URENA LOBATA Linn. Kollokollot. 
Local names: Afulut (Gaddanes in Nueva Vizcaya) ; anonongkot (Bi- 
col) ; dalupang (Visayan, Culion) ; kol-lokollot (Amburayan, Ilocos Sur, 
Nueva Vizcaya, Pangasinan, Tarlac) ; kollolot (Abra) ; kolot-kolotan, kulut-

kulutang, dalupang (Negros) ; mangkit (Tayabas) ; piiot-sinuang (Isinai 
in Nueva Vizcaya); puriket (Abra). 
An erect, branched, shrubby plant, 0.5 to 2 meters high, with 
ovate to orbicular, usually lobed, leaves ; pink flowers ; and small, 
globose, shiny fruits; a weed in the settled areas throughout 
the Philippines; abundant. 
In India (Assam and Burma) Urena lobata, which is said 
to grow sometimes 8 feet high, is used as a cordage material. 
It is a flber of the jute type and is said to be more easily ex- 
tracted than jute. Urena lobata is one of the three important 
textile flbers known to the natives of Madagascar.^® They make 
rope, twine, and mats from the bast. In the manufacture of 
coffee bags it is said to be an excellent substitute for jute be- 
cause the fiber has no influence on the aroma of the coffee.-'
