Another Evidence of Old Heredity
Here we see a corn plant bearing a complete, although very primitive, ear in the midst of its pollen-tassel. All the other familiar cereals except the corn bear their seed bracts in this way. Corn has developed the habit of bearing only the pollen tassel at the top, placing the seed-head lower down on the stalk, where the stalk has strength to support it. This specimen shows an interesting reversion to the primitive type.
