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.[1][2]
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.[2]
