Not sure what you mean by "long-leaved", it looks quite normal to me.

well, if it's normal ;) may be you can point me in the right direction? what kind of fern is it?
these look like real bi-pinnate leaves, not like long fronds on most ferns. i've seen a lot of ferns, but never like this. i went and found comprehensive books on ferns with pics and searched thru those - nada.
these are fairely large too - may be the scale is not apparent from the pic, i should've stuck my foot in it :).
i can't find any pic similar at all!

Stick your foot in it? I do that all the time without even trying, LOL. I found one that looks similar, but not the same, and that's Cyrtomium falcatum. There was another one I took a photo of a couple of years back, will have to try and dig out the photo. From memory it looked the same. If I can find it tonight I'll post it tomorrow. Ferns do come in an amazing array of shapes and sizes

Hi
Can't help with the ID but was wondering if they still have that fantastic silver joey palm in the RPH??
Fairchild is such an evil place .They show you all those fantastic plants and I have to track some down and kill them lol gary

no-no-no-O! it's not a holy fern..those have way too many pinnate leaves and they don't have wing tips on the last pair!
here, i did a close up of the left top corner, see those 'double' half-leaves that are attached on last pair? seems the last pair is always like that. and also see the top palmate juvie? leaf - that's wicked. it's pock-marked too like a juvie;).
holy ferns don't grow like that. and their leaves are usually more smooth, these are pleated a bit.
also notice there are no more then 5 leaves!: triple-center-1 pair- last wing tips. not on any one frond! may be it's still a young plant though and there could be more then 5?
and all juvies are pock-marked and palmate. like on syngonium sort of: first connected and then they split. but the last pair is growing 'horn' tips.
i must sound crazy :).
i should've asked the attendant - but half the time they are clueless! tropical fern is the most likely answer ...
gary,
i had to google RPH... and go search all my pics 3 years back - but i see no silver joey palm. did i miss it? where was it? with what other plants? i have a lot of pics from conservatory, but no palms...
so, there is another beauty to hunt down! thanks for telling me, LOL. i'll ask next time.
i do think that fairchild could make a killing if they propagated more of their plants for sale. you're close enough to actually go for their plant sale! with a truck!.

Hi
RPH= Rare plant house which is a GH/ conservatory whatever lol I was there before Andrew and the entire garden was devasted they did rebuild but haven't been inside for many years though I have attended the "Ramble "(sale) on several occasions . . I did attend the WOC (World orchid conference) and international aroid show . they raised the gate fee to 20 bucks and I hate driving in Miami so haven't gone in several years .
On one visit two palms caught my eye . Silver joey and Sealing wax. Couldn't live without them so began a long hopeless struggle . Still have the SJ but SW are long gone.lol
I've got over 25 nurseries within 20 miles of my house with no entry fee lol. Last purchases were a White elephant palm and and several epiphytes lol
getting old and cranky so now seeking "landscape type plants " no more hoisting plants in and out of the shadehouse lol Good luck with your ID gary

I did say " I found one that looks similar, but NOT the same". But the fern in your photo is either Tectaria heracleifolia or T. incisa. The T. heracleifolia is a native of Florida, the T. incisa is an invasive weed. However, the colder climate there wipes out a lot of the T. incisa in unprotected situations, whereas the native one is cold hardy. Because the one in the photo wasn't labelled there's a possibility it could be the weed one.

wow, you did it!
how did you find it?!
it's tectaria heracleifolia.
this is in rare plants conservatory of fairchild - so you figure they won't be growing weeds?
so i got a ref immediately, see link.
quote:
Broad halberd fern (Tectaria heracleifolia) is a tropical species whose global range include a handful of preserves in Miami-Dade County. We conducted augmentations of 234 Tectaria heracleifolia in 2011 and 2012. These ferns were planted in a preserve that was once the old Florida attraction "Orchid Jungle."
i just love it! thank you!
