Some Wildlfowers

I don't know much about wildflowers. Almost nothing. But I often take photographs of them when I'm hiking. Here are a few I saw on my way to see the big cottonwood tree in Boone's Cave Park. I can't ID any of them, so if you know, post here.

Very small. These blossoms were on a stalk about a foot high.

These delicate blossoms were on a plant growing out of a spray of moss.

This one was pretty much alone in the sun beside the trail.

This was another very tiny flower that grew in bunches close to the ground.
