Butia sp dwarf ( New specie ? )

[caixeta]

I found a dwarf Butia in Ipameri - Goiás on rock soils , I believe it is a new specie , because there are no Butia dwarves in Goiás identified . It is a very delicate palm , with great potential for landscaping . Give your opinions.

I do not think these are Butia. You can see from that last one that the two sides of the leaf do not form a strong V, but one that is more open or flatter. Also I see some loose clustering of the leaflets, which is something you do not see in Butia, but is common in Syagrus. My guess is that this is Syagrus graminifolia ssp. glazioviana, which is a small greenish form of that species (not blue like the typical  ssp. graminifolia).

Look at the spathes or peduncular bracts closely to see if it is perfectly smooth or has fine longitudinal grooves in the bract?

The irregular arrangement of leaflets caught my eye too and I am glad Larry uttered his doubts.

I found a single fruit and it was purple , see the seed . I'm almost sure it's Butia.

The leaves are well arched as em Butias ,but are simillar to Syagrus graminifolia blue . could it be Syagrus graminifolia green ?

More leaves in details .

Very interesting dwarf palm,Caixeta. I also doubt it is a Butia because of the leaflets not being regularly atached, but more like Syagrus species are. I´m interested to know which species it is.
