Dictyostele. The vascular cylinder consists of a network of separate strands (
vascular bundles) which may appear circular in cross section (Figure 1.4d) or
scattered throughout the ground tissue (Figure 1.4e). The circular dictyostele is
found in ...

Siphonosteles with overlapping gaps are dictyosteles, and the intervening
portion of the vascular tissue lateral to two overlapping gaps is a meristele. When
there are numerous meristeles, the dictyostele looks like a cylindrical msshwork.

Like the dictyostele the vascular strands in the eustele are also interconnected. In
some cases the vascular strands are scattered and such a stele is called
atactostele (Nast, 1944 ;Esan 1953). It is found in the monocotyledons (Fig. 8.2).
