- Diagnosis
- Dis-tinct growth rings, wood semi-ring-porous, usually with solitary vessels and radial multiples of 2-3(7). Solitary pores oval-polygonal, thick-walled, of 2-3 μm simple wall or 5-8 μm double wall, and radial / tangential mean diameters 156 / 87 μm, density 2-7 pores/mm2. Simple perforations on tilted plates, bordered pitting, opposite-subopposite to alternate, pits hexagonal and with small apertures sometimes as horizontal slits. The length of the vascular elements is 234-406 μm. Fine spiral thickenings appear on the vessel ends. Axial parenchyma few, apotra-cheal diffuse, as short tangential uniseriate bands, and paratracheal few, as vertical strands of 4-8 cells, some-times with dark gum remains and 1-3 crystals. Medullary rays 1-3(4)-seriate, of 3-26 cells in height (i.e. 38-273 μm), and with frequency of 4-6 rays/mm tangential. Ray heterocellular with cells all procumbent, and 1-4 marginal higher or even upright. Cross fields of ray cells with ver-tical elements having sometimes small simple pits and small gum remains, often granular. Fibers polygonal in cross-section, having uneven lumina, with rare, horizontal or slightly inclined septa, and fairly thick walls of 5-8 μm double wall, with simple, rare, and very small pits on an irregular vertical row.
