- Diagnosis
- Growth ring boundaries distinct. Vessel diffuse to semiring-porous. Fibres thick-walled at growth ring boundary. Vessels arranged in no specific pattern, solitary, and radial multiples of 2–3 vessels. Mean tangential diameter of vessel lumina 50–100 µm, 20–40 vessels per mm2, vessel frequency decreasing in latewood. Axial parenchyma scanty paratracheal, diffuse, marginal, strand length 1–4 cells. Ray width 1–3 cells, 4–12 rays per mm. In
tangential section, width of oil and mucilage cell same as ray width or more. Oil and mucilage cells associated with rays and among fibres. Intervessel pits alternate and small (4–7 µm). Perforation plates simple. Shape of alternate pits polygonal or circular. All rays procumbent with very large oil
and mucilage cells, and body ray cells procumbent with 1 row (rarely 2 rows) of upright and/or square marginal cells and with very large oil and mucilage cells. Height of oil and mucilage cells 70–100 µm. Axial parenchyma common in the wood.
