LOL. I got them at a local store in Holmdel NJ USA as unidentified terrarium plants. Sorry, I can't help more than that. I'll post here if I find a name.

Actinopteris semiflabellata - Eyelash Fern. - no too wet and they will do fine.
Wow! I've been told most of these are "resurrection" plants that have long dry spells in habitat when they dry to brown and curl up, only to unfold when the rain comes.
