Alstonia macrophylla

It is native to Indonesia (Kalimantan and Sulawesi), Malaysia, the Philippines (Tagalog: batino[4]), Thailand, and Vietnam.

Leaf-blades are 10 to 50 centimeters long, 5 to 15 cm wide, widest in or above the middle, and cuneate at the base.

Fruits are about 30 centimeters long, green and filled with many small hairy seeds that are dispersed far and wide by the wind.

The heartwood is yellowish, with a straight and shallowly interlocked grain with a moderately fine to rather coarse texture.

[6] In Sri Lanka, where it is called "havari nuga", it has been used for reforestation due to its fast growth rate and is now a widely spread invasive species in the wet zone.
