About

Argyrochosma chilensis is a fern endemic to the Juan Fernández Islands off the coast of Chile. It has leathery, thrice-divided leaves with dark brown axes; the leaves are coated with white powder below. First described as a species in 1853, it was transferred to the new genus Argyrochosma in 1987.

How to grow it

The horticulturist George Schneider considered the species suitable for greenhouse cultivation. He likewise included Notholaena hookeri, now thought to be a synonym of A. chilensis.
