No-tag palm planted in early 2018 that I thought might be a New Caledonia species, but clearly is not. Bo and I think it looks related to his much beefier Hydriastele cylindrocarpa, thus I tend to think Hydriastele— but which? I have some ideas, but would like to know what others can see in this palm.  A bit difficult to see in the photos, but the terminal leaflets are wider than the others, and all have notched tips.

Aloha Kim, I don’t think it’s a Hydriastele, no crown shaft and the pinnae look different. It reminds me of something in the memory bank, but there seems to be a short circuit at the moment.

Ha-Ha, senior moments seem to occur with increasing frequency for me !     

[Kim]

@realarch Might this palm resemble any you saw in Australia? 🧐

[John hovancsek]

It kinda reminds me of h. Cylindracarpa or hombronii. I am bad at spelling. 

[John hovancsek]

I take the previous post back. H. Longaspatha the pic is the one I have. ( in the back)

[Kim]

Hi John. Your palm looks a lot like mine, for sure. Are the leaflets somewhat irregularly spaced? On mine some of the leaflets are in a group of 3. 

[John hovancsek]

No but here is the one that I was thinking of but only know it is hydrastele

[John hovancsek]

Maybe h. Macrospadix. I wish I could be more helpful 

[John hovancsek]

Here is a pic of my h. Cylindrocarpa to help rule out what it’s not

[Kim]

Based on your photos, Hydriastele is a definite 'maybe.' 🙂 Perhaps once it begins flowering there will be more clues. It seems fairly fast growing -- are your Hydriastele fairly fast?  Thanks for the photos and help.

[John hovancsek]

Yes. Fast for me and I am higher than u . I am at about 1400 ft elevation

Sorry - late to the party... I think Hydriastele is a reasonable guess, esp if all the leaflets are praemorse (have that jagged, bitten-off look). Unfortunately, these things are really challenging to name (by me at least) until they are adult and flowering/fruiting. I am relatively comfortable with the New Guinea ones, though there are relatively few either side, so it should be possible to narrow it down in time. Patience needed unfortunately!

Carpentaria acuminata

Another possibility, I suppose. No idea where I would have picked one up, though.  Time will tell.

Thanks for taking a look. This palm is growing faster than everything around it, so with luck I won't have to wait too long for more clues.  Appreciate your reply, cheers.

Had a look at the fronds of some of my solitary Hydriasteles (longispatha, macrospadix, vitiense - all former Gulubias). Leaflets are broader than those shown in the pics, more closely spaced and very regularly spaced. Leaves are very arching in mature specimens. Only terminal leaflets are praemorse, others are lanceolate. Also have Hydriastele (Gulubia) costata, but that is very different with its pendant leaflets and pretty much unmistakeable. So, I can't help, sorry.

[Kim]

Thanks for taking such a close look, Mike! I appreciate the response. At least it eliminates some of the possibilities.

I would say Carpentaria

I'd say the same thing. Trunks of carpentaria look just like a foxtail. VERY fast growing species. Once trunked,my 2 both added 3 feet of wood each year in Arizona. But in Hawaii?

Carpentarias do very well here in East Hawaii Island, grow lightning-fast, and are often used for public landscaping. (I have four on the access road to my house.) But the leaves are very arching on mature specimens. Maybe they need some maturity before that happens.

Is there any Carpentarias in so cal that is known to survive?

If they can be grown in Arizona, they HAVE to survive in So Cal... ( the 2 skinny trunks between the 2 royals are carpentaria)

Very nicely grown Scott, I wish I could get my hands on one, haven't came across one for sale yet. But would like to get one someday. Thanks for the hope of growing one of these days. Trying to get my brother into palms, he lives in Gilbert. You have a nice collection in that crazy heat and cold, great work!
