Here each leal sends down two âAfterTstageii. bundles, which pass through two internodes and then unite with other descending bundles at their middle points. The fibro- Tascular 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 piairs of leavesâ, those at its summit and those at the sum- mit of the one above.
