Tanana River Curiosities

During my walks by the Tanana River, I'm growing accustomed now to seeing an abundance of a dozen or so familiar wild flowers. However, I came across one small patch which I wasn't familiar with:

I have also a few photos from last week, which I finally got uploaded. Here is some interesting Purple Clover:
