Lady's-Slipper, Pink/ Moccasin-Flower
 

Cypripedum acaule
A small 6-15" plant with 2 elliptical, smooth-edged basal leaves. The leafless flower stalk is curved at the tip so that the solitary flower is nodding. There is a large, inflated, pink "lip" petal with darker veins and a fissure running down the center. The 2 upper "side" petals are spreading, narrow and greenish-purple-brown. The 3 sepals are very like the side petals, one in front and 2 fused behind. Blooms April to July in acid woods, often in humus under hemlock trees. Rare.
