|discussion=<p>A related taxon, <i>Dryopteris intermedia</i> subsp. maderensis (J. Milde ex Alston) Fraser-Jenkins, occurs on eastern Atlantic islands.</p><!--
--><p><i>Dryopteris intermedia</i> and the other taxa in the " D. spinulosa complex" have long confounded taxonomists. <i>Dryopteris intermedia</i> is diploid and is one of the parents of the allotetraploids <i>D. carthusiana</i> and <i>D. campyloptera</i>. <i>Dryopteris intermedia</i> hybridizes with eight species. All hybrids are easily detected by the distinctive glandular hairs on the indusia and, usually, on the costae and costules.</p>
