51766. Canartum sp. Balsameacese. 



" No. 23. Native to China and sold in the markets at Singapore. The 

 seed is edible, Uke the pili nut of the Philippines." 



51767. Carapa guianensis Aubl. Meliacese. Crabwood tree. 



"No. 4. A tall tree with large leaves and large globose fruits contain- 

 ing many angular and variably shaped fawn-colored seeds. It is known 

 as the crab-oil tree and is a native of Guiana and tropical Africa. It is 

 cultivated in Singapore." 



This tree, which has large ovate leaves, bears triangular nutlike fruits, 

 ripening in June, July, and August ; when crushed these e?:ude a rich oil. 

 This oil appears to be equal in lubricating value to ordinary machine oil, 

 and it should be utilized. The cakes from which the oil has been ex- 

 pressed might serve as cattle feed. The tree grows in commercial quan- 

 tities throughout the lower Amazon regions. The wood excels mahogany.
