Genus of flowering plants in the family Fabaceae

Peltogyne, commonly known as purpleheart, violet wood, amaranth and other local names (often referencing the colour of the wood) is a genus of 23 species of flowering plants in the family Fabaceae; native to tropical rainforests of Central and South America; from Guerrero, Mexico, through Central America, and as far as south-eastern Brazil.[2] They are medium-sized to large trees growing to 30–50 m (100–160 ft) tall, with trunk diameters of up to 1.5 m (5 ft). The leaves are alternate, divided into a symmetrical pair of large leaflets 5–10 cm (2–4 in) long and 2–4 cm (1–2 in) broad. The flowers are small, with five white petals, produced in panicles. The fruit is a pod containing a single seed. The timber is desirable, but difficult to work.

Distribution [ edit ]

The species of the genus range from southeastern Brazil through northern South America, Panama, Costa Rica, and Trinidad, with the majority of species in the Amazon Basin. P. mexicana is a geographic outlier, native to the Mexican state of Guerrero.[2] Overharvesting has caused several species to become endangered in areas where they were once abundant.[3]

Wood [ edit ]

The trees are prized for their beautiful heartwood which, when cut, quickly turns from a light brown to a rich purple color. Exposure to ultraviolet (UV) light darkens the wood to a brown color with a slight hue of the original purple.[4] This effect can be minimized with a finish containing a UV inhibitor. The dry timber is very hard, stiff, and dense with a specific gravity of 0.86 (860 kg/m3 or 54 lb/cu ft). Purpleheart is correspondingly difficult to work with.[5] It is very durable and water-resistant.

Uses and hazards [ edit ]

Purpleheart is prized for use in fine inlay work especially on musical instruments, guitar fret boards (although rarely), woodturning, cabinetry, flooring, and furniture. It is also used in many hobby woodworking projects, such as bottle stoppers, pens, bowls, knife scales, and jewelry boxes.[6] The timber is also valuable in applications that require toughness, such as truck decking.[7] Purpleheart presents a number of challenges in the woodshop. Its hard-to-detect interlocking grain makes hand-planing, chiseling and working with carving tools a challenge. However, woodturners can note that with sharp tools, it turns clean, and sands well.[6] Exposure to the dust generated by cutting and sanding purpleheart can cause skin, eye, and respiratory irritation and nausea,[6] possibly because of the presence of dalbergione (neoflavonoid) compounds in the wood. This also makes purpleheart wood unsuitable to most people for use in jewelry.[8] Purpleheart is also a fairly expensive wood, which is why it is usually used in smaller-scale projects.[9]

Species [ edit ]

The following list of species is according to Plants of the World Online.[10]

What is the mango wood?

Mango wood is categorised as a hardwood, due to its dense grains. This means it is a strong and durable wood making it perfect for furniture. Due to the density of the wood, it doesn't wear out easily and can keep its high lustre texture for many years.

grainandframe.com - Mango Wood - What is it and what are the benefits of Mango wood furniture?

Mango wood is originally derived from the Mango tree; the tree that produces the sweet, fleshy fruit known as a Mango. The Mango tree belongs to the Anacardiaceae family, which also includes Pistachio, Cashew and Poison Ivy trees. The tree is “evergreen” meaning it has a foliage that remains green and functional through more than one growing season. Mango trees typically reach an average height of between 15 and 18 metres (50ft and 60ft). Mango wood is categorised as a hardwood, due to its dense grains. This means it is a strong and durable wood making it perfect for furniture. Due to the density of the wood, it doesn’t wear out easily and can keep its high lustre texture for many years. However, unlike other hardwood furniture, Mango wood is often seen as more affordable and sustainable.
