Anemone berlandieri Pritz.

Anemone berlandieri Pritz.. Anemone berlandieri, commonly known as tenpetal thimbleweed or tenpetal anemone, is a rhizomatous perennial flowering plant in the buttercup family Ranunculaceae. It is native to much of the Southern United States, where it flowers in the late winter and spring, between February and April. The specific epithet berlandieri honors Jean-Louis Berlandier (1803–1851), a botanist who explored Texas and Mexico in the nineteenth century.
