Help with identifying this palm I have had for a while and lost track of what it is. Location Coconut Grove, Miami Zone 11A At least 15 years in ground with hardly any trunk but flowering this year.

I'm not much help, but that might be the longest forum topic I've ever read and I'm also on Reddit. It's gorgeous though.

Ceroxylon?

[idontknowhatnametuse]

Or maybe Allagoptera caudescens

It does resemble one but Ceroxylon would have 0% chance of survival in Miami zone 11a.

The bronze undersides of the leaflets remind me of arenga. But if the inflorescence is not terminal then I’m probably wrong.

Whatever it is, it’s actually quite beautiful . I love the contrast between the top of bottom of the leaves.

Maybe attalea of some sort🤔🤔 do you remembered you bought it from

Not alogoptrea.

It looks like Allagoptera caudescens ? but I could be wrong

[Xenon]

Some kind of super rare Ravenea? R. hypoleuca? I really want to know what this is

The Buru palm has a green and white zebra strip pattern on the new spear so not caudescens gyuseppe. I have them in my garden.

Richard, I had one, but it only had two leaves, which were seed-grown. That's why I added them (maybe?).
Anyway, thanks, I learned something else.

They are a lovely palm and tough with cool tolerance.

My first thought was orania palindan, cuz it looks a lot like mine and loves heat so that area should be ideal for it temp wise.  Not sure though, just a thought

Thank you all for the help.

I think I am still searching for the identify as none of the suggestions seem exactly correct.

What the photos do not capture is that the fronds are a good 10 feet long and almost 3 feet wide at their widest.  I also do not think that there will ever be a tall trunk, if any.  But I may be wrong.

To answer the question as to where I purchased the palm, I am sure it was in a 3 gallon container purchased at either the IPS Palm Sale at Fairchild or at one of Jeff Searles' plant sales back in the day.

Thanks again all.

I’m with Allagoptera caudescens. Fronds and the flower spike are consistent. I’d guess the spear just hasn’t been shown in the photos at the right angle to show the pattern. I’m not sure what else it could be and all other traits are consistent.

If its not Allegoptera the next time the botanist meet they will put it in the Allegoptera family!!!

[Coconut]

OK all.  After some on-line research with all the suggestions above I think Allegopetra caudescense must be correct.

I was initially skeptical as I previously had an Allegopetra species and it had no resemblance to this palm.  It was much smaller, less upright and the leaflets were more spiraled around the rachis.  In this palm the leaflets are very flat against the rachis. And the fronds are huge and upright.

That said, I stumbled upon fotos of Polyandrococos caudescense (now Allegopetera) and the position of the leaflets was exactly as they are on my palm.

Thank you all for your help.  Actually each suggestion helped me come to this conclusion.

It is Allagoptera caudescens, but when it was obtained 15 years ago it was probably tagged under its old genus, Polyandrococos caudescens. It is unlike the other smaller members of Allagoptera, due to the signature trunk. I think it was lumped in due to the inflorescence. The species was more popular when it had its own genus.

I think some of the old timers disagree that it should have been moved to Allegoptera if you want to buy one from Jeff you need to look under polyandorcocus!!

[happypalms]

A close up of the spear will confirm if it Is polyandrococos.

I'd like to have as many palm trees as possible. But I still have a lot left to collect.
