From this showing it appears that in proportion to the partici- 
pation or predominance of the female element, just in that propor- 
tion does the plant decline in size and development, and we are 
forced to conclude, as we have shown in several other articles,* 
that females are undeveloped males, and this is true in plants as 
well as among animals. : 
In some cases where the female flowers were on the male pani- 
cle, instead of forming a single large ear, as was usually the’case, 
each branch of the panicle bore grains separately, which must 
have resembled what Bonafous mentions as a variety called Cy- 
mosa, which has its ears so crowded together that it is often called 
mais à bouquet. Some of the specimens examined by me had the 
appearance as if the col) had been separated into several segments, 
triangular in shape, bearing corn only on one side (the outer) of 
the triangle. 
Returning to those stalks bearing male flowers alone and which, 
I have said, are tallest, most rank, and best developed,—I would 
suggest that the absence of female flowers was due to retarded fe-
