Brodiaea has been transferred from Alliaceae to Themidaceae. Plant Systematics: a Phylogenic Approach states that Brodiaea is usually classified under Alliaceae. However, "recent cladistic analyses have indicated that the genera of Themidaceae are more closely related to Hyanthicaceae than to typical Alliaceae"(2002). This change is also supported by the inclusion of Brodiaea into Themidaceae on the Angiosperm Phylogeny website: http://www.mobot.org/MOBOT/research/APweb/
While others grumble about change, appear not to trust it, I think all this new taxonomic information being generated by modern methodology is interesting and exciting.
