Note
Selaginella rhodostachya can be recognised chiefly by its microphylls ovate to ovate-elliptic with an obtuse apex, lateral microphylls with margins entire to slightly serrulate only acroscopically, dorsal microphylls with margins long-ciliate in the inner portion of the apical half, and midribs prominent. The megaspore surfaces are irregularly and slightly granulated; the microspore surfaces are covered with dense and interconnected verrucae. This is a very polymorphic species, probably constituting a complex. In Brazil Selaginella rhodostachya is most similar to S. microdonta A. C. Sm., but differs chiefly by its dorsal microphylls each with an obtuse (vs acute to short-aristate) apex. Morphometric studies, as well as palynological and molecular studies, are needed to clarify the circum­scription of this species.
