Wood-anatomical description (IAWA hardwood codes):
*Growth rings: (1: growth ring boundaries distinct); (2: growth ring boundaries indistinct or absent). *Vessels: 5: wood diffuse-porous; 13: simple perforation plates; 22: intervessel pits alternate; 23?: shape of alternate pits polygonal; 24: intervessel pits minute (<font size="1">≤</font> 4 μm); 25: intervessel pits small (4–7 μm); 30: vessel-ray pits with distinct borders; similar to intervessel pits in size and shape throughout the ray cell; 42: mean tangential diameter of vessel lumina 100–200 μm; 47: 5–20 vessels per square millimetre; 58: gums and other deposits in heartwood vessels. *Tracheids and fibres: 61: fibres with simple to minutely bordered pits; (65: septate fibres present); 66: non-septate fibres present; 69: fibres thin- to thick-walled. *Axial parenchyma: 78: axial parenchyma scanty paratracheal; 79: axial parenchyma vasicentric; 80: axial parenchyma aliform; (81: axial parenchyma lozenge-aliform); (82: axial parenchyma winged-aliform); 83: axial parenchyma confluent; 85: axial parenchyma bands more than three cells wide; (86: axial parenchyma in narrow bands or lines up to three cells wide); 89: axial parenchyma in marginal or in seemingly marginal bands; 92: four (3–4) cells per parenchyma strand; 93: eight (5–8) cells per parenchyma strand. *Rays: (97: ray width 1–3 cells); (98: larger rays commonly 4- to 10-seriate); (104: all ray cells procumbent); 106: body ray cells procumbent with one row of upright and/or square marginal cells; 115: 4–12 rays per mm. *Storied structure: (118: all rays storied); 122: rays and/or axial elements irregularly storied. *Secretory elements and cambial variants: 131: intercellular canals of traumatic origin. *Mineral inclusions: 136: prismatic crystals present; 137: prismatic crystals in upright and/or square ray cells; 141: prismatic crystals in non-chambered axial parenchyma cells; (142: prismatic crystals in chambered axial parenchyma cells).
