The Plectostele definition is as follows:
- It is a club moss in which the xylem components are governed usually in parallel plates.
- Plectostele is a variety of protostele in which xylem plates shift with phloem plates. Eg. Lycopodium clavatum.
- a protostele in which plate-like areas of xylem seem in transverse section encompassed by phloem tissue, thus arising to form shifting bands. These discrete plates are connected in longitudinal types. Few recent club mosses have plectosteles in their stems.
