Western Wallflower (Erysimum capitatum ssp. capitatum)

Photographing wildflowers has many pleasures, not the least of them being what relaxed, uninhibited subjects flowers make. Just try getting this close to a badger and see what happens.

This shot shows four pollen-covered stamens surrounding a single green pistil. There's a highly technical discussion of these terms here.
