Original diagnosis/description

Growth rings distinct. Wood ring porous. Vessels in earlywood mostly solitary, a few radial or oblique multiples of 2–3 (mostly 2); latewood vessels mostly in radial multiples of 2–5 (mostly 2–3), few clusters and solitary. Perforation plates simple. Helical thickenings only in narrow vessels. Tyloses not observed. Intervessel pits crowded, alternate, vestured. Fibers non-septate, pits not observed, thin- to thick-walled. Vessel-ray pits similar to intervessel pits in shape and size. Parenchyma confluent, paratracheal vasicentric, aliform with short wings, frequently unilateral. Long crystalliferous parenchyma strands common. Rays 1–7 cells wide, exclusively homocellular, only composed of procumbent cells.
