A species related to, and ])reviou.sly identified wilii Hindora iralliahW i'lcntli. 

 (/S'. icallichiana Bentli.) of tlie Malayan Peninsula, dilTering 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. tcallichiana. 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 l<ii()\\n 

 in the Philippines. 



The timl)er of this tree is liard and of a jellowisli (ir rcddisli color, hciiig used 

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

 valuable "Ipil" wood (httsia hijuf/a O. Ktze.). From 1900 to 1904 su])a ranked 

 fourteenth in amount received in the local lund)er markets, witli a total of 

 177,189 feet B. M., its average price for sawed lumber being $81.50, I'nited 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, somewliat fragrant oil which burjis with 

 a. clear flame. Tliis has been discussed by Clover" sub Sindora iniUicliH. 



From a report submitted to the Chief of the Forestry Bureau by Mr. I\()bl)e, 

 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 hacked with bolo cuts as high as a 

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

 so i)laccd as to catch tlie jirodnct. Tlie oil seems to be a product of the entire 

 woody ])ortion of the tiee and does not flow from any ])articular 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. Wlicn 

 the trees are slashed for gathering the oil, the first tliat 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 tlie uianiifacturc of 

 paint, especially for use on shi])s, varnish for saill)oats, etc., and as an ilhiiiii- 

 nating oil."
