Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae.[1] They are native to Central America and western North America, from British Columbia to Guatemala.[2] The name of the subfamily is based on the type genus Brodiaea.

In molecular phylogenetic analyses, Brodiaeoideae is strongly supported as monophyletic. It is probably sister to Scilloideae.[3] Recent treatments have divided Brodiaeoideae (or Themidaceae) into 12 genera.[4] The monophyly of several of the genera remains in doubt.[5] As currently circumscribed, the largest genera are Triteleia, with 15 species, and Brodiaea, with 14.[6] Nine of the 12 genera are known in cultivation, but only species of Brodiaea and Triteleia are commonly grown.[7]
