DESCRIPCIÓN DEL ÁRBOL
Descripción botánica
It is a dioecious, small to medium-sized tree up to 30 m tall. The bole is straight, branchless for up to 20 m, up to 60 cm in diameter, sometimes with small buttresses.
Hábitat natural
Haplolobus floribundus is found mostly scattered in primary, rarely secondary rainforest, from the sea level up to 1,980 m of altitude. It is most common on hills and ridges, and it generally occurs on well drained, alluvial or clayey soils.
Usos No-maderables
H. floribundus wood is reported to have an exceptional wide range of density variation, from 0.34 up to 1.24 g/cm3 in air dried condition.
