Corn Sandspurry

Corm sandspurry (Spergula arvensis)

Corm sandspurry (Spergula arvensis) is a plant that at first sight can be confused with Gilia millefoliata. They are both tiny inconspicuous plants and the leaves look somewhat similar. However, if you look close, you'll see that the flower structure of spergula is quite different: it has a big pistil in the middle while gilia has none.
