38 PHILIPPINE RESINS, GUMS, AND OILS 



Family LEGUMINOSAE 



Genus SIN DORA 



SINDORA INERMIS Merr. (Fig. 9). Kayu-gAlu. 



Local names: Kayu-gdlu (Cotabato) ; "parind (Albay) ; sinsud (Jolo, 

 Manukmangka Island, Sibutu Island). 



KAYU-GALU OIL 



The trunk of this species yields a resinous oil known as kayu- 

 galu oil. It has a pleasant, persistent odor and should be useful 

 as a perfume oil. Locally it serves much the same purposes 

 as the oil of supa from Smdora supa. It has been exported in 

 small quantities to Singapore by Chinese traders in Zamboanga. 



Sindora inermis is a tree reaching a height of about 30 meters 

 and a diameter of about 75 centimeters. The leaves are alter- 

 nate and pinnate with four to eight leaflets, which are opposite, 

 leathery, smooth, somewhat rounded at the base, usually pointed 

 at the tip, and from 5 to 10 centimeters in length. The flowers 

 are borne on compound, hairy inflorescences. The fruit is flat- 

 tened, somewhat inequilateral, about 7 centimeters long, and 5 

 centimeters wide. Sindora inermis is distinguished from Sin- 

 dora supa by the fact that the fruit of Sindora inermis is not 

 armed with spines as is the case with that of Sindora supa. 



This species is distributed from southern Luzon to Mindanao 

 and Jolo. 



SINDORA SUPA Merr. (Fig. 10). Supa. 



Local names: Ma7idpo, yakdl-dildu, halayong (Tayabas) ; supd (Taya- 

 bas, Camarines, Albay, Zamboanga). 



SUPA OIL 



Oil of supa is obtained from this tree by making a cavity in 

 the trunk. Clover * says that a freshly cut tree will yield about 

 10 liters of oil. The oil is non-drying, limpid, light yellow, 

 homogeneous, with a slight fluorescence, possesses a pleasant 

 aromatic odor, and does not become rancid. This oil is highly 

 prized by the Filipinos for illuminating purposes and for the 

 treatment of skin diseases. The oil of supa can be utilized in 

 making varnishes, paints, transparent paper, and for the adul- 

 teration of other oils.
