This plant is Chimaphila maculata, referred to as Spotted Prince's-pine by my trusty (if somewhat technical) plant manual*, but labeled Striped Pipsissewa by many other books. This subshrub has waxy, blue-green leaves, with whitened veins and toothed margins. Drooping summer flowers later ripen and stand erect as brown capsules (see above). While the leaves of Noble Prince's Pine look different from those of this species, the similarity of their flower and subsequent fruit structures suggest their close relationship.
