Discusión taxonómica
Selaginella lepidophylla is at the center of a species group that includes S. nothohybrida and S. novoleonensis, and S. ribae (which see for discussion). Selaginella convoluta is another rosetteforming species that curls inward when dry, but it has median leaves with non-whitened and short-ciliate margins.A
