Photolady - Might have you some info. Happened to remember this and did some poking around, sometime around 4AM... take a look at Tick Trefoil.
Tick Trefoil
Quite similar, maybe not exactly the same but close. A couple of varieties around here, one pictured below. It's the variety of plants that leave the little triangular seed pods all over your clothes that are a nuisance to get off.
This is the one I mentioned a few days ago, knew I had this picture but never spotted it.

This shot also shows the leaves, typical of the Legumes. Lupines are also closely related, these two include all the Clovers, Wisteria, Kudzu, Trefoils, and Locoweed and a couple others I think.
Here are a couple more I finally uploaded, been putting it off since I Had to clean out some room on the Flickr account.
Turnsole. I'm sure I've posted this one before, but never have gotten the color to come out right. The 1/4 inch flowers are slightly more blue tinted than this picture.

Unidentified, very close to an Orchid or Orchis about 20 feet from the Red River in Shreveport a couple of weeks ago.

One of the few good shots I've gotten of this one, for some reason I always have gotten slightly off focus. It's barely over 1/8 inch wide, and grows everywhere around here, up to about 6 feet tall.

All of these were shot with the Lentar 135mm and Vivitar extension tubes.
I guess that's it for now...
Oh yeah I missed it, but 2 days ago this thread was 1 year old. Started July 26, 2010. I'm amazed it lasted this long and got so many amazing photographs.
Thanks a bunch to all who have participated, it's great to see all the very small flowers from all over the place.
