This is the species of Canarium referred to by Welwitsch, Apont. 

 p. 565 under n. 156, which he states has two large stipules at the base 

 of each leaf ; unless these are to be considered as the lowest pair of 

 leaflets, the plant is exceptional in the Family, the leaves of which are 

 characterised as exstipulate. 



The Gum Elemi trickles down in great quantity from incisions made 

 in the trunk, and the natives employ the resin, which possesses a 

 peculiar aromatic smell, in the form of a plaster to cure wounds ; they 

 also frequently bring it to the markets at the coast, where the druggists 

 and other colonists buy it at the price of 100 to 200 milreis per lb., and 

 at times at a much dearer rate, for similar purposes. The fruit is oily, 

 and serves the natives to season various comestibles. The Mubafo 

 occurs in the primitive forests in the districts of Cazengo and Pungo 

 Andongo, and in greater abundance in that of Talamungongo and 

 neighbouring territories. The powdered bark is used by the natives 

 iu the treatment of syphilitic and scorbutic ulcers. (See Welwitsch, 

 Synopse, p. 35, n. 94, and p. 56, n. 149.) 



There is a poor specimen from the Island of St. Thomas, a woody 

 branch without either flower or fruit, which perhaps belongs to the 

 genus Canarium ; the local name is " Pao Oleo." No. 6770.
