Wood diffuse porous. Occasionally tyloses common. Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits large, 10 micras or more. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Siliceous bodies in the axial parenchyma cells. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. Occasionally axial parenchyma 4 to 10 rays per mm (medium). Ray height more than 1 mm. Larger rays more than 4 seriate. Silica bodies in the ray cells. Prismatic crystals in the ray cells.
