Phenology: Spores

Comments: The stems are jointed (articulated) and spores are formed in sporangia borne by the sporophylls (dark, more or less hexagonal at the surface) that are grouped to form the strobili at the tips of the stems. The leaves are very small and joined at their bases to form a dark collar at each node on the stem.
