Slender Beardtongue

Slender Beardtongue Penstemon gracilis is in bloom at the edge of the woods. Like other plants in the Penstemon family, each bloom has a fuzzy flap in the center; it is an infertile stamen among the four fertile stamens. The infertile stamen or "staminode" looks like a yellow or orange hairy "tongue", inspiring the name: beard tongue.
