HYDNOCARPUS SUBFALCATA MERRILL 



Quoting from the same bulletin as before: 



This species is found in Zambales, Pangasinan, and Cagayan, Luzon; 

 Sibuyan, Saraar, and Mindanao (Surigao). It bears a green fruit 1 to 4 

 cm in diameter containing from 2 to 8 small seeds. Its local names are 

 mala usa, binting dalaga, amitan (Ibn.), apanang (C. Bis.), dalinias 

 (Sbl.), damol (S. L. Bis.), lagtang (P. Bis.), ngeret (Tag.), pai (Pang.), 

 putian (Sbl.). 



A small supply of H. subfalcata seeds has been obtained 

 from the Provincial Treasurer of Zambales. The fruit ripens 

 in May. 



HYDNOCARPUS VENENATA GAERTNER 



The seeds of this species are similar to those of Hydnocarpus 

 wightiana (see the following- species) but are smaller, and have 

 seven veins in the cotyledon instead of five Our samples were 

 obtained from Ceylon, through the Su tendent of the Pera- 



deniya Gardens. This species is said e found also in East 

 and West Deccan, and in Burma. 



HYDNOCARPUS 



This species appears to be available in larger quantities than 

 any of the other species of the chaulmoogra group. The seed 

 is about 2 centimeters long with longitudinal grooves, and a 

 knob at the end. It is found in southwestern India and shipped 

 in commercial quantities from Ernakulam. The Ernakulam 

 Trading Co. also presses out and exports the oil. 



Our sample of this species was collected by Mr. A. D. E. 

 Elmer, in British North Borneo, near Sandakan. The seed is 

 similar to that of Hydnocarpus hutchinsonii. 



This seed has been examined by Brill (see Table 1 and refer- 

 ences) , who concluded that it contained chaulmoogric or hydno- 

 carpic acids. Our results, as will be seen, are not in accord 

 with this conclusion. The species is widely distributed in the 

 Philippines and neighboring islands. Our samples were ob- 

 tained from Zamboanga. 



TARAKTOGENOS KURZII KING 



This seed, the official chaulmoogra, is quite different from 

 Hydnocarpus wightiana in external appearance, being smooth
