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

Local names: Anubing (Nueva Ecija, Tarlac, Zambales, Rizal, Laguna, ‘ 
Tayabas, Camarines, Sorsogon, Mindoro, Nueva Ecija, Sibuyan) ; anubling 
or kanubling (Camarines, Albay, Sorsogon); bayuko, isis (Negros, Iloilo) ;

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 Bajos. 
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. , 
Artocarpus 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 Artocarpus is 
used locally in compounding bird lime.
