Like Mark McDonough, I was wondering about the Themidaceae. Is it to 
include some South American genera too? There is (or was when my reference 
book was written) at least one actual Brodiaea in Chile (B. porrifolia), 
along with Leucocoryne, Fortunatia (which has a raceme, not an umbel), and 
some others that may be closer to Allium, such as Tristagma. And where does 
Nothoscordum end up (other than in the garden where we wish it were not)?
