Perkins and Cruz: Oils in Chaulmoogra Group 545 



1 SEEDS USED 5 

 GYNOCARDIA ODOEATA R. BROWN 



This seed is found in the forests of Assam, where it is even 

 now confused with Taraktogenos kurzii. Although Power and 

 Barrowcliff found the Gynocardia oil to be entirely different 

 from Taraktogenos oil (see Table 1), this oil was included in 

 our study because of the contradictory report of Brill and 

 Williams 6 on a sample of "Gynocardia odorata" purchased 

 through the Department of Agriculture, Assam. We have not 

 only confirmed Power's results, but have, like Brill and Williams, 

 found it difficult to obtain genuine Gynocardia seeds from As- 

 sam. This is surprising in view of the easy distinction pointed 

 out by Muir. 7 The radical of the Gynocardia seed is lateral, 

 while that of the Taraktogenos and Hydnocarpus is terminal. 



The Gynocardia seeds used in this study were purchased from 

 a Calcutta firm. 



This is the largest Hydnocarpus seed known to us and is the 

 only Philippine species which we have succeeded in obtaining 

 in commercial quantities. Our supply has been obtained from 

 the Provincial Treasurer of Albay (samples A and C), and 

 from ex-Governor Timoteo Alcala of that province (sample B). 

 The local names are dudoa and dudu-dudu. The fruit is about 

 20 centimeters long and 10 to 12 centimeters in diameter. The 

 seeds are about 3 centimeters long. January and February 

 seem to be the best months for collecting this fruit. 



This well-known seed, lukrabao (lukrabo), is found exten- 

 sively in Indo-China. Our samples were purchased from a 

 Bangkok firm. 



'Botanical and economic data on Gynocardia odorata, Hydnocarpus an- 

 thelminthica, H. castanea (of which we have no specimens for this study), 

 and Taraktogenos kurzii have been reported by J. F. Rock in The Chaul- 

 moogra Tree and Related Species, Bull. U. S. Dept. Agr. 1057 (1922).
