Of course, if the stamens are wanting in one kind of blos- ,5j som there must be others that have them. Plants of ,»ii. ^^.j^j^ imperfect flowers accordingly bear two sorts of blossoms, namely, one sort Staminate or Sterile, those having stamens only, and therefore not producing seed; and the other Pistillate or Fertile, having a pistil but no good sta- mens, and ripening seed only when fertilized by pollen from the sterile flowers. The Oak and Chestnut, Hemp, Moonseed, and Indian Corn are so. Fig. 165 is one of the staminate or sterile flowers of Indian Corn; these form the " tassel" at the top of the stem: their pollen falls upon the "silk,"' or styles, of the forming ear below, consisting of rows of pistillate flowers. Fig. 166 is one of these, with its very long style. The two kinds of flowers in this case are Monoecious; that is, both borne by the same individ- ual plant; as they are also in the Oak, Chestnut, Birch, &c. In other cases Dioecious; that is, when one tree or herb bears flowers with stamens only, and another flowers with pistils only ; as in Willows and Poplars, Hemp, and Moonseed. Fig. 167 is a staminate flower from one plant of Moon- seed, magnified; and Fig. 168, a pistillate flower, borne by a plant from a diflTerent root. There is a third way: some plants produce what are calle
