|discussion=<p>Selaginella lepidophylla Mettenius is a misapplied name.</p><!--
--><p>The long-bristled leaf apex of Selaginella pilifera is unique among New World xerophytic members of subg. Stachygynandrum series Circinatae Spring. The closest relative of S. pilifera is S. gypsophila A. R. Smith & T. Reeves, which is from Nuevo León, Mexico, and differs by having obtuse leaf apices. Further studies are needed to determine whether S. gypsophila represents a well-differentiated species or an environmental variant of S. pilifera.</p><!--
