Polypodium ryanii

A little-documented polypody fern from the Leeward Islands of the Lesser Antilles, with no wild occurrence records online. Treat it like other Antillean montane polypods: an epiphyte or rock-dweller of humid forest that wants dappled light, steady warmth, high humidity and a fast-draining mount or mix.

Where it grows wild

No habitat data is published for this species. Polypodium and its relatives in the Leeward Islands grow mainly on trunks, branches and mossy rocks in humid montane rainforest on the volcanic peaks, so that is assumed here.

Not recorded. Ferns of this kind on the Leeward Islands mostly grow in montane forest, roughly 400 to 1,200 m, rather than at the coast.
