[Botany • 2016] Sciaphila yakushimensis • A New Mycoheterotrophic Plant (Triuridaceae) from Yakushima Island, Japan


Sciaphila yakushimensis
Suetsugu, Tsukaya & H. Ohashi 



A new species of Sciaphila (Triuridaceae), Sciaphila yakushimensis Suetsugu, Tsukaya & H. Ohashi, is described and illustrated from Yakushima Island, Kagoshima Pref., Japan. The new species is similar to S. nana, but it is clearly distinguishable by the blackish purple aerial parts, the clavate style with dense papillae, and the filaments not longer than the anthers. A key to the Japanese Sciaphila based on total flower characteristics and another based primarily on stylar characteristics are provided for convenience of easy identification of these rare mycoheterotrophic plants.

Key words: Distribution, Japan, mycoheterotrophic plants, new species, Sciaphila, Triuridaceae, Yakushima Island.
