Habenaria iyoensis Ohwi (Orchidaceae), previously known only from southern Japan and Taiwan, was found in the lowland of Jeju-do. This species is distinguished from the related taxa of Korean Habenaria by 3-nerved sepals, short-cylindrical spurs, and rosette leaves. The local name Ae-gi-bang-ul-nan-cho implies a smaller plant than H. flagellifera. The morphological characters and illustrations of the species are provided with photographs at the habitat.
