There is a Sabal in my neighborhood that has had the town palmies talking for a couple decades. It could very well be a Sabal palmetto with some type of variance in it's expression. That would be my guess. It could also be a species other than palmetto. I have included shots of the canopy in this post and will put close ups of the leaves on the next. In my opinion it is quite disparate of the normal palmetto form in its ribbon like divisions as opposed to the typical costapalmate form. The inflorescence is appearently sterile. I am going to revisit this palm in three months to see if the newest flower set is again sterile. The sterility may suggest a hybrid. As much as I love Sabals I am not sure if the same rules apply to sabal hybrids with regard to self sterility. Take a look and if you have an opinion then by all means..
