DESCRIPCIÓN DEL ÁRBOL
Descripción botánica
It is a large tree, with boles of 10 to 20 m. The bole is long, cylindrical, distinctly tapering, erect or straight at times crooked or bent. The buttresses are very low, almost absent, rounded.
Hábitat natural
It occurs in low altitudes, up to 1,000 m of altitude, in humid mixed rain forests.
Distribución natural
It is probably a native of the Pacific, New Guinea, northern Queensland and the Malay Archipelago but naturalized in Hawaii, Sri Lanka and New Caledonia.
Usos No-maderables
The sawdust may cause allergic reactions like sore throat and headache.
IDENTIFICACIÓN DE LA MADERA

Defectos por secado
Ease of Drying: Air seasoning is reported to be easy and rapid, without seriously degrade. Drying Defects: It often darkens considerately on drying. Kiln drying may result in slight warping and splitting. Kiln Schedules: Schedule recommended for Lampati. For lighter color timbers USDF schedule T10-D5S or UK schedule J are recommended.
