|discussion=<p><i>Cheiroglossa</i>, which is sometimes treated as a subgenus of <i>Ophioglossum</i>, is widely divergent from <i>Ophioglossum</i> in many characteristics, including the epiphytic habit, dichotomous roots, hairy stem apex, pendent and very large trophophore, palmately lobed blade, extremely large areoles, sporophores multiple and arising from sides of blade base, and the much branched gametophytes.</p><!--
