Abstract / Introduction / Summary:

An endangered species of orchid Herminium lanceum (Thunb. ex Sw.) Vuijk was reported for the first time on Kuchinoshima Island, Tokara Islands, Kagoshima Prefecture, Japan, based on photographic evidence. Previously, in the Tokara Islands, this species was known only from the islands of Nakanoshima, Gajajima, Suwanosejima, Tairajima, and Akusekijima. The individuals were found in narrow grass strips between thickets of Pleioblastus linearis and a hiking trail. Maintenance of this environment may be important for the survival of this population.
