Lilianae (also known as Liliiflorae) is a botanical name, for a superorder (that is, a rank higher than that of order) of flowering plants. Such a superorder of necessity includes the type family Liliaceae (and usually the type order Liliales). Terminations at the rank of superorder are not standardized by the International Code of Nomenclature for algae, fungi, and plants (ICN), although the suffix -anae has been proposed.

Lilianae, introduced in 1966 as a superorder progressively replaced the older term, Liliiflorae, introduced in 1825 as an order.

Liliiflorae was a term introduced by Carl Adolph Agardh in 1825 as a higher order to include the Liliaceae (which he called Coronariae) and related families. Argadh, together with De Candolle developed the concept of ordered botanical ranks, in this case grouping together De Jussieu's (1789) recently defined collections of genera (families) into higher order groupings (orders). However, at the time what are now known as families were referred to by the term ordo, and in Argadh's nomenclature these were grouped into classes.

While De Jussieu placed the type family or ordo, Lilia together with seven other ordines in the Classis, Stamina Perigyna of the Monocotyledones (monocots), de Candolle, who called the type family Liliacées in French, considered them to belong within those vascular plants (Vasculares) whose vascular bundles were thought to arise from within (Endogènes, endogenous), a term he preferred to Monocotylédonés. Jussieu's Monocotyledones thus became the Phanérogames, meaning "visible seed", hence Endogenæ phanerogamæ. De Candolle's Phanérogames thus defined included 22 familles. By contrast, Argadh's more specific grouping of classis Liliiflorae contained only ten families, and positioned the Liliiflorae within a larger grouping, the Cryptocotyledoneae (i.e. Endogènes).
