Lecanopteris is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] They have swollen hollow rhizomes that provide homes for symbiotic ants. All are epiphytic plants that naturally occur from Southeast Asia to New Guinea.[2][3] Several species are in commerce,[4] being grown as houseplants and greenhouse curiosities.

Taxonomy

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]
