Furthermore, the Plate may be Divided into separate bundles called Meristeles . Meri means to divide. Thus, Selaginella may have a divided stele. These appear to be separate but coalesce and are interconnected periodically along the axis of the stem. We will say that Selaginella has a Protostele.
Roots arise at branch points along the stem.
They have been called rhizophores because they don't look exactly like roots until they contact the soil. However, they are roots nonetheless. They branch dichotomously and have a Haplostele . The Vascular Tissues are similar to those of Lycopodium . Labeled Unlabeled Rhizome Cross Section with Extensive Sclerenchyma Development - Note the Leaf Traces which originate from the Stele Labeled Unlabeled Selaginella Stem Section with Prominent Sclerenchyma in the Cortex .
