Pollo. 
In all of its ear characteristics, this specimen is similar 
to modern Pollo except that it is smaller in most of its 
parts. [t is more primitive than modern Pollo in having 
a lower kernel-row number, a more slender rachis, and 
longer rachillae and glumes. As in Pollo, the kernels 
are rounded,

A photograph of this cob (with its ear cross-section 
diagram) is shown in Plate XVI. 
Measurements were made also on the seventeen cob 
fragments, and these are set forth in Table II. The length 
of the fragment divided by the number of spaces once 
occupied by kernels shows the average amount of space
