Vernac. name. — Ibegogo (Cent. Prov. S. Nigeria, Unwin). 



The seeds of this species are believed to yield the " Touloucouna " 

 oil of West Africa, although, in view of the general similarity of 

 the oil of several of the known species of Carapa, it is possible 

 that the name may be largely a geographical one. The uses in 

 Africa appear to be identical with those of the preceding species. 

 The seeds, under the name of " Krufie," have recently been 

 received at Kew from West Africa, where the oil, which is 

 extracted by grinding and boiling, is used for the cure of yaws, 

 burns, and mosquito bites (Mus. Kew). In Marseilles the oil is 

 used for soap-making (Planchon & Collin, Drog. Simpl. ii. 

 p. 670). 



Heckel gives an analysis of " Touloucouna " oil, in comparison 

 with that of " Carapa " oil, and is of the opinion that they are 

 distinct products. {See Les Graines Grasses Nouvelles ou peu 

 connues des Colonies Francaises, Paris, 1902, pp. 141-153.) 



Lewko witsch, however, is of the opinion that there is not sn fficient 

 justification for considering " Carapa " oil and " Touloucouna" oil 

 as two different individuals in view of the uncertainty attaching 

 to the origin and to the original condition of the fats. {See Carapa 

 oil in the Analyst, May, 1908.) 



The bark possesses tonic and febrifugal properties. 



There is no specimen of the wood at Kew, but it is possible that 

 it is somewhat similar to that of C. guianensis — the only other 

 known species of Carapa {C. grandiflord) from Tropical Africa has 

 much the same appearance and general characters. It is strong, 

 durable, and capable of taking a good polish. The specific gravity 

 by experiment is *6061, and the weight per cubic foot by calculation 

 is 37*8 lbs. (Mus. Kewj. Wood believed to belong to C. procera 

 has been valued on the English market at 2^cl to 3^d. per foot, as 

 a timber with some of the qualities of both cedar and mahogany, j 



Seeds are said to be produced very freely, and the tree is very 

 common in the Central Province (Kew Bull. 1908, p. 194).
