Complete versus Incomplete Flowers
Captions available
The idea
A complete flower carries all four whorls, per Bio 2197; an incomplete flower lacks one.
In practice
A lily is complete, bearing all four whorls in one flower; a willow's flower is incomplete, lacking petals and sepals entirely.
Where people slip
"Perfect" describes a flower with androecium and gynoecium — narrower than "complete."
