Angiopteris evecta (giant fern or king fern)

Angiopteris evecta the giant or king fern is one of the largest ferns on the planet, not in height, but certainly in the size of its leaves

Angiopteris evecta is a giant, primeval-looking fern that produces massive, globular trunks and gigantic leaves.

The giant fern is native to Indonesia, New Guinea, coastal northern Australia and the south and west Pacific Islands.

Angiopteris evecta is found in terrestrial rainforests, clearings and along roadsides, also in ravines and on steep volcanic slopes, always growing in very rich soils.
