I have a volunteer floweriing in the back yard. I have never grown any
members of this group so it must have come from a bird or some other
vector. Anyone know what it is? Flower is 5-6" across, largest leaf is
9" across. Flower is actually sulfur yellow but I can't seem to get the
pic color right. It hd one flower close already but it just dropped off
instead of forming any sort of fruit.

A view of the embryonic fruit behind a female flower would be good. Often
the female flowers growing start after the male flowers.
