I met it on a wild beach of a small island in a rainforest area around Mirim-Paraty..
It is a pity I didn't take pictures of the leaves,( there was so much to see ) but one can see a glimpse of them on some of the pictures..

It could be a type of 'Pink Trumpet Tree' Myriam. Tabebuia sp.

Family Bignoniaceae, I will have to go back to find the Brazilian sites on other threads as I lost them in the favourites that didn't transfer!

Tabebuia heterophylla is very similar but I have to check the list.

Tabebuia rosea is in Brazil

The flowers look broader but I don't yet know if there's another pink one in Brazil..

Tabebuia pilosa could be pink! Flower shape is closer..

There's a couple I can't find pics of but it does look like Tabebuia, could be something else though!

Thanks Janet, the flower shape does look like Tabebuia, but all the flowers I have seen on the links look ruffled on the rims..I have the impression that the leaves on mine looked more thick and sturdy than on tabebuia pilosa
