I have had this weed growing in a pot with the remains of a pineapple plant. It has been slow growing and I keep looking at trying to figure out what it is. Any ideas anyone?

Maybe a fern of some kind?

That was my thought when it first showed up, but there is now a stem and the leaves don't quite look "ferny" to me.

Apple pine.

Are these leaves part of one leaf or are they growing one by one? I've seen similar fern-like thingie, but it seems it has long stem. Wait and see, I guess.

Some of the leaves are fused together, some are not. I'm trying to decide if I should move it to a new pot and give it more light in case it turns out to be something I want. :?

I've now moved it to a small pot and am giving it more light. It it now putting up a new shoot which is unrolling in a fernlike manner.

There is a fern that is native to Ohio that grows like a vine. Weird!

I'm tenatively identifying it as some sort of Lygodium. Not sure if it is an import or the native one though.

Definitely a fern of some type. I will try and post a picture since it looks a whole lot different now. Meanwhile, several other things have sprouted in the pot, a shoot off the Pineapple and what I suspect if a Cypress Vine..

Finally got around to taking some pictures or it. Does anybody recognize this fern?

Wow, doesn't really look like fern. Perhaps fern that is a couple of millions age old. Photo from bit more distant position might be in place.
Are you sure it's fern? Does it unfold each "leaf" the way other ferns do it? At least around here, I haven't seen anything quite like it.

Yes, the fronds unfurl like other ferns do. Some of the fronds have a brown border which I am pretty sure are sporangia.

Could it be Asplenium rhizophyllum -Walking fern. I'm not sure about it's weird appearance with small and not really symmetric fronds. It does seem it's one of Asplenium ferns tho.

Post subject:  Re: Weird Weed

It doesn't match the description of Asplenium rhizophyllum. I'm thinking it might be some species of Lygodium.

I think I have a possible ID on the fern: Lygodium articulatum. I'm not 100% sure, but the "leaf" shape is right.

Post subject:  Re: Weird Weed

I'm still researching this from time to time. Fronds are getting longer and it looks like it is starting to change the leaf shape. This combined with what appears to be a lot of mis-identification of the various Lygodium species on websites is making things difficult. I'm hoping it turns out to be the native species rather than one of the invasive ones.
