284 PHILIPPINE FIBER PLANTS 
Genus GREWIA 
GREWIA ACUMINATA Juss. AMBOI-UAN. 
Local names: Allagat, alinau (Union) ; alagosi (Negros) ; bagun, balagan 
(Palawan) ; balovgo dilang-ahas (Zamboanga) ; amboi-udn (Union). 
Bast fibers are extracted from the bark of this tree and made 
into ropes and strings. ; 
Grewia acuminata is a tree reaching a height of about 10 
meters and a diameter of about 15 centimeters. The leaves are 
alternate, somewhat hairy, pointed at the apex, rounded at the 
base, with toothed margins, and 8 to 15 centimeters long. The 
flowers have whitish petals and prominent yellow stamens, and 
are borne on compound inflorescences. The fruit is green, about 
2 centimeters in diameter, frequently somewhat four-lobed, four- 
seeded, and very hairy. 
This species is distributed from La Union Province in Luzon 
to southern Mindanao. 
GREWIA BILAMELLATA Gagnep. BENGLARENG. 
Local names: Benglaréng (Iloko, Itneg); dongraréng (lloko); duraréng 
(Abra). 
The bark is used for making a rope of slight strength. King 
found the tensile strength to be 320 kilos per square centimeter ; 
wetting decreasing it 44 per cent. The rope is said to be durable 
during the dry season, but to deteriorate rapidly during wet 
weather. 
GREWIA ERIOCARPA Juss. (G. negrosensis). BARIU-AN. 
Local names: Anildu (Cebu); balibdgo, kanas-kandas (Batangas); bali- 
liunan (Zambales); balitnéng (Ilocos Norte, Capiz); baria-an (Union) ; 
bariu-dn (Iloko, Itneg, Abra, Union, Pangasinan, Nueva Ecija); baruan 
(Lepanto); danli (Tayabas); dirdn (Union); durdn (Pangasinan); ked- 
déng (Ilocos Sur, Abra, Union); lapi, lapni, lapnit (Cagayan); masaplak 
(Pampanga). 
A rope of average strength is made from the bark of this tree. 
The fiber is extracted from the bark as soon as it is removed from 
the tree. The rope is used for hauling, tying cattle, and binding 
rice bundles. In Abra the fiber is used to some extent in making 
hat braids. King found rope made from the bast to have a 
tensile strength of 394 kilos per square centimeter. Wetting 
weakened it about 3 per cent. 
Grewia eriocarpa is a shrub or small tree. The leaves are 
alternate, densely hairy, pointed at the tip, oblique at the base, 
from 5 to 15 centimeters in length, and with the lower surface 
white or nearly so. The flowers are small and yellow. The 
fruit is small, round, bluish, and edible.
