Which Geonoma sp is this?

[Alberto]

Last week I went to a palm nursery in the city of Corupá, Santa Catarina state, south Brazil. It is located at 400 m altitude between the mountains of the Serra do Mar.  There they can grow a big range of palms, from temperate and even some amazonian species. The gardener showed me a palm he told was a Geonoma sp. It saw some light frosts that burned some banana leaves on the mountais but the palms where not touched. They also transplant easily he told me. He showed me two of this  palms that were removed from the soil with a rootball , one in a pot and the other laying down on a concrete floor. The last one was surviving for two years and  even forming a bend on the trunk that was growing. Can somebody identify it? Could it be a form of Geonoma undata? Thanks.

Could be undata.  I have seen them with droopy leaves like that. Leaf scars/trunk look a little different but it's a young plant.

I’d guess undata but it’s the only Geonoma I know quite well.

If you know it quite well.... I can say G. undata is a variable species when I see pictutes of it in different habitats.

What else could it be....?  I can't think of any larger cool tolerant Geononmas that come close.

You are right. I also don't know what else it could be.
