The ligule has been appropriately called the rainguard, as it acts in such a way that rain- water with dust particles held in .solution, which runs down the grooved surface of the leaf, runs off on either side on reach- ing the ligule and does not run into the space between the stem and sheathing base, where dirt might other- wise easily accumulate. The folds in the margin and base of the leaf, which are formed because the edge grows more rapidly than the middle, are in- genious natural or mechanical contri- vances to ease the strain on the leaf- blade when the wind blows. If a microscopic section is made of the leaf-blade, peculiar cells are found distributed in the upper epider- mis between the prominent parallel veins. These are bulliform cells and in ordinary weather absorb water and. Fig. 601. Ears from the stalks shown in Fig. 600. desiccation and controls the normally high rate of transpiration, or water loss. Floivers.— The flowers of maize are arranged in clusters in two difl"erent parts of the plant. The male (staminate) flowers together form the termi- nal tassel of the plant, while the female (pistillate) flowers (Fig. 515) are placed on the cob, sur- rounded by the husks in the axils of the lower, or usually the middle leaves of the stem. The stami- nate flower cluster is known as a panicle of spike- lets. Each ultimate division of the tassel (pani- cle) is a spikelet. Each spikelet consists of two dry scales (lower glumes) subtending two flowers of three stamens each. Each staminate flower is surro
