First, I wouldn't bang my head against the wall trying to nail down exactly what any particular Phoenix hybrids come from as far as parentage. They hybridize so readily and there are just so many variations around. Species cross and then the hybrids cross and so on that there are some very odd looking plants out there.

That being said....and not following my own advice....the first photo below the reclinata looks like a cross with a sylvestris involved. I say this because of the yellow coloring on the leaf base in the lower photos. Maybe with a rupicola because the leafs have a soft appearance. It may not be any of this though because I think I see some little suckering plants coming from the base of the plant and both of those varieties are solitary trunked. Who knows??? I have these 14' tall plants nearby that look exactly like a rupicola but are suckering like crazy.

The issue of the new growing point coming out of the side of the trunk is interesting. If I am seeing this correctly the trunk looks as though it is shooting out a branch about 2' up from the base of the trunk. There are 2 photos of this occurance in your post. Are these shots of the same trunk or of 2 different trunks on the same multi-stemmed plant?

At any rate this looks like an aberration or abnormality. If these last 2 photos are of differnt trunks on the same plant then this aberration is carried out through the DNA of the whole plant. Very weird. If you get too close and catch whatever it has you may sprout a little twin out the side of your leg. BE CAREFUL!!!

I saw a multi headed Veitchia once where the new grow points started out like a petiole of a frond but instead of
becoming a frond they became new heads attached to the main trunk with a leaf base.

I hope all this mumbo jumbo helps.

Steve that is what I was looking for. Mumbo Jumbo is my language. Now ALL of the more mature trunks had these extra heads. So if this is in its DNA what are the chances the seeds would carry this trait. I find it very unusual!

I don't know. Phoenix palms are dioecious (need 2 palms to reproduce) so there would be input from the other parent as to offspring predisposition to branch like this. If it were a monoeciuos palm I would say that there would be a much greater chance that this trait would carry on. Just speculation though.

I find it very unusual as well. Really neat!

Hybrid Phoenix palms are quite common in So Fla. I just planted 3 Phoenix reclinata x roebellini palms I bought here in Palm City. The nursery had other hybdrids, such as reclinata x sylvestris hybirds. Prices are reasonable, I paid $40 for 7 gallon specimens.
