Liliaceae
The
Liliaceae, or the
Lily Family, is an important family of
monocotyledons that includes a great number of ornamental flowers as well as several important agricultural crops; the
onion has traditionally been classified here, though modern research has moved it to family
Alliaceae. Plants in this family have linear leaves, mostly with parallel veins, and flower parts in threes.
The Lily family formerly included a great number of genera that are now included in other families, and some in other orders. The family
Smilacaceae was formerly included in the Liliaceae but now is segregated on several bases. Family
Melanthiaceae (
Trilliaceae) is also now segregated by most taxonomists. Many other genera formerly classified in family Liliaceae are now widely thought to belong to families in order
Asparagales.
Genus
Calochortus, which includes the Sego and Mariposa lilies, and its allied genera are separated into a separate family, Calochortaceae, in some schemes, while others maintain them as a subfamily of Liliaceae, the Calochortoideae.

The lily flower is used in
heraldry. See:
Fleur-de-lis.
Genera
\nThe list below includes genera that have historically been classified in family Liliaceae. Monocot classification has undergone considerable revision in recent years, and some newer systems, including the Angiosperm Phylogeny Group's APG 2 classification system, have assigned many of these genera to different families based on genetic relationships. The APG 2 families are listed in brackets. \n
