Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae. They are native to Central America and western North America, from British Columbia to Guatemala. 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. Recent treatments have divided Brodiaeoideae (or Themidaceae) into 12 genera. The monophyly of several of the genera remains in doubt. As currently circumscribed, the largest genera are Triteleia, with 15 species, and Brodiaea, with 14. Nine of the 12 genera are known in cultivation, but only species of Brodiaea and Triteleia are commonly grown.
