|discussion=<p>The common stalk on this species tends to be reddish brown. The presence of extra sporangia on the proximal pinnae is known only in <i>Botrychium pedunculosum</i> and <i>B. ascendens</i>.</p><!--
--><p><i>Botrychium pedunculosum</i> grows with other moonworts, <i>B. lanceolatum</i>, <i>B. lunaria</i>, <i>B. minganense</i>, and <i>B. pinnatum</i>. It has not been found in association with the rather similar and much more common <i>B. hesperium</i>.</p><!--
