Discusión taxonómica
Selaginella novoleonensis is distinguished from S. lepidophylla by the former having median leaves long-acuminate to aristate (vs. acute to mucronate), leaf margins narrowly hyaline (ca. 0.05 mm wide vs. broadly, ca. 0.1 mm), and the median leaf bases and stems with hairs short, frequently inconspicuous (vs. long, conspicuous).A
