抄録

This is the first report of Taeniophyllum complanatum from Yakushima Island, Amami-Oshima Island, and Okinawa Island, Ryukyu Islands, Japan. The species is rare and was previously considered to be endemic to Taiwan. It is distinguishable from T. aphyllum by its strongly flattened roots, minutely papillate inflorescences and the shape of the fully developed fruit.
