Each ovary contains a minute egg, called the ovule, which, on fertilization by the nucleus of the pollen-grain, develops into a seed. The cob does not complete its growth lengthwise before the first silks are ready for pol- lination. If the growth of the plant is checked through lack of sufficient moisture or plant- food, or inclemency of the season, the tip of the ear fails to grow out, and the cob, in- stead of being almost cylindri- cal, may remain tapering in shape through lack of develop- ment. In "pod maize" (variety tunicata) the glumes are large, completely enclosing the ovary and persisting around the ripe grain (Fig. 51). In the varieties usually under cultivation, how- ever, the glumes, valve, and palea (11 73J of the female flower cease to function, and are reduced to small rudiments around the base of the carpel. The position of the ear on the stem varies greatly in in- dividual plants according to the particular node from which the shank (iT 81) is developed, and according to the length of the several internodes below it.
