Corn has been successfully crossed with teosinte and the progeny resembles both parents. From the study of these interesting variations Professor Montgomery has explained the origin of the corn plant in the following way: The ancestors of the corn plant were probably plants hav- ing many branches like teosinte, and were the result of a cross of teosinte on some similar plant, or the progeny of a sport of teosinte crossed with the common

In either case the original corn plant had branches coming from the axils of the leaves. At the end of these branches were tassels similar to those found on field corn. They differed from the corn tassel in that both male and female flowers were pro- duced, and after fertilization grains developed. Thus the occasional plant that we find in a field of corn having grains in the tassel is a reversion to the original form. At first both male and female flowers were produced in the tassel of each branch. But the highest tassel, the one on the main stalk, was not well located to receive pollen, since the pollen would naturally be carried downward, while those on the lower branches were in a favorable position to receive pollen but not in a.
