    Taxonomy

    The division of the subfamily Microsoroideae into genera has long been uncertain. A 2019 molecular phylogenetic study suggested that there were three clades close to Lecanopteris sensu stricto and distinct from other clades in the subfamily. The authors of the study preferred to set up three extra monophyletic genera, rather than use a broader circumscription of Lecanopteris. The genera are related as shown in the following cladogram.[2]

    Lecanopteris s.l.

    Bosmania

    Dendroconche

    Zealandia

    Lecanopteris s.s.

    As of February 2020, the Checklist of Ferns and Lycophytes of the World recognized the segregate genera, including Zealandia;[1] other sources did not.[3]
