Micro Blossom: 146th Flower of Spring & Summer! (1 more pic below)

I found a bunch of flower species in the dried up area of our seasonal pond. This tiny flower was so small that I didn't realize it was a blossom until I leaned down to look closely! Its face is only 1/16" in diameter, and it forms a tube that is about 1/3" deep. Unfortunately, this is another flower I couldn't identify but if I discover what it is, I'll add correct information. It looks a little bit like a Penstemon but I just don't know!
