Lilieae
# Lilieae

The Lilieae are a monophyletic tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the lily family (Liliaceae).

## Taxonomy

The term has varied over the years but in modern classification constitutes either a broad circumscription (Lilieae sensu lato, s.l.) with eight genera, placed in the subfamily Lilioideae, or narrower circumscription with six genera (Lilieae sensu stricto, s.s.), excluding Tulipa (which now includes Amana) and Erythronium which are treated as a separate tribe, Tulipeae. Within Lilieae s.s., Gagea now includes Lloydia, and Lilium includes Nomocharis, reducing the number of genera to four, with about 260–300 species.

Distribution of Lilieae genera :

| Genera | Sensu stricto | Sensu lato |
| - | - | - |
| Cardiocrinum | Lilieae | Lilieae |
| Notholirion | Lilieae | Lilieae |
| Nomocharis | Lilieae | Lilieae |
| Fritillaria | Lilieae | Lilieae |
| Lilium | Lilieae | Lilieae |
| Gagea | Lilieae | Lilieae |
| Lloydia | Lilieae | Lilieae |
| Amana | Tulipeae | Lilieae |
| Tulipa | Tulipeae | Lilieae |
| Erythronium | Tulipeae | Lilieae |

## Distribution and habitat

Lilieae s.s. are distributed in temperate Northern Hemisphere areas, with the main centre of diversity in the Qinghai–Tibet Plateau, where about 100 species may be found. Other areas include East Asia, Central and West Asia, the Mediterranean Basin and North America.
