after three years, do you still think this is groundsmoke? (I'm thinking Epilobium)

The photos aren't great, but yes, I still think Gayophytum. The Epilobiums seem to always have notched--or even bifurcated--petals. The closest one would probably be E. brachycarpum, and this is not that (to my eye, anyway).

Did you have another candidate species in mind?

No, it was just a feeling from the overall appearance. Since so much time had passed, I just wanted to see if you still thought it was groundsmoke before I started looking up species.

I'm really weak at reading these keys, but it looks like Epilobium and Gayophytum part ways in #3, where Epilobium goes with the group with erect sepals and Gayophytum goes with the group with reflexed sepals. http://ucjeps.berkeley.edu/cgi-bin/get_IJM.pl?key=208 I see reflexed sepals in your second photo.

Yeah...no. When they start talking about papillae on the stamens of a flower this size before they even get to Genus, I get a little glassy-eyed: I can barely see the blossom, much less the stamens! I've kind of lost hope for getting to species on Gayophytum.

But I would concur with your read on the division.
