Description Of The Tree
Botanical Description
It is a deciduous, small to medium-sized or occasionally fairly large tree up to 30 m tall. The bole is usually straight, cylindrical, branchless for up to 12 m, with a diameter of 120 cm and buttresses up to 3 m high.
Natural Habitat
It is reported in primary and secondary, often periodically dry or very dry monsoon forests and thickets, and in lower montane rainforests, up to 1,200 m of altitude.
Natural Distribution
It is present but nowhere abundant, in the Philippines, Indonesia, New Guinea, northern Queensland, around Honiara in Solomon Islands and throughout Melanesia.
Wood Identification
Anatomic Description Of Wood
Vessels per mm2 5 to 20. Wood diffuse porous. Tyloses common. Tangential diameter of vessel lumina 100 to 200 micras. Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits medium, 7 to 10 micras. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in non-chambered axial parenchyma cells. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II) Fibers with simple to minutely bordered pits. Septate fibers present.
