Watershield (Brasenia schreberi) in bloom. I don’t believe I have ever seen watershield flowering. Have you? I really appreciate this photo from Wade Simmons, via Twitter. Watershield occurs in Oklahoma and Arkansas and surrounding region. Nuttall mentions it in a lake near the Kiamichi River down south near the Red River (pg. 181).
