- 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.
