Katalapi Park (or Parque Katalapi) has 28 hectares of forest and open space with high diversity of ferns and a canopy reaching 30 metres - sounds like good epiphyte country to me!
Here are some of their epiphytic species:
Found from the coast to 2000 m above sea level, growing on logs or the ground. Fronds are 7-15 cm long.
Endemic to Chile, this fern is a low epiphyte and is found from 5 to 900 m. Dark green leaves reach up to 30 cm in length.
Also endemic to Chile, this species occurs from 2 to 410 metres. Fronds reach 20 cm in length.
Occuring between 5 and 1250 metres, this fern has a thick fleshy rhizome and glabrous leaves tht reach up to 46 cm in length.
