The sap bundles of the corn stem are isolated and of the closed collateral tyi)e. Leaves.—The leaves of corn are two-ranked; that is, they alternate on opposite sides of the stems. Each leaf may be divided into three parts,—a sheath, which is open along one side, a ligule, or f^^ keep the leaf-blade perfectly flat. In hot, dry weather, water is lost from these cells and the leaf-blade rolls up and thus protects itself against. Fig. 600. High northern corn.

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 oft' 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 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 fan-shaped cells are found distributed in the upper epider- mis between the prominent paralle
