Abstract
In the seedling of B. distachyum the first internodes are long, the axis is small in diam., and there are few vascular bundles. These characteristics aid in understanding the development of the vascular pattern of the first few internodes and its relationship to the developing leaves. The main vascular bundles of the young leaf are continuous with those of the central cylinder of the axis. External to the vascular ring of the axis are smaller bundles, some of which end blindly in the cortex and others which unite with the outer part of the vascular ring. These bundles are apparently downward extensions of leaf bundles. Above its divergence from the axis the young leaf has additional bundles which are not continued into the axis. This indicates that the vascular bundles develop first in the leaf and then develop downward into the stem. As more leaves develop the vascular bundles of the stem increase in number since leaf traces may extend through several internodes and since succeeding leaves are larger and have more vascular bundles.
