Ears of Corn-Teosinte Hybrid
These ears, as will be seen, have departed very radically from the snake-rattle type of the original Teosinte. On the other hand they quite obviously lack a good deal of conforming to the accepted standards of the developed corn. They have peculiar interest as representing another stage of the evolution through which the plant doubtless passed in the course of its development, under guidance of the aborigines of southwestern America.
