_XIV, 6 King: Philippine Bast-fiber Ropes 627 
FICUS PACHYPHYLLA Merr. Balete. 
Local names: Baliti (Laguna); lunug (Occidental Negros); pasakia 
(Abra, Itneg). 
A strangling fig with very coriaceous, glabrous, somewhat el- 
liptic, rather densely nerved leaves and nearly globose axillary 
fruits; of local distribution at low altitudes and widely distri- 
buted in the Philippines. 
Like Ficus forstenii bast, that from Ficus pachyphylla also is 
characterized by finely frayed filaments that cover the surface. 
The strips of bast are uniformly pecan brown; they average 2 
millimeters wide, 0.28 millimeter thick, and 838 millimeters 
long. Each strand averages eight strips thick. 
Rope made of Ficus pachyphylla has good strength, particularly 
when wetted. When dry it has a medium tensile strength and 
breaking length, but after immersion in water for twenty-four 
hours its tensile strength is increased 17 per cent. However, the 
results are discordant, the maximum variation from the mean 
of the five specimens being 25 per cent. The dry tensile- 
strength values showed better agreement, the maximum varia- 
tion from the mean being 16 per cent. Four of the five dry, 
and three of the five wet, test specimens ruptured in eye-splices. 
Filipinos say that rope made of this bast is very durable. 
A summary of the tests of this species made in the Bureau of 
Science is given in Table XXXII.
