It is well known that new stems are sent up hy the roots of Poplais and of Apple trees, for example, espcicially if the roots have been injured. These cases must be regarded as abnormal. 132.*you will remember that in our examination of somi'i"iari/ roots. In Monocotyledons the primary root is but very slightly developed, the fibrous roots character- istic of these plants bursting forth fi'oni the sides of the radicle at an early period of growth. In other plants the primary root either assumes Fig. 123. the form of a distinct central axis larger than any of it i branches, and called a tap-root (Fig. 123), examples of which are furnished by the Mallow, the Carrot, and the Fig. 122.—Magnified tip of Hyacinth root; a, the root-cap.
