- Diagnosis
- Wood diffuse–porous. Growth rings absent. Vessels mostly small to sometimes very small in size, tangential diameter range 35–77 μm, mean 58 μm, almost exclusively solitary, rarely in radial pairs, evenly distributed, 25–35 per sq mm, usually round to oval, tylosed; vessel members range 65–270 μm, mean 158 μm, with transverse to oblique ends; perforations simple; vasicentric tracheids present forming a thin sheath around most of the vessels, tracheidal pits in 1 or 2 rows and 3 to 4 μm in size. Axial parenchyma both paratracheal and apotracheal, paratracheal scanty and intermingled with tracheids, apotracheal diffuse to diffuse–in–aggregate; parenchyma cells thin–walled, 39–107 μm in length and 11–19 μm in width; crystals present in parenchyma cells. Rays closely spaced, 16–22 per mm, 1–2 seriate, heterocellular, made up of procumbent cells in the middle portion with 1–2 rows of upright cells at the end of the rays; ray cells 11–14 μm in tangential height. Fibres thick–walled and non–septate.
