Caribbean flower

No idea what this flower is but maybe someone can tell me.

Today has been a lazy pool day so far. I did a few images around the pools of flowers etc. more can be seen here and here.

I chose this because of the veins that can be seen in the in focus part of the image.

It's only mid afternoon so am back off to the sun for more reading and rum punch!
Will catch up with comments a little later - hopefully spelling will not have taken too much of a hit.... :-)
