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] A fossil species of the genus Cystodium sorbifolioides is known from the Cenomanian aged Burmese amber in Myanmar. [5]
Cystodium is distributed through lowland rainforests from Borneo to New Guinea and nearby islands, as well as the Solomon Islands. [3]
