A species related to, and previously identified with Sindora wallichii Benth. 

 (S. uallichiana Benth.) of the Malayan Peninsula, differing from that species 

 in its glabrous leaves, and larger pods. Dr. Prain, director of the Royal Gardens, 

 Kew, has examined some of the material cited above and informs me that this 

 species is not identical with Bentham's 8. wallichiana. I have accordingly de- 

 scribed the Philippine plant as a distinct species, using for the specific name the 

 Tagalog name "Supa," by which this important timber tree is universally known 

 in the Philippines. 



The timber of this tree is hard and of a yellowish or reddish color, being used' 

 in naval and general constructions, and is frequently substituted for the more 

 valuable "Ipil" wood {Inlsia bijuga 0. Ktze.). From 1900 to 1904 BUpa ranked 

 fourteenth in amount received in the local lumber markets, with a total of 

 177,189 feet B. M., its average price for sawed lumber being $81.50. United States 

 currency per 1.000 feet B. M. 



In addition to being a valuable timber tree, supa also yields considerable quan- 

 tities of straw-colored or light-yellow, somewhat fragrant oil which burns with 

 a clear flame. This has been discussed by Clover 13 sub Sindora wallichii. 



From a report submitted to the Chief of the Forestry Bureau by Mr, Kobbe. 

 forester, the following extracts are taken: 



"This oil (supa) is secured from the trunk of the living tree and not from 

 the fruit or dead wood. The tree is usually backed with bolo cuts as high as a 

 man can reach and the oil runs down the channels so formed, into some vessel 

 so placed as to catch the product. The oil seems to be a product of the entire 

 woody portion of the tree and does not flow from any particular portion such 

 as the sap wood only. If an auger hole be bored into the heart of a living 

 tree, as much as 10 liters of oil is frequently obtained from the one hole. When 

 the trees are slashed for gathering the oil, the first that exudes is set on fire, 

 the heat causing a great increase in the flow of oil." 



"The oil is not widely used. There is a demand for it for the manufacture of 

 paint, especially for use on ships, varnish for sailboats, etc.. and as an illumi- 

 nating oil."
