Each ear is borne upon a shank which at first holds the shootupright along the side of the stalk, but, which, as a rule, later allowsthe matured ear to droop and even to hang, because of increasedweight of the ear and lack of rigidity in the shank itself. The shank. (By Courtesy of Iowa State College) Fig. 16. EAR IN NATURAL POSITION ON STALK. Note That Its Shank Lies in the Groove. The Outer Husks are Shorter Than the Inner Ones. fits in the groove of the internode and appears jointed just as does thestalk itself. As many as ten or more internodes are present. At eachnode a husk is produced, those from the lower nodes overlappingthose above. The number of husks and their coarseness dependsupon the season, the soil and the variety.

In a wet season, when the fibro-vascularbundles are constantly supplying plant food from below, shoots,so-called, may appear at seven or more nodes, beginning quite nearthe ground.
