Ptychosperma fr Australia ID Lg Leaves/Lg Seeds

[PalmatierMeg]

I have nearly a dozen pots I germinated from seeds sent to me by a Pter in Australia back in 2019 when I could still obtain seeds from overseas. He did not have a name for this palm and called it, "Ptychosperma sp Large Leaves/Large Seeds." The photo showed a solitary palm. The seedlings sat outdoors in the jungle in a crate set atop the old Washy stump for the past year, had no issues with being unprotected all winter and look immaculate. Most of my offspring from these seeds are in 2g-3g, going pinnate or about to. Could someone from Australia or elsewhere tell what species this palm might be? Is it native to Australia or elsewhere? Thanks

I agree that it is the Ptychosperma genus, it will be difficult to identify the species at its young age, although from what I see on its leaves it resembles the Ptychosperma elegans species, originally from Queensland, northeast of Australia.
 I share photos of some that I have taken. I hope it helps.

Any chance they are ptychosperma salmoense they have a pretty fat leaf. As stated hard to I'd at a young age  but looks similar to mine when I acquired it.

Did the seed look like a Ptychosperma. Ptychosperma seed is quite distinctive. 

Im not saying it is but just looking at your palm and thinking out loud I see Veitchia in it.

I can't remember after all this time but the petioles appear to have a speckled scurf on them.
