Mutisia, thank you for posting these silver-leaved relatives of our green Maidenhair fern*, common to our eastern woodlands in Maryland. I just never imagined that our go-to fern for dark, mossy trails that so rarely saw a ray of sunlight in some places, had a silver-leaved relative somewhere growing in full, blazing sun.

Thanks for your kind words, Bluespiral.

This is one of several endemic Adiantum species we have. As in the USA, our Adiantums thrive in humid shade. The area where I took these pictures (at the foot of The Andes mountains) originally had tall trees, that were removed in order to sell the land and build a condo That's why the ferns were exposed to fulll sun. I was able to visit the place for a few years and observed the ferns that had died back as soon as it got to hot, came back with the first autumn rains.
