{H. Yamamoto ! 1907, 1908 and 1911) ; Prov. Hyuga in 

 Kiusiu (5. Bandb ! 1909). 



'This parasite was found at first by Mr. Yasusada Tashiro in 

 the mountains of Tashiro-go in the province of Osumi in the 

 southern part of Kiusiu, and the coloured figures by him appeared 

 in his manuscript '' jg^ESlSfflSIl " (The Figures of Citri in 

 Kagoshima Prefecture) as ''an undetermined parasitic plant." 



The flowers of this parasite are probably pollinated by some 

 species of Fly. 



My thanks are due to the kindness of Messrs H. Yamamoto 

 and S. Bando, who sent me the valuable materials collected by 

 them. I also wash to express my gratitude to Prof. S. Kusano, 

 who kindly gave me the specimens of this curious parasite, which 

 he got from the collector H. Yamamoto's hand in the province 

 of Tosa and brought back to Tokyo in 1907 for determination.
