The vascular rays of old, thick stems of E. campylopoda differ greatly from the known ray structure found in young stems of the same species, and from the common ray structure of other woody species. The large rays in thick stems include xylem in various orientations, and they intermingle with the axial system. We suggest that this is a variant secondary growth, a common characteristic of climbers.
