Cyrtomium falcatum (L.f.) C.Presl — Fig. 3h

Origin — Exotic, introduced for ornamental purposes. Native to China, Japan and South Korea.

Habitat & Ecology — Terrestrial, it is occasionally epipetric and growing on walls.

Location within the reserve — A single population of this species was found growing in a shady area of the understory.

Observations — Due to its exotic origin, its traditional use as an ornamental species ( Yañez et al. 2020), and its growing close to Nephrolepis cordifolia , make it likely that the origin of this species in the area could also be linked to the anthropogenic use of the reserve area prior to its foundation. Previous work has recorded its potential to colonize new habitats and displace native species ( Robinson 2009).
