|Naming and discovery|
The plant itself is 35 meters high with brownish-orange bark. The leaves are arranged in a spiral formation.
The heartwood of X. melanoxylon, known by the locals as tubi is a dark, thick wood. More demand for the tubi has left the species to be conserved.
It was named for Greek melas -anos, meaning black, and xylon, wood, referencing the dark heartwood, tubi.
As demand for the tubi inside the plants increases, more of these plants are being killed. The plant now has a legal paper on protection.
