(Hartley.) cannot be any doubt that the close relationship of maize and teosinte points the way to the determi- nation of the botanical characters of the original wild corn plant. Recently, Montgomery has sug- gested a theory as to the nature of the maize ear, in which, in , he states "that corn and teosinte may have had a common origin, and that in the process of evolution the cluster of pistillate spikes in teosinte were developed from the lateral branches of a structure, while the corn ear developed from the central spike. It is probable that the progenitor of these plants was a large, much-branched grass, each branch be- ing terminated by a tas.^el - like structure, bearing hermaphro- dite ; [See lit- erature references at end of article.] The Zea canina of Mexico (first described in 1890, by Watson) is of great interest in studying the origin of corn. Bailey experi- mented with this plant and made hybrids with forms of cultivated maize. Without com- mitting himself as to the origin of Zea canina itself, he made the following observa- tions
