An interesting addition to our knowledge of the relationship of the Philippine 

 flora to that of the Asiatic continent. The above specimen agrees very closely 

 with material of this species supplied me by the director of the Botanic Garden, 

 Hongkong, with Koriuosan specimens received from the Imperial University, Tokyo: 

 ami with sterile specimens in Herb. Bureau of Science from a cultivated plant 

 in the Botanical Garden at Buitenzorg, Java. The Philippine plant is, however, 

 a scandent shrub, while in all the references to Acanthopanax aculeatum Seem., 

 and synonyms of that species which 1 have been able to consult, the species is 

 described as a shrub or small tree. However. I can not. from the descriptions 

 and material available, find any other characters by which the Philippine plant 

 can be distinguished, and have accordingly referred it to the above species, which 

 extends from Japan and Formosa to China and Eastern India.
