The Anahaw leaf! Scientific name: Livistona rotundifolia.

"It is the leaf of a palm tree variety whose straight durable trunk is highly in demand for poles and pillars, flooring, pack carriers, fishing rod bows,
canes and spear shaft ... in recent years has proven its viability as a good material in the manufacture of floor tiles ... ecologically can purify air,
has a cooling effect, improves water supply, and its roots hold the soil" (by Rudy A. Fernandez - "The Philippine Star", January 8, 2008).
