The genus comprises approximately 30 species distributed across North America and Eurasia. These ephemeral perennials are characterized by their solitary, nodding, lily-like flowers and pairs of basal leaves that are often distinctly mottled with brown or purple. They emerge and bloom in early spring before the tree canopy develops, then become dormant in the summer.
