Piassava

 

a stiff fiber from the leaf sheaths of several species of tropical palm, including the American Leopoldinia piassaba, the African Raphia vinifera, and the Asian Borassus flabellifer. The fibers, which are formed by the vascular bundles, are 0.5-3.5 mm thick and 0.5-1.8 m long. They range in color from straw to almost black. The fibers result from the natural maceration of the sheaths of fallen leaves. Piassava is used for making brushes, mats, and ropes.

Attalea funifera (piassava or piacava) is endemic to a belt along the Atlantic coast of Bahia in Brazil (Figure 1) where it mostly inhabits sandy and spodosolic soils on elevated terraces close to the sea.

Perhaps more important, though, is the fact that the local people are largely engaged in limited subsistence activities, such as the ornamental fishes and piassava (palm fiber) trade, which generate enough cash to provide for basic necessities.
