Diagnosis
Wood diffuse-porous. Vessels mostly solitary with a tendency to form radial iles, less than 100 μm in tangential diameter, fewer than 40 per mm2; perforations exclusively scalariform, with fewer than 40 bars; intervessel pits mostly opposite, vesselray parenchyma pits similar to intervessel pits. Abundant diffuse-in-aggregates axial parenchyma. Multiseriate rays more than 4 cells wide, with a tendency to two sizes of ray cells. Wood with more than 50% parenchyma by volume. Imperforate elements with distinctly bordered pits in radial and tangential walls.
