212 PHILIPPINE RESINS, GUMS, AND OILS 



The yield of oil, calculated from the weight of the whole fruit, 

 was 0.56 per cent and from the peel alone 1.29 per cent. The 

 oil has been employed as an ingredient of shampoos. 



The tree is said to bear fruits within five years after planting. 

 The fruits are produced during the entire year, but most abun- 

 dantly during the rainy season. In places where they are grown 

 they sell for 5 centavos per hundred during the wet and 20 

 centavos per hundred during the dry season. Samuyau is said 

 to be very delicate, and to need careful attention, and in Cebu, 

 during the dry season, even daily watering.

GURONG-GURO 



This species has a very fragrant rind which is mixed with 

 coconut oil for use on the hair. The whole fruit is also mixed 

 with gogo {Entada phaseoloides) bark as a shampoo. Cloves 

 are sometimes put into the rind and then the fruits squeezed 

 in the hands to give them a pleasant odor. The fruit of this 

 species is about 5 centimeters in diameter, with a very rough, 

 irregularly ridged, green rind, and with a nipple-like protuber- 

 ance at the base. The rind is rather thin, and the fruit is not 

 edible.
