A research team from the National Institute for Environmental Studies, Chuo University, and Niigata University confirmed that the aquatic plant "Mujinamo" grows naturally in Ishikawa Prefecture. This is the first new case in the wild in 73 years, and the researchers say it "indicates the possibility of endangered plants reappearing due to environmental changes" It is a carnivorous plant that preys on plankton and was discovered in Tokyo in 1890 by Tomitaro Makino, a "pioneer" of plant taxonomy in Japan.
