(or sensu Tamura) to include only the tribes Tulipeae and Lilieae. However other authorities including the Angiosperm Phylogeny Website (APWeb) define Lilioideae s.l. to also include the Medeoleae (while subsuming the Tulipae into Lilieae). In the s.s. usage,

Chromosome number may be 7 (Medeoleae), 9, or 11–14, with a highly variable length (2.2 - 27 μm). The term was introduced by Amos Eaton in his Botanical Dictionary in 1836. Engler and Prantl included it as one of the eleven subfamilies of Liliaceae. In 1927, Buxbaum 's treatment of
