The Liliaceae or lily family was formerly considered to contain many genera that have now been moved into families of their own, such as the Alliaceae, Agavaceae, Amaryllidaceae, Hyacinthaceae, Asparagaceae and others.  More recent circumscriptions have limited the family to from 16 to 60 genera and about 650 species. This is very different from the 280 genera and 4000 species that it was once said to include. Lilies are monocotyledons with linear, mostly parallel-veined leaves and flower parts in threes. The family is mainly distributed in the northern temperate zones with a few genera reaching the subtropics, and includes some of the oldest known ornamentals of the western world. Some of the familiar genera are Lilium (from which the family takes its name), Tulipa, Crinum, Fritillaria, Chlorophytum and Zygadenus. Fruits are typically loculicidal capsules, but in some genera like Clintonia is a berry.
