Text-book of botany, morphological and physiological . ni //, with a young(asexual) plant, w its first root, bb its leaf-sheaths (X 10). ^f^ VA SC ULA R CR YPTOGA MS. end each bundle splits into two short diverging arms, by which it unites with thetwo neighbouring bundles of the next lower internode, where they descend intoit from their sheath-teeth. The joints of the stem and their leaf-sheaths thereforealternate; and since in each joint the arrangement of bundles, leaf-teeth, projectinglongitudinal ridges, and depressions or furrows, is exactly repeated in the transversesection, the different parts of a joint always correspond to the intervals betweenthe homologous parts of the next upper and next lower joint. If the internodehas projecting longitudinal ridges on its surface, one of these always runs down-wards from the apex of each leaf-tooth parallel with the others as far as thebase of the internode ; between each pair of leaf-teeth commences a furrow orchannel, which also continues as far as the base of the internode.
