Wood diffuse–porous. Growth rings present marked by marginal parenchyma bands. Vessels small to medium, mostly medium in size, tangential diameter range 87–166 μm, mean 133 μm, solitary and in radial multiples of 2–5, evenly distributed, 8–10 per sq mm, usually round to oval, tylosed; vessel members range 180–362 μm, mean 271 μm, with transverse to oblique ends, occasionally storied; perforations simple; intervessel pits bordered, alternate, 6–8 μm, with lenticular apertures. Axial parenchyma both paratracheal and apotracheal, paratracheal vasicentric to aliform–confluent, apotracheal diffuse. Rays 7 to 8 per mm, 1–4 (mostly 2 to 3) seriate, storied, uniseriate rays about 25 μm in width and up to 280 μm in height, multiseriate rays 27–61 μm in width and 9–23 cells or 185–482 μm in height, ray to ray fusion present, homo to heterocellular, usually made up of procumbent cells, with 1 row of upright or square cells; ray tissue weakly heterogeneous. Fibres thick–walled and non–septate.
