|discussion=<p>The range of <i>Lycopodium hickeyi</i> overlaps with that of <i>L. obscurum</i> and extends considerably north and west of that species. Although the arrangement of the leaf ranks is similar to that of <i>L. obscurum</i>, the leaf dimorphy and the ascending orientation and absence of twisting of the leaves are diagnostic. Where ranges of two or three species overlap, indivual species retain their identities, indicating that their critical differences have a genetic basis.</p>
