Original protologue

Wood diffuse–porous. Growth rings absent. Vessels small to medium, tangential diameter range 70–184 μm, mean 126 μm, solitary as well as in radial multiples of 2–5, sometimes in tangential pairs, irregularly distributed, 5–7 per sq mm, round to oval, tylosed; vessel–members range 90–270 μm, with oblique to horizontal ends, mean 170 μm; perforations simple; intervessel pits bordered, alternate, oval, small, about 4 to 5 μm in diameter with linear–lenticular apertures. Axial parenchyma apotracheal, diffuse to diffuse–in–aggregate in the form of predominantly uniseriate, irregular, tangential lines; cells 40–50 μm in length and 15–25 μm in width. Rays 1 to 2 seriate, predominantly uniseriate, biseriate rays made up of procumbent cells in the middle portion with upright or square cells at the ends, 6–11 per mm, 14–18 μm in width and 3–10 cells or 81–259 μm in height; crystals observed in ray cells. Fibres thick–walled and non–septate having bordered pits of 2–4 μm.
