See text Melanthiaceae, also called the bunchflower family,[2][3] is a family of flowering herbaceous perennial plants native to the Northern Hemisphere.

[4] Along with many other lilioid monocots, early authors considered members of this family 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 those of lilies,[4] while some more recent taxonomists have placed them in a family Trilliaceae.

Familiar members of the family include the genera Paris and Trillium.

[6] Generic assignments within the tribe Melanthieae in particular have been changed radically as a result of molecular phylogenetic studies in the 21st century.

[4] Some taxonomists have combined the three genera of Heloniadae into one genus (Helonias).
