藜芦科科

本科植物为多年生草本；根茎短而厚；茎单生，直立；叶对生或3至多枚轮生于茎顶；花两性，辐射对称；果实为浆果或肉质蒴果。

以前许多种分类法将本科分入百合科或单独分为许多科，如延龄草科、白丝草科等，1998年根据基因亲缘关系分类的APG 分类法认为这些属应该归为一科，纳入百合目。

Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. 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, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009 (unchanged from the 2003 APG II system and the 1998 APG system), places the family in the order Liliales, in the clade monocots. Circumscribed in this way, the family includes up to 17 genera.

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

Genera and species

As of August 2013, the World Checklist of Selected Plant Families accepted 17 genera in the family. They have been divided into five tribes. It has a total of c. 173 known species. Generic assignments within the tribe Melanthieae in particular have been changed radically as a result of molecular phylogenetic studies in the 21st century. Some taxonomists have combined the three genera of Heloniadae into one genus (Helonias).
