Published in the New Plantsman. A slow growing tree found on steep rocky mountainsides of the temperate rain forests of Southern Central Japan. It is the only species of its own genus the Sciadoptyaceae.
Now only found in Japan, it is the sole survivor of a very ancient genus of tree widespread in the northern temperate zones during the Tertiary Age, dense beds of fossil leaves occur in the Miocene coasts of the former East Germany. Today most of the wild forests have been felled for its very fine timber.
