Selaginella produces a peculiar leafless, prop-like cylindrical, structures, originate from the stem at the point of branching. These grow downwards into the surface and form many adventitious roots at their free ends which are  known as rhizophores. And the conclusion is reached that the seed deserves to be removed from Cardiocarpon, chiefly on account of its vascular structure.

They can be considered as roots because they can give rise to leafy branches. A characteristic feature of Selaginella is the rhizophore.

It is like an assisted structure which may originate from a branching point and branch out in two ways after making a contact with a hard surface or the soil.

Rhizophores are widely noticed in climbing species of many plants. To be true in every sense, a rhizophore is supposed to be a root.

However, on many occasions, it may give rise to leafy branches in case the normal branches are not there.

Selaginella may also display Anisophylly characteristic in which there can be leaves of two sizes in a plant. This mostly happens in species that are abundant in wet tropical areas.
