At first glance, I thought that this guy was related to the sand ginseng in front of me, and the appearance of the contraction of the corolla mouth was like a very good sand ginseng, but the structure of the stamens and pistils was far from the same.

Fly grass Silene gallica
Caryophyllaceae
Silene is a genus of flygrass
