|discussion=<p>R. M. Tryon (1955) reported an elevation range of 1500–4660 m for <i>Selaginella standleyi</i>. I have not seen specimens from these lower and higher elevations.</p><!--
--><p><i>Selaginella standleyi</i> is a member of the <i>S. densa</i> complex. It has sometimes been confused with <i>S. watsonii</i> and <i>S. sibirica</i>; it is, however, rather easy to distinguish by leaf and strobilus characters.</p>
