Dypsis sp suckering from the trunk
Entire leaf form of the same species
The inflorescence is branched to the first order but can also be spicate.
Showing spicate inflorescence also note that the leaf arrangement is regularly pinnate it can also be irregular as well, this same plant has now changed it's leaf arrangement after 10 years.!!

As with many of these species the entire leaf form is quite rare and it will divide a little with age, i'm still yet to work out what this species could be, at first i thought i was looking at two species but now i think i'm looking at one, anyway this species grows very well in the subtropics even growing in the garden un-maintained.

We have quite a few of these at good sizes available now..!
