A NEW SPECIES OF HYDNOCARPUS 



By C. DeCandolle 



(Geneva, Switzerland) 



In November, 1914, Mr. T. Alcala of Daraga, Albay Province, 

 Luzon, submitted to the Bureau of Agriculture in Manila, some 

 rather large detached fruits, accompanied by an inquiry as to 

 whether or not they were edible. The fruits, which resembled 

 nothing that had previously been received in the herbarium of 

 the Bureau of Science, were identified by me as belonging to 

 the Flacourtiaceae. A request was then sent to Mr. Alcala, that 

 an attempt be made to secure flowering material of the plant. 

 To this request Mr. Alcala courteously complied, and in February, 

 1915, collected flowering specimens of the plant which he trans- 

 mitted to Manila. This material reached Manila after my de- 

 parture for the United States, and in view of the possible special 

 interest of the plant, a portion of it was transmitted to Dr. 

 C. DeCandolle in Geneva for identification. In view of the fact 

 that chaulmoogra oil, which is produced by Asiatic represen- 

 tatives of the closely allied genus Taraktogenos, and perhaps 

 by representatives of the genus Hydnocarpus, it was thought that 

 this Philippine form, having numerous large seeds, might prove 

 to be of some value, and that its oil might possibly have the same 

 curative value in the treatment of leprosy as is found to be the 

 case with the true chaulmoogra oil. — E. D. M.
