The Liliaceae Family
Lily Family - Monocots
The Liliaceae is now, after taxonomic changes, a medium size family. They are ecologically diverse and widely distributed in the temperate regions of North America although most species are native from Asia to China.
In North America there are 108 genera with 955 accepted taxa overall. The Plant List includes 746 accepted species names in Liliaceae.
Originally the Liliaceae was a large complex family of monocots sharing similar characteristics such as; petals and sepals looking similar (tepals), 6 stamens and a superior ovary, parallel venation and a three chambered capsule. As a result many sources and descriptions still include species which have long since been placed elsewhere through better taxonomic research and methods which have improved through the use of plant genetics and molecular biology. Examples of families containing species previously included in Liliaceae include Asparagaceae which includes Agave, Dichelostemma, Hesperaloe, Nolina and Yucca; and the Amaryllidaceae which include Allium, Nothoscordum and others.
Characteristics of the Lily Family are large showy flowers divided into 3 and 6 parts, flowers are radially symmetric (actinomorphic) petals and sepals similar in appearance and collectively called tepals which are often arranged in whorls, 6 stamen and a superior ovary and a 3 chambered capsule. Other common characteristics include alternate or whorled leaves, some leaves clustered at the base, leaves linear, simple, entire, generally parallel venation and living part of their life cycle underground as bulbs or rhizomes.
Many species in the Lily Family are cultivated as ornamental plants throughout the world for outdoor landscapes and indoor containers, especially Tulips (Tulipa) and Lilies (Lilium).
Members of this family produce nectar and pollen attracting a wide range of insects including bees, wasps and butterflies.
