Discusión taxonómica
Resembling S. oaxacana and S. cuneata in general habit, S. illecebrosa differs in leaves that are ciliate at their bases, lack idioblasts, and are silvery beneath, and in long-aristate median leaves. The orange-yellow microspores, exauriculate and entiremargined median leaves (except for a few long cilia), and appressed lateral stem leaves of S. illecebrosa distinguish it from S. mosorongensis. Selaginella mickelii differs in having leaves ciliate along their entire margin, ciliate sporophylls, and stems often flagelliform.A
