Morus trees are described as small to fairly large, reaching up to 35 m in height and 150 cm of diameter, without buttresses.
Morus macroura is found in evergreen rain forests, often on volcanic soils, between 400 to 2,500 m of altitude.
Occasionally vessels in tangential pattern. Occasionally vessels in diagonal and/or radial pattern. Wood semi-ring porous and/or ring porous. Occasionally vessels of two distinct diameter classes, wood not ring-porous. Occasionally vessel clusters common. Tylo Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in non-chambered axial parenchyma cells. Two cells per parenchyma strand. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally rays of two distinct sizes. Larger rays more than 4 seriate. Occasionally sheath cells. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Body ray cells procumbent w Fibers very thin walled.

Ease of Drying: Kelat timber air dries slowly to very slowly. In Malaysia boards 15 mm thick are reported to dry in 5 months. Drying Defects: The timber is liable to end-splitting and checking. Kiln Schedules: Kiln drying requires a mild schedule. Pre-drying before kilning is advised to prevent serious degrade.
