Where it grows wild

Forest floor and banks in montane rain and cloud forest; specifics for this species are thin, so the picture is drawn from the measured sites and typical montane Blechnum habitat.

Records span 850–1400 m in practice (median 1158 m); a single 4100 m record is impossible for Cuba or Jamaica and is ignored.
