There are 3 to 7 oval or lance-shaped leaves arranged alternately on the stem, each up to long by wide. The herbage is hairy and sticky.〔(''Cypripedium passerinum''. ) The Nature Conservancy. Retrieved 11-14-2011.〕 The inflorescence at the top of the stem contains one or two flowers. The flower has a dorsal sepal covering the petals and two lateral sepals. There are three petals: two flat white petals on either side and one central petal modified into a white or pink-tinged pouch with purplish spotting at the lip and inside, which is said to resemble a sparrow's egg.〔 The fruit is a capsule. The plant may reproduce by seed but it more often reproduces vegetatively by sending up more stems from the rhizome.〔〔(''Cypripedium passerinum''. ) Flora of North America. Retrieved 11-14-2011.〕
