Cystodium is a fern in its own family, Cystodiaceae.[2] It contains a single species: Cystodium sorbifolium (Sm.) J.Sm. 1841.[3] Because it looks like a small tree fern, it had previously been placed in the tree fern family Dicksoniaceae. Subsequent analysis had moved it to the Lindsaeaceae,[3] but the most recent phylogenetic studies have placed it in its own separate family, Cystodiaceae, with a sister relationship to the current Lindsaeaceae.[4]

Distribution

Cystodium is distributed through lowland rainforests from Borneo to New Guinea and nearby islands, as well as the Solomon Islands.[3]
