This genus [Dichelostemma] has been 
considered to be a part of many different families including Alliaceae. In 
The Jepson Manual (1993) it was classified in Liliaceae. Recent work is now 
placing it in a new family, Themidaceae, which includes other California 
genera (Androstephium, Bloomeria, Brodiaea, Muilla, and Triteleia.)

Can somebody cite a definitive technical paper that defines the boundaries of 
Themidaceae.  I'm aware of the existance of this new family, particularly in 
regard to pulling Triteleia and Brodiaea out of Alliaceae, but this is the 
first I've heard that Muilla is also swallowed up by Themidaceae.  What are the 
defining characteristics that separate the Themidaceae from Alliaceae? I need 
to be convinced, because the evidence I've evaluated thus far seems less than 
convincing (regarding the very existance of Themidaceae).  Regarding Muilla, 
this is an anagram of Allium (of which there are several) to describe a closely 
allied genus (Muilla is Allium backwards).  So it's ironic indeed, that such 
an ally is moved out of Alliaceae, don't you think?
