... found in siphonosteles (Figure 1.9). They are discontinuities in the vascular cylinder that occur where leaf traces (the vascular bundles supplying leaves) depart from the stele. If you were to ... traces simply diverge from the solid vascular cylinder. The areas between the vascular bundles in a eustele are not leaf gaps. In eusteles, leaf traces arise from individual vascular bundles as if they ...
