Time for more unknown flowers

In addition to wildlife viewing (I’ve got a number of baby buffalo photos), the Lamar Valley excursion also provided some wildflowers.

I’m guessing that these are some kind of Stickseed, though I could be wrong. At first I thought they might be Forget-me-nots. However, these flowers are more on a long stem than ground cover.

There were some white flowers that looked very similar. And they were in the same cluster of plants.

I did crop out a forward facing shot, however, from one of larger photos.

So this might be Stickseed or it might be Mystery Flower(s) #4. I’d appreciate confirmation and correction by someone.
