The Monocotyledones, so called since the em- bryo has alternate leaves, of which the first one developed is called a cotyledon, are also called Endogenae, or Endo- genous plants. A transverse section of the stem (Fig. 281) shows that the fibro- vascular bundles are isolated, numerous, zsi and scattered irregularly throughout the pith or funda- mental tissue. Each bundle is closed; that is, there is no zone of meristem tissue (cambium) between the xylem and phloem when these have reached their maturity, or passed over into permanent tissue. In consequence of this limitation of growth of the bundles, the plants are generally short-lived. In very young plants, where the fibro-vascular bundles are as yet few, their general disposition, or arrange- ment, may be seen. In the " Palm type," which is illustrated in the accompanying diagram (Fig. 282), the leaves supposed to be opposite, and their bases united with the entire circumference of the stem. The numerous bundles from each leaf pass obliquely into the stem, and then descend through the latter. The middle.
