The cat-tail is a common plant in marshes. (See Figure 101.) Its flowers are about as simple as any. They have no perianth and they are of the two kinds, staminate and pistillate. That part of the plant which is supposed to look like a cat's tail is composed of separate carpels and stamens which grow very close together. The stamens are on the upper part of the tail. They die after they have shed their pollen. You may have noticed this dead part sticking out of the top of a mature cat-taiL Corn is another common plant which has diclinous flowers. The tassel of corn, which appears at the top of the plant, is composed of staminate flowers (see Figure 102), while the undeveloped ear is composed of pistillate flowers. The threads of the silk, which hang out from the young ear, are nothing but unusually long styles and stigmas. (See Figure 103.) Each style leads to an ovary. These ovaries are the undeveloped grains of corn. Pollen is produced in great abundance in the tassel. Some of it. Fig. 102. — The tassel of corn. Note the hanging anthers which are full of pollen. The pollen is scattered by the wind. —After Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Coulter, John G.
