Tree flower

Hi,
Do you know a flower called "iritrina cristalina"? I think it grows on trees in spain. I am not sure about the spelling? Someone told me about it and I am trying to retrieve that flower.
Thanks in advance!

Francesco, welcome to the forum I hope you will like it here.

It gets a bit difficult to search for this flower if the spelling isn't accurate since with a non-accurate spelling the pronunciation can differ...
How do you pronounce this?

Erytrina Crista-galli may be?

I've never seen or heard of this tree before. http://www.cas.vanderbilt.edu/bioimages/species/ ercr6.htm http://en.wikipedia.org/wiki/ National_Flower_of_Argentina

I have heard of the coral tree which is the tree I believe that LA wants to replace with something else that has the environmental folks in an uproar. Apparently, from what I understand, these trees are favorites for the parrots who use them for shelter and food.

Is this the tree you are talking about?

Yes, thank you Julie.
