Dichelostemma--TOW

Jane,
No South American Themidaceae. Strictly Southwestern and Western U.S. and
Mexican. There is no true Brodiaea in Chile. All the Chilean onions are
still onions.

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)?

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?
