70 PHILIPPINE RESINS, GUMS, AND OILS 



shoot bears two or four large leaves, which are variable in size. 

 The leaves are rather narrow, pointed, and up to 35 centimeters 

 in length and 7 centimeters in width. The flowering shoots are 

 20 to 25 centimeters in length and leafless. The flowers are pale 

 pink to purple, about 1 centimeter long and numerous. 



This species is widely distributed in the Philippines and is also 

 found in Formosa. It occurs particularly in thickets and open 

 places.

 ARTOCARPUS CUMINGIANA Tree. (Fig. 23). Anubing. 



Local names: Anubing (Nueva Ecija, Tarlac, Zambales, Rizal, Laguna, 

 Tayabas, Camarines, Sorsogon, Mindoro, Nueva Ecija, Sibuyan) ; anuhling 

 or kanubling (Camarines, Albay, Sorsogon) ; huyuko, isis (Negros, Iloilo) ; 

 kalaudhan (Bontoc) ; kamanddg (Cagayan) ; koliung (Abra) ; kubi (Ta-

ANUBING GUM 



The latex of this species would appear to be promising material 

 for chewing gum. 



This species has been grown in plantations at Los Banos. 

 Two separate lots of seeds were planted. In one case the percent- 

 age of germination was 61.7 and in the other 28.7. At the end 

 of 7 years the average rate of growth was 2.5 meters. 



Artocavpus cumingiana is a tree reaching a height of about 30 

 meters and a diameter of about 100 centimeters. The leaves are 

 alternate, hairy, pointed or slightly heart-shaped at the base, and 

 average 20 centimeters long, and 10 centimeters wide. The 

 petioles are 1 to 2 centimeters long. The male heads are pear- 

 shaped and 1 to 2 centimeters long. The female heads are 

 rounded and nearly 2 centimeters in diameter. 



This species is distributed from northern Luzon to Mindanao. 



ARTOCARPUS ELASTICA Reinw. (Fig. 24). GuMIHAN. 



Local names: Antipolo (Tayabas, Samar) ; gumihan (Camarines, Albay, 

 Sorsogon); tugup (Surigao, Davao). 



GUMiHAN GUM 



The latex of this tree hardens into a somewhat brittle sub- 

 stance resembling in color and consistency the stick chewing 

 gum put on the market years ago, before it was blended with 

 sugar and flavored. As far as is known, the gum of Artocarpus 

 elastica has not been collected in quantity nor has any analysis 

 been made of it. The latex of some species of A7'tocarpics is 

 used locally in compounding bird lime.
