- Diagnosis
- Growth rings distinct to indistinct, wood diffuse porous. Vessels solitary
and in short radial multiples, mean tangential diameter 50–100 μm, intervessel and vessel-ray parenchyma pits bordered, alternate. Fibers mostly non-septate and with occasional septae, dimorphic with parenchyma-like fibers in irregular bands. Axial parenchyma scanty paratracheal. Rays uniseriate, rarely biseriate or with short biseriate portions, of all upright cells or including some procumbent and weakly procumbent cells.
