Melanthiaceae

Melanthiaceae is a family of flowering perennial herbs in the Northern Hemisphere. The family has been recognized by relatively few taxonomists, and the circumscription has varied. Early authors considered these plants to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like the flowers of the Lily Family., while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize such a family and places it in the order Liliales, in the clade monocots. As circumscribed by APG II it includes 11-16 genera of the plants that sometimes have been treated as family .
