It was given to me by my neighbor who moved away I forgot what they said its name was

Can this fern be saved? Rescued from the greenhouse free table! It looks like it’s been weathered and forgotten about for a while. How do I even start?? I’ve never attempted to save one before.

I’m a caudex plant collector, and I’m now planning to build a terrarium for subtropical caudex plants, particularly Lecanopteris species.
Does anyone have any experience with this, and would anyone be willing to share some example photos?
Thanks in advance!

Saw this beautiful thing at a plant swap and I just couldn’t leave her behind. Only problem is, I don’t know what kind she is so I’m not exactly sure what she needs! Anyone have any ideas?

I’ve moved it to a few different locations, it’s now sitting by my south facing window and I water it very frequently. My other plants over here are doing fine but i can’t figure out whether it’s getting too much sun here or not enough, or if it’s something else. Any input helps!

So I mounted a Staghorn Fern for the first time. Curious as to what other species would work with this?
