A small tree with oblong, ovate, somewhat harsh, oblique, 
acuminate leaves; small axillary inflorescences of very numerous 
minute flowers; and small, fleshy, ovoid drupes; very common 
and widely distributed in settled areas of the Philippines, 
Trema orientalis bast strips are cinnamon in color. They 
average 3 millimeters wide and 0.38 millimeter thick. The 
strands average nine strips thick. Plate V, fig. 5, shows that 
the strips are very irregular and ragged looking. 
When dry, rope made of Trema orientalis has the lowest ten- 
Sile strength and breaking length of all ropes tested. However, 
when wetted, its resistance is nearly doubled. Even so, the 
tensile strength islow. Filipinos say that this bast is very weak, 
and that it makes a poor rope. For this reason it is not com- 
monly used for the fabrication of cordage. 
A summary of the tests of this species made in the Bureau 
of Science is given in Table XXXVIII.
