Phylogeny

The monophyletic genus Lecanopteris has been divided into two sub-genera, Lecanopteris and Myrmecopteris. All the species have rhizomes associated with ants. Subgenus Lecanopteris was monophyletic, and Myrmecopteris was paraphyletic.[2][3] A 2019 molecular phylogenetic study suggested that the genus was related to three other clades, treated as genera, related as shown in the following cladogram.[5]

Lecanopteris s.l.

Bosmania

Dendroconche

Zealandia

Lecanopteris s.s.

As of February 2020, the Checklist of Ferns and Lycophytes of the World recognizes the segregate genera; other sources do not.
