Trilliaceae Chevallier. Trillium Family.

Key to Trilliaceae

A family of ca. 6 genera and about 80 species, perennial herbs, of temperate Northern Hemisphere. The Trilliaceae is clearly monophyletic and strongly characterized morphologically, scarcely resembling its sibling groups (sister to Xerophyllaceae, divergence time ca. 60 million years ago); its recognition as a family seems well-warranted.
