What is this yellow flower?

Question

This yellow flower was growing in my yard in St Petersburg, Florida. It did not survive my xeriscaping.

I've never seen the species before, but a stab in the dark: Winter Cassia? (Senna bicapsularis aka Cassia bicapsularis). The curved anthers in that group are pretty distinctive, but I'm not at all certain that it is bicapsularis, though.

That appears to be the one. The leaves are what did it for me. The flower is dead on too. Thanks. – Gardening Directions Jul 11 '11 at 16:16

It looks like a buttercup flower. Hard to tell without a picture of the rest of the plant though. Was the plant tall and skinny, with leaves such as the ones on this link?

The buttercups that I know of, also have a distinctive seed head, so that is probably something else to look for. – winwaed Jun 29 '11 at 17:30
