Department name:
Leguminosae (Caesalpinoideae)
Genus name:

Trees and distribution:
Distribution or main origin: Iron sword wood is mainly produced in tropical Asia, such as India, Sri Lanka, Myanmar, Thailand, Vietnam and other countries. my country's Yunnan, Guangdong, Guangxi and other places also have a small amount of production.
Construction Features:
The difference between heartwood and sapwood is obvious, the sapwood is slightly wider, yellowish-white; the heartwood is brown to dark brown, and black stripes are common. The main single hole and 2-3 radial multiple holes. The paratubular axial parenchyma is wing-like or short-winged, and its width is wavy, as light-colored thin stripes, which are obvious to the naked eye and have chain-like crystals. Wood ray homotype, 2-3 cells wide. The pits between the rays and the vessels are roughly the same as the pits between the vessels.
Tree properties:
The growth turn is not obvious. Therefore, the porous material has medium pore size, slightly less, uniform distribution, single pore, a few multiple pore, containing black gum, sediment or intrusion. Axial parenchyma is abundant, fascicular, wing-like, and broad-banded near the tube, concentrically wavy, and its width is almost equal to that of mechanical tissue bands. Wood rays are thin to very thin and dense; streaks can be seen on the surface; no ripple marks on the string surface. The wood has weak luster, no special smell and taste; the texture is straight or slightly staggered, and the structure is slightly rough. Corrosion resistance, strong durability. The material is hard and heavy, with high strength and an air-dry density of 0.75-0.88g/CM3.
Tree use:
Blockboard, marquetry, handles, pillars and trim (e.g. sliced veneer)
Identification points:
The difference between heartwood and sapwood is obvious, the sapwood is slightly wider, yellowish-white; the heartwood is brown to dark brown, and black stripes are common.
