SPIKES OF PERENNIAL TEOSINTE CONTAMINATED WITH MAIZE 



Here are shown, natural size, pistillate spikes of the perennial form of teosinte from the state 

 of Jalisco, Mexico, which have been contaminated by maize or Indian corn. A sure indication 

 of maize ancestry is the crowding of the segments, and the consequent forcing of the jomts into a 

 zigzag position. (Fig. 7.)
