Abstract

A new species of Oxygyne (Thismiaceae), O. yamashitae, a saprophytic/mycoheterotrophic species from Yaku Island, Kagoshima Prefecture, Japan, is described and illustrated. The combination of characters such as three stamens attached to the perianth and the presence of lamellae at the mouth of the perianth tube indicate that it belongs to the genus Oxygyne. It is clearly distinct from other known species of Oxygyne in having an elliptic hole in the corona, in which stamens are inflexed, and in having three dichotomous appendages below the stigma. The discovery of O. yamashitae demonstrates that the lowland evergreen forest in Yaku Island is a hotspot of endemic plants and worthy to be conserved.
