or variety of Euchlena mexicana? If the latter, then Zea 
canina becomes a mongrel plant. Or is Indian corn a species 
of Euchlena, closely related by consanguinity to Euchlena 
mexicana? ‘These questions can only be answered by the 
discovery of the wild plants concerned in the problem of the 
origin of maize.’ The following formule present the hypo- 
thetical position of the writer upon this question. Common 
names are used to prevent the confusion of synonyms. 
Teosinté 2 wild, crossed by the partially ameliorated pro- 
genitor of Maize (a species of Euchlena) § probably pro- 
duces the ordinary Indian Corn (Zea mays L.), and the 
second cross known by actual experiment to occur, viz: 
Euchlena mexicana Schrad. 2 X Zea mays L. & = Zeacan- 
zna Watson, the “ maiz de coyote”’ of the Mexicans. 
Until this purely theoretical view is established, it is the best 
and the safest course to pursue to keep closely to the known 
facts concerning these cereal plants, teosinté and maize, rele- 
gating theoretical considerations to the place kept for unestab- 
lished hypotheses, the botanical Gehenna.
