This image was taken in Puebla, Mexico, using my Coolpix 4500 (I love the macro mode on this camera, and haven't been able to part with it). I'm not sure what type of flower it is...
This is a truly great (10++) shot of: Lantana camara 'Ham and Eggs' (Ham and Eggs Hardy Lantana). It grows like a weed in Texas, too. Our garden is full of it. There's an all-yellow variety, if you like your "eggs" with no "ham."
