Dichelostemma capitatum

Robert Preston is the man who has done work on what they call the
Brodiaea complex and the main change that I've seen lately is to remove
Dichelostemma capitatum from Dichelostemma and back to an earlier name
in a genus with it as the only representative, although there are
subspecies. This species differs from the others in that genus by having
6 stamens and if you read Preston's paper has had a checkered past in
terms of naming. This species is commonly known as Blue Dicks and is
widespread in California. On the wiki we have a lot of photos from
different counties and it varies greatly in size and time of flowering. 
It looks like we get to keep the common name. Calflora hasn't changed it
yet, nor has the Flora of North America, but Jepson has. You can read
about it here:

Dipterostemon capitatus (Benth.) Rydb.
BLUE DICKS

Dipterostemon capitatus (Benth.) Rydb. subsp. capitatus

Dipterostemon capitatus subsp. lacuna-vernalis (L.W. Lenz) R.E. Preston
VERNAL POOL BLUE DICKS

Dipterostemon capitatus subsp. pauciflorus (Torr.) R.E. Preston

These kind of changes play havoc with photos on the wiki as keys often
require information not readily apparent (like size of filaments,
perianth, sometimes corms, height, etc.)

Since this change hasn't been widely adopted I guess I can put off
worrying about that for awhile.

But Jane I think there continues to be great variation in the forms of
Triteleia laxa and I'm hoping no one is going to split them up into
different species.
