Gastrodia kuroshimensis (Orchidaceae: Epidendroideae: Gastrodieae), a new mycoheterotrophic and complete cleistogamous plant from Japan

Abstract

A new species, Gastrodia kuroshimensis (Orchidaceae: Epidendroideae: Gastrodieae), from Kuroshima Island, Kagoshima Prefecture, Japan, is described and illustrated. The outlined floral morphology indicates a close affinity to G. fontinalis, but it is easily distinguished by several characteristics, such as the cleistogamous floral condition, smaller perianth tube size and the anther cap joined with the column.
