Caption:
Magnified 202X, this scanning electron microscopic (SEM) image revealed some of the floral ultrastructure of an unidentified specie of spiderwort flower, Tradescantia sp. In the background on the left, the centrally located stigma is visible. It is unto the stigma that the pollen must land, in order to pollinate this flower. The spiderwort's sap is very viscous, and when touched between the fingertips, the sap will stretch, much like the strands of a spider's silky web. The three petals of this particular specie of Tradescantia were colored blue-violet, accented by six bright yellow, pollen producing anthers, which sat atop the ends of their complementary blue-violet filaments. This micrograph was produced in the month of March, for the flowers bloom in springtime, and were founds growing on the grounds of the Centers for Disease Control and Prevention (CDC) headquarters in Atlanta, Georgia.
