|discussion=<p><i>Selaginella bigelovii</i> is a member of the series Arenicolae (R. M. Tryon 1955) and is closely related to <i>S. rupincola</i> (see discussion). It may be confused with <i>S.</i> × <i>neomexicana</i>. <i>Selaginella bigelovii</i>, however, always has well-developed megasporangia with most of the megaspores and microspores well formed, whereas <i>S.</i> × <i>neomexicana</i> is a presumed sterile hybrid that does not form megaspores, seldom forms microspores, and usually has most sporangia misshapen (R. M. Tryon 1955). Moreover, <i>S.</i> × <i>neomexicana</i> has not been reported from either California or Baja California.</p>
