Cyclodium is entirely neotropical and contains about 10 species. The genus was revised by Alan Smith in 1986 [American Fern Journal 76: 2, pp. 56–98], who mentioned that this particular species is “the most widely distributed and variable of all cyclodiums”. In general, these plants can be recognized by creeping rhizomes, dimorphic fertile-sterile leaves, coriaceous blades, round sori (often confluent at maturity), and large peltate indusia.
