A soil which is lacking in plant food and not retentive of moisture, dwarfs the plants and they prematurely put out flowers. MALE OR STAMINATE FLOWERS.—Tassels. The male or staminate flowers are found in the tassel, arranged in the form of a panicle, the branches of which are shorter nearer the base. There are two single flowers in each spikelet. Each single flower has its own set of inner bracts, and the two together are enclosed by thicker, darker green, outer bracts. Each flow- er has three stamens, mounted at first upon short, stock fila- ments, but which as the pollen matures, lengthen and push the pollen sacks or anthers out to be caught in the breezes. The anthers are two-celled and in- stead of opening at the tip end, split just above and along one side. This allows the pollen grain to be wafted to greater distances. At the base of each set of these filaments, there is present a greenish, glandular, turgid body, called the lodiculc. which swells as maturity ad- vances, thus spreading open the bracts to allow the stamens to be pushed out. Each pollen gram is very small, having in its center a nucleus, while the remainder of the cell is light, and serves as a buoy in its course through the air. It has been estimated that each anther or pollen sac produces about 2,700 pollen grains. A single tassel con-. Section of branch of showing pollen sacs suspended on the elongated fila- ments.
