Scanning electron micrograph of an early floral developmental stage of the
outcrossing subspecies of Clarkia xantania(Onagraceae). Sepals,
which are covered by trichomes, have been partially removed and floral
organs have been falsely colored: style and stigma, yellow; large anthers,
blue; small anthers, purple; petals, red. See Runions and Geber: Evolution
of the self-pollinating flower in Clarkia xantania(Onograceae).
