Here each leaf sends down two âAftei-T>rageii. bundles, which pass through two internodes and then unite with other descending bundles at their middle points. The fibro- vascular cylinder is thus compos- ed when complete of repeatedly branching bundles. A cross-sec- tion (Fig. 318) through the stem at some distance above the lower leaves in Fig. 317 shows that each internode c o n - tains bundles from two pairs of leavesâ, those at its summit and those at the sum- mit of the one above. In Fig. 318 the pairs of bundles marked c and d descend from the leaves c and d, while those marked e and/ pass down from the leaves one intemode Fig. 317.âDiagram showing the ar- higher Up. rangement f)f the fibro-vasciuar bun- t . ., - ,-, dies in stadiys angustifoUm. a, 6, in a Similarly Constructed dia- â d.
