A shrub or small tree, nearly glabrous; leaves oblong to 
oblong-ovate, up to 14 centimeters in length, often somewhat 
inequilateral, 3-nerved from the base; flowers in axillary um- 
bels; fruit small, somewhat fleshy, obovoid, about 6 centimeters 
long, glabrous; common and widely distributed in the Philip- 
pines at low altitudes. 
This bast is very common in the Ilocano provinces and is 
said to make a very durable rope for dry-weather use. Grewixi 
multiflora is a pale yellow-orange, nonstaining fiber. The strips 
are soft; they average 6 millimeters wide, 0.46 millimeter thick, 
and 2,104 millimeters long. Each strand averages seven strips 
thick. Grewia multiflora makes a rope of more than average 
pliability, but of low tensile strength and breaking length. Im- 
mersion in water for twenty-four hours reduces the mean ten- 
sile strength 12 per cent. The five wet specimens gave more 
discordant strength values than the five dry ones, the greatest 
variation in the latter being 13, and in the former 29 per cent, 
from the mean. Three test pieces in each series failed in eye- 
splices, the maximum value in both series being given by spec- 
imens breaking in an eye-splice. The minimum value of the five 
dry specimens was obtained from a test piece that ruptured 
in the unspliced portion of the rope, whereas the minimum value 
of the five wet test pieces was given by a specimen that failed 
in an eye-splice. 
A summary of the tests of this species made in the Bureau 
of Science is given in Table XXVII.
