It is the general opinion that corms which have been al- lowed to bloom every year for three or four years become thinner and thinner. Soon after the base of the growing stem of the Gladiolus has begun to thicken, small corms are found to have formed be- tween the old and the new corm. These are properly called cormels. (See fig. 40.) They are covered with a hard shell, thus differing from seedling Gladioli of the same size, which have a covering more like a husk, composed of the dried bases of the previous season's leaves. A more rapid method of multiplying new varieties is to cut the corm into several pieces so that each piece has one or more eyes. Other examples of corms are Crocus, Cyclamen, Antholyza, Col- chicum. Arum, Ari isnia, Ixia, Montbretia, Morsea, Sparaxis, Tigridia, Watsoriia (For additional list see page 141). TUBERS AND TUBEROUS ROOTS Certain plants produce thickened portions of their stems beneath the soil. These are tubers.
