Original diagnosis/description

Wood ring-porous with distinct growth ring boundaries. Tangential and radial diameter of vessels 55 (32–75) μm and 82 (33–136) μm in earlywood, 22 (8–43) μm and 30 (15–50) μm in latewood (Acarca Bayam et al., 2018). Vessels generally solitary, rarely in groups of 2–3 cells. Vessel frequency 40–100 per mm2 (Pl. 13A, B). Axial parenchyma present, scanty paratracheal, in marginal or apparently marginal bands (Pl. 13C). Rays of two distinct sizes, as 1–2 rows and 4–10 rows. Larger rays generally wide, 7 (5–8) cells wide, longer rays more than 1 mm high, narrow rays uniseriate (very rarely biseriate). Number of rays 4–12 per mm (Acarca Bayam et al., 2018) (Pl. 13D, E). Rays heterocellular with procumbent body ray cells and one or more rows of upright and/or square marginal cells (Pl. 14A, C, E). Perforation plates simple (Pl. 14B). Prismatic crystals present in rays (Pl. 14C). Intervessel pits alternate (Pl. 14D) or rarely slightly opposite.
