Prare IX. A. Cobs of Tripsacoid Chapalote from 
the upper level of the Guerra phase, ca. 1400-1200 
B.C. This maize, the predominating type in the 
cave, has indurated tissues of the rachises and lower 
glumes. When the other floral parts are lost the 
cobs with their stiff, often curved, lower glumes 
resemble a coarse file or rasp. The specimen at 
left still bears three kernels which have the brown 
pericarp color and round shape characteristic of 
Chapalote. Actual size. B. Cobs of Palomero Jalis- 
ciense, a popcorn race related to Palomero Tolu- 
queno, one of the four Ancient Indigenous races of 
Mexico. Palomero Jalisciense is known today only 
in the state of Jalisco. Actual size.
