Discusión taxonómica
Selaginella schizobasis, S. eurynota, and S. sertata (series Articulatae) form a poorly resolved complex with peltate median leaves. Selaginella schizobasis bears rhizophores along most of its stem length and occasionally has flagelliform stem apices. It is distinguishable by its oblong-elliptic lateral leaves, which are widest at middle, and by its axillary leaves with divergent auricles.A
