Transverse section of an intemode of a stem of Clematis, showing a ring of six larger and six smaller vascular strands, surrounding the central pith, and covered externally by the thick cortex. The collen- chyma massed at the projecting angles is dotted. (X15.) for them in the shoots of Dicotyledons. There arc differences in the number of the strands entering from each leaf in various examples. , In some there is only one strand, in others more. The arrangement of the leaves on the stem may also vary, as well as the distance.
