Long, wedge-shaped kernels like 9 and grain in proportion to cob. (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 - like structure, bearing hermaphro- dite flowers.' [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 (Cornell Bulletin No. 49, 1892) on its le relations to Indian corn (subsequent experiments have not been published): ' It may be worth while to inquire whether this Canina corn still retains a specific identity, whether it really is a distinc
