Lygodium is a small genus of climbing ferns with about 35 species, mostly with a pantropical distribution and with a few species extending into temperate areas (Flora Mesoamericana, 2019). The genus comes from the Greek word ‘lygodes’ meaning flexible, in reference to its twining rachis (Flora of North America, 2019). All species of the genus have an elongated climbing rachis with indefinite growth, often reaching lengths of several metres.
