Growth rings distinct. Diffuse-porous to semi-ring-porous. Vessels mostly solitary, but also in occasional radial, oblique, or tangential pairs; tangential diameters average <100 μm; perforations simple and scalariform; intervessel pits opposite, transitional to scalariform; pits to ray parenchyma oval to horizontally elongate, with reduced borders. Non-septate fibers with distinctly bordered pits on radial walls. Axial parenchyma diffuse and diffuse-in-aggregates as short uniseriate bands. Rays uniseriate and multiseriate, tending to be of two sizes, wider multiseriate rays >10-seriate; wide rays irregularly spaced; average multiseriate ray height >1 mm; homocellular to heterocellular, body composed of procumbent cells with marginal rows of square and upright cells. Solitary rhomboidal crystals occasional in procumbent ray cells. Storied structure absent.
