The order Asparagales as currently [[circumscription (taxonomy)|circumscribed]] has only recently been recognized in classification systems, through the advent of [[phylogenetics]]. The 1990s saw considerable progress in plant phylogeny and phylogenetic theory, enabling a phylogenetic tree to be constructed for all of the flowering plants. The establishment of major new clades necessitated a departure from the older but widely used classifications such as Cronquist and Thorne based largely on morphology rather than genetic data. This complicated the discussion about plant evolution and necessitated a major restructuring.{{sfn|ps=none|Angiosperm Phylogeny Group II|2003}} ''rbc''L gene sequencing and cladistic analysis of monocots had redefined the [[Liliales]] in 1995.{{sfn|Chase et al.| 1995a}}<ref>{{Harvtxt|Rudall|Cribb|Cutler|Humphries|1995}}.</ref> from four morphological orders ''sensu'' [[Rolf Dahlgren|Dahlgren]]. The largest clade representing the Liliaceae, all previously included in Liliales, but including both the Calochortaceae and Liliaceae ''sensu'' Tamura. This redefined family, that became referred to as core Liliales, but corresponded to the emerging circumscription of the [[Angiosperm Phylogeny Group]] (1998).{{sfn|ps=none|Patterson|Givnish|2002}}
