ARTOCARPUS COMMUNIS Forst. Antipolo. 
Local names: Antipolo (Bataan, Cagayan, Laguna, Manila, Mindoro, 
Palawan, Rizal, Union, Zambales) ; antiponong lalaki (Rizal) ; kamanst 
(Leyte) ; pdkak (Cagayan, Ilocos Sur, Union, Zambales) ; pasak (Abra, 
Ilocos Sur, Union); tipolo (Camarines, Negros). 
A tree with abundant milky juice; very large, pinnately lobed 
leaves; and large, globose, fleshy, many-seeded, rough fruits; 
the male flowers minute, very numerous, in large, dense, oblong- 
ovate, solid inflorescences; common and widely distributed in 
the Philippines, cultivated and wild. 
This bast is a striking example of the different properties 
that a fiber may assume, depending upon the age of the plant 
from which it is taken, in contrast to variation in its appearance 
and properties due to the manner of its manipulation and prepa- 
ration, as described under Abroma fastuosa. 
Plate IV, fig. 9, shows a sample of rope made from bast 
from the trunk of an old tree obtained in April, 1916, at Sappaac, 
Abra Province. Plate I, fig. 1, illustrates this particular piece 
of rope in the process of manufacture. The strips of bast 
are chestnut in color, are about 1.5 meters long, and are ex- 
ceedingly hard and stiff. 
Owing to the excessive labor required in the preparation of 
the mature bast it is seldom used for making rope, though for 
some purposes it excels all other fibers in durability. After 
the old bast has been stripped, it must be beaten a long time 
in order to give it a small degree of pliability. The bast is
