Please help me ID this palm

[Jimbean]

I have an idea, but I want to get other takes.

Habitat photo? If so, where? My brain is going from Prestoea to Kentiopsis to Archontophoenix…

[Looking Glass]

I know what you are going for here..  Majesty Palm….  But it doesn’t look right.  Petioles come right out of the ground.   Majesty and Archontophoenix have like a little stem the baby fronds come off.

Looks typical of Chambeyronia oliviformis at that size to me, but I couldn’t exclude other species which can look similar at this age.

@Jimbean flip a leaf or two so we can see underneath. Looks a lot like an Archontophoenix.

I thought it was a majesty palm.  The fronds had that texture, but one of the experts on inaturalist thought it was a Dypsis spp

[Frond-friend42]

I think the C. Oliviformis.

It does look a lot like a young one.  The presence of a heel would help.   Can’t clearly see one.  The only thing is that these are relatively rare palms in yards, overall.  So playing the probabilities, it’s likely a more common yard palm, but I agree it looks very Dypsis/Chrysalidocarpus- like, the way the petioles come right out of the ground.   

[Kim]

Reminds me of my Kentiopsis pyriformis, but that would be an odd thing to happen upon, wouldn't it? 

[ruskinPalms]

My first thought was Ravenea as well. Has anyone ever had a majesty palm make viable seeds in cultivation in North America? They need a male and a female for sure to make viable seeds as far as I know.  

[ruskinPalms]

It does have a Chrysalidocarpus vibe too and would definitely be much more likely to be some sort of Chrysalidocarpus species or hybrid given where the siting is on the map. Rats and squirrels have done a good job of moving around C. lutescens in my yard and into the drainage ditch behind my yard. There are a lot of Chrysalidocarpus species that love it here in Florida for the most part. True Dypsis species are much less tolerant of Florida brutality. 

[Jimbean]

It's a majesty palm.  The only argument that I have seen so far against it is the unlikelihood of that being the case.   

[Looking Glass]

Interesting one.   If it’s a majesty in a spot like that, should double in size about every 6 months.   Perfect location for one.  And the numbers are with you…. Majesty Palms are very common.    If it is, it’s buried about 8-10 inches too deep in rocks and mud, hiding the stem area these have as youngsters.  

Here’s some photos for comparison….

Young Majesty, similar in size…

Young Majesty next to Heterospathe elata (a know Florida naturalizer and slower grower when young)….

Elata’s petioles come right out of the soil, like your palm.  They are an old school palm that’s rarely seen these days.  

Baby Archontophoenix….

Again, has a sort of stem.  

Young C oliviformis….

If you have access to this palm check back once or twice a year to see what it becomes.  I’d love to find out.  A Majesty should be a speed demon.

Growth habit is a bit odd, but I’d say it has to be Archontophoenix alexandrae. Silver abaxial surface to the leaflets rules out a lot, including Ravenea rivularis and my previous guess, Chambeyronia oliviformis. I’d guess if you dug around the leaf litter and soil you’d see the development of a crownshaft. 

[Jimbean]

Went back to the site to do further investigation.  

I went around the nearby neighborhood and took note of all mature palms.

I dug around the base to check for a crownshaft.

I went deeper into the woods to check for any other naturalized specimen.  

 

Mature palms (those that are setting seed) in the adjacent neighborhood are:

Ptychosperma elegans

Adonidia merrillii

Bismarckia nobilis

Livistona chinensis

Roystonea regia

Dypsis lutescens

Sabal palmetto

Serenoa repens

Syagrus romanzoffiana

Cocos nucifera

Wodyetia bifurcata

Phoenix roebelenii

Archontophoenix alexandrae

Dypsis decaryi

Hyophorbe verschaffeltii

Carpentaria acuminata

[Jimbean]

I found a naturalized Phoenix roebelenii, among other usual suspects.  

[Jimbean]

It just occurred to me that this is growing in the flood zone of the creek, and that sediment is hiding the crownshaft, after the minor flooding this area experienced over the last summer. This is a Archontophoenix alexandrae, along with others of this species as a result of nearby specimens from the adjacent neighborhood.

If anyone disagrees, please feel free
