are relatively distinct in cross section, not very wide, the boundary marked by the presence of a terminal wood made up of mainly ground tissue. Otherwise, the structure is diffuse-porous, smaller vessels appear only in the close proximity of the terminal wood, and the rays are slightly dilated at the boundaries of the annual rings.

. The vessels have simple perforations on inclined plates. The vertical walls of vessels, especially of those vessels with lower lumen, exhibit relatively thick spiral thickenings, with repeated and obvious turns. Rounded to oval bordered pitting, relatively numerous, small of 4-7 μm, alternate to sub-opposite without touching each other, with circular apertures of 2-3.5 μm in diameter horizontally elongated or point like. The average length of the vascular elements is 500-640 μm. Inside vessels, rarely large thin walled tyloses appear.

, a few short or long uniseriate lines interleaved with fibers, constituting the terminal bands of 3-4 cells thick, which are marking the distinct boundary of the growth ring. It occurs also diffuse, as cells dispersed among the fibers within the annual ring, and also as vasicentric uniseriate. In the longitudinal sections the parenchyma consists of nearly square empty rectangular cells in vertical strands of over 8 cells, pitted and sometimes with solitary crystals.

- in cross section appear 1-3(4)- seriate, and have a special behavior: the thicker rays have continuity on 2-3 annual rings, the uniseriates have continuity only on an annual ring. Near the vessels they have a slight inflection and may come in contact with them, but generally have a linear trajectory, and the thicker ones show a slight dilation at the boundary of the growth ring. Also, the cells have a dark content. In tangential section, the uniseriates appear relatively numerous, they have 3- 12 cells in height (up to 125 μm), the ray cells round or slightly vertically elongated, mixed. The 2-4-seriates rays have 15-77 cells in height, that is, 192-500 μm and have uniseriate endings of 1-8 rounded cells, the last being narrower and elongated. The ordinary ray body cells tend to be more rounded and more equal in size (8-11 μm), and contain residual gums. Sometimes marginal, noticeably larger rounded cells (of 15-24 μm in diameter) and brighter, which appear to be mucilaginous cells. The frequency is 8-10 rays per horizontal tangential mm. Radially the rays are homocellular, formed from procumbent cells whose length varies from the early to late wood, when the cells can be squared with the same height. Ray cells have very small spaced pits of 2 μm on two rows in the early wood, or a single, larger, round or oval pit with small circular aperture, in the late wood. Sometimes, the ray cells contain large, solitary crystals.

, simple perforations, spiral thickenings frequent and relatively thick, bordered pitting, pits round to oval, numerous, alternate to sub-opposite without touching each other, small of 4-7 μm, with circular apertures of 2-3.5 μm to horizontally elongated, or point like. The vascular elements have 500-640 μm in length, large thin-walled tyloses inside and solitary crystals or colored crystal-sand. Parenchyma apotracheal diffuse, as short or long uniseriate bands interleaved in the latest wood, and rarely paratracheal. Vertically the parenchyma appears as near square empty cells in vertical strands of 2-4 cells, sometimes pitted and with crystals. Rays 1-4-seriate, the uniseriates of 3-12 cells tall, the 2-4-seriates fusiform, of 15-77 cells tall, with endings of 1-8 cells. In the ray-body sometimes larger mucillaginous cells appear. Ray frequency is of 8-10 rays on tangential mm. Rays homocellular, with ray-cells all procumbent, sometimes square, with spaced simple, very small pits, of 2 μm, on two rows arranged in the cross-fields with vessels and with solitary crystals. The fibers have polygonal section of 15-20 μm in diameter, thick walls, spiral thickenings, septa, and rare, small, simple pitting in a vertical row.
