This fern was a volunteer in one of my terrariums. Much to my surprise, it has handle the transition from my terr to dry air of my apt (I'm lucky if I can get the humidity up to 30%) incredibly well. The fronds have changed, developing more pinnae/leaflets with each succeeding frond.

The leaves have a grayish/silvery cast to them when the light hits them just right. The petioles are mainly green, the rhizome is covered with a reddish-brown 'fur'
