A species related to, and previously identified with Sindora iralliehii Benth. 
(S. u'ullichiana Benth.) of the Malayan Peninsula, differing from that s])ceies 
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 liave accordingly de- 
scribed the Philippine plant as a distinct species, using tor the s]»ecifie name the 
Tagalog name “Supa,” by which this iiniaatant timber tree is universally known 
in the Phili[)pines. 
The timber of this tree is hard and of a j'ellowish or reddish color, being used 
in naval and general constructions, and is frequently substituted for tlie more 
valuable “Ipil” wood (Intsia hijufja 0. Ktze.). From 1900 to 1904 supa ranked 
fourteenth in amount received in the local lumber markets, with a total of 
177,189 feet B. M., its average pi'ice 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-j'ellow, somewhat fragrant oil which burns with 
a clear flame. This has been discussed by CJover” sub Hindora iralliehii. 
From a report submitted to the Chief of the Forestry Bureau by IMr. Kobbo, 
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 placed as to catch the product. The oil seems to be a product of the entire 
woody portion of the tree and does not ilow from any particular portion siich 
as the sap wood only. If an auger hole be bored into the heart of a li\ing 
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 lii'c. 
the heat causing a great increase in the flow of oil.” 
“The oil is not widely used. Tliere is a demand for it for the manufacture of 
paint, especially for use on ships, varnish for snillioats, etc., and as an illumi- 
nating oil.”
