Diagnosis

Transition from early- to latewood abrupt. Earlywood tracheids much wider than the latewood tracheids. Bordered pits arranged in a single vertical row in the radial cell walls of the earlywood tracheids. Apertures round. Axial parenchyma present and diffuse. Rays uniseriate and multiseriate. Multiseriate rays containing resin ducts up to four cells wide. Horizontal and tangential ray cell walls thin and pitted; 2 – 6, commonly 3 – 4, piceoid crossfield pits present in each cross-field. Ray tracheids located at margins and interior of rays. Cell walls mainly smooth, occasionally showing small dentations and bordered pits on the radial walls. Vertical and horizontal resin ducts surrounded by up to 8 thick-walled epithelial cells.
