This plant is growing in my fields about 4-8 inches high. It blooms a single flower and grows a little taller to bloom another, and so on. There appear to only be 3 true petals. One large petal wraps around the top 180 degrees of the flower and two smaller ones (each take up a bottom 90 degree corner). The stem is somewhat hairy and prickly. The leaf veins are branched and leaves are deeply serrated. The flower is about 3/8 inch wide and solid yellow, though as they die and dry they gain a little reddish to them.
