Anatomical features of wood – Pore arrangement. A - Ring porous with pores solitary and in short radial multiples. B- Diffused porous with pores solitary in short radial multiples. C- tangential clusters. D- Exclusively solitary. E- Long radial multiples. F- Flame like and diffused porous. G- Oblique groups. H – Flame like and ring porous.

Anatomical features of wood: Parenchyma distribution. A-Diffuse or scattered. B- Diffuse in aggregates or fine lines. C – Delimeting growth rings. D- Vasicentric. E- Aliform. F- Confluent- narrow. G- Confluent-broad. H- Banded-broad. I- Banded- narrow

Anatomical features of wood: A- Tyloses in vessels. B- Coloured deposits in vessels. C- Ripple marks. D- Intercellular canals in long tangential bands. E- Intercellular canals in short tangential groups. F- Radial Intercellular canals in rays. G- Broad and fine rays as seen on tangential surface. H- Broad and fine rays as seen on end surface. I- silver grain due to ray flecks. G- Included phloem. K- Included phloem
