Jack-in-the-pulpit, Arisaema triphyllum (L.) Schott., may bear monoecious or dioecious flowering stalks. Sex expression is not fixed, but may vary from season to season. Pistillate plants tended to be larger than staminate plants, with monoecious plants being intermediate in size, but no single morphometric measurement or combination of measurements separated these plants. Spathe and spadix colors varied independently and appear to be under genetic rather than environmental control
