
of occupation of Bat Cave. 
Pinus ponderosa Douglas ex P. Lawson, Agr. 
Man. (1836) 854. 
Remains of this tree were found only in strata V and 
VI. In stratum V ponderosa pine is represented by the 
ends of two twigs with the needles adherent. A number 
of separate needles and a cone were recovered from stra- 
tum VI. 
Pinus sp. 
Wood of a species of Pinus was found in all strata 
except I.
