When the author saw the first sample collected by late Mr. Tomi- 

 jiro Uchiyama its inflorescence had been eaten nearly by insects. So 

 he thought that the collector's explanations on the plant is surer than 

 the examination on such worm-eaten flowers. What the collector told 

 him was as follows. 



"A tree becoming 15 feet high, branching. Flowers are just like 

 Cacalia crepidifolia and white." 



Believing him the author made his descriptions of the plant ; thus 

 the plant unfortunately was put under Cacalia. The Plant grows in 

 the shady forest and is exceedingly rare. The author could find only 

 five specimens in the forest of the m't Chuozan or the central hill. 

 Flowers are said to appear late in autumn.
