12 genera (see text) Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales.

In molecular phylogenetic analyses, Brodiaeoideae is strongly supported as monophyletic.

Inflorescence an umbel, or rarely a single flower, at the apex of a solitary scape.

For most of the 19th and 20th centuries, when the group was recognized at all, it was usually at tribal rank and usually called Brodiaeeae.

[9] Toward the end of the 20th century, it became increasingly evident that the heterogeneous Liliaceae recognized by most authors was several times polyphyletic and that Brodiaea and its relatives were closer to Asparagus than to Allium or Amaryllis.

[14] When the Angiosperm Phylogeny Group published the APG II system in 2003, Themidaceae was treated as an optional circumscription for those who thought that Asparagaceae sensu lato should be divided into smaller segregate families.

[1] According to the Angiosperm Phylogeny Website as of May 2011[update], the genera included in the subfamily are:
