Some trees have very special wood.
These trees grow in warm lands. They can be small shrubs or big trees.
Many of these trees are called rosewoods. They smell sweet when they are cut.
People use the wood for fine furniture. It is also used for music tools. Some wood is very dark and black. This wood is good for making instruments. These trees are very important to protect.
Dalbergia is a large group of plants. It includes small trees, shrubs, and vines.
These plants grow in warm, tropical places. You can find them in Africa, Asia, and the Americas.
Many Dalbergia trees are famous for their wood. This wood is often very pretty. It can have many colors and patterns.
Some people call these rosewoods. They get this name because they smell sweet when cut. This smell comes from oils inside the wood.
People use this wood for many things. It is great for making fine furniture. It is also used to make musical instruments.
For example, African blackwood is very dark. It is used to make woodwind instruments.
Some parts of the plant help animals. Larvae of certain moths eat Dalbergia leaves.
However, the wood can cause skin allergies in some people. Because these trees are so special, they are protected. Laws help make sure they do not disappear.
Dalbergia is a large group of many different plants. It includes small trees, medium trees, shrubs, and climbing vines called lianas.
These plants belong to the pea family, known as Fabaceae. Most of them live in warm, tropical parts of the world. You can find them in Central and South America. They also grow in Africa, Madagascar, and Southern Asia.
Many people value these plants for their beautiful wood. Many species are known as rosewoods. This name comes from the sweet smell of the timber when it is cut.
The wood contains aromatic oils that create this scent. Some woods have very pretty colors and grains. For example, Brazilian tulipwood is cream-colored with red or salmon stripes. Another type, kingwood, is purple with dark stripes.
Scientists have found evidence that these plants are very old. Fossil seed pods have been found in many different places. A fossil called Dalbergia phleboptera was found in France. Other fossils, like Dalbergia nostratum, were found in Southern Slovakia.
In China, fossils of Dalbergia lucida were found in the Xiaolongtan Formation. These fossils show that Dalbergia has been around for a long time. They help us understand how the plants changed over many years.
Different species are used for many special jobs. African blackwood is a very dark wood used for woodwind instruments.
In northern India, Dalbergia sissoo is used for furniture and railway sleepers. This wood is very strong and tough. It has a density of 770 kg/m3. Some species are also used as food for tiny living things. The larvae of certain moths, called Lepidoptera, eat the leaves. One type, Bucculatrix mendax, eats only Dalbergia sissoo.
We must be careful with these plants today. Some Dalbergia wood can cause skin allergies in people. This happens because of special substances called quinones in the wood.
Because they are so important, many species are protected. They are listed under a rule called CITES. This rule helps protect animals and plants in international trade. Most species are on Appendix II of this list. One special tree, Dalbergia nigra, is on the even stricter Appendix I list.
Dalbergia is a large genus of plants within the Fabaceae family. This family is commonly known as the pea family. The genus includes a wide variety of growth forms. You can find small to medium-sized trees and shrubs. It also includes lianas, which are woody climbing vines.
Scientists have placed these plants into an informal group called the Dalbergieae clade. This genus has a very wide natural distribution. Most species are native to tropical regions. These regions include Central and South America, Africa, Madagascar, and Southern Asia.
Many species in this genus are highly valued for their timber. They are often prized for decorative and fragrant wood. This fragrance comes from rich, aromatic oils found in the timber. Many of these species are called rosewoods. This name describes the sweet smell the wood releases when it is cut.
Some species are specifically known for their unique colors and grain patterns. For example, Dalbergia decipularis produces Brazilian tulipwood. This wood is cream-colored with red or salmon stripes. It is often used for veneers or crossbanding.
Other species offer different colors and uses for craftsmen. Dalbergia cearensis yields kingwood, which is purple with dark stripes. In Central America, Dalbergia retusa produces cocobolo. This wood shows a spectacular orange-red figure when freshly cut. This color slowly fades into more subdued tones when exposed to air.
Another important timber is African blackwood, or Dalbergia melanoxylon. This wood is intensely black. Because of its color, it is in high demand for making woodwind musical instruments.
Dalbergia sissoo is a very significant species in northern India. It has historically been the primary rosewood species in that region. This wood is exceptionally strong, tough, and durable. It has a density of 770 kg/m3. The wood ranges in color from golden to dark brown. It maintains its shape well and can be easily seasoned. While it is difficult to work, it takes a fine polish.
People use it for high-quality furniture, plywood, and even railway sleepers. It is also used for sporting goods and decorative carvings.
The history of Dalbergia is visible through the fossil record. This shows the genus has existed for millions of years. Fossil seed pods of Dalbergia phleboptera were found in a Chattian deposit in France. In Southern Slovakia, fossils of Dalbergia nostratum were found in rhyodacite tuff. These fossils date back to the Lower Miocene age.
In Hungary, fossil seed pods of Dalbergia mecsekense were found in a Sarmatian deposit. Additionally, Dalbergia lucida fossils were described from the Xiaolongtan Formation in China. These fossils date to the late Miocene age.
While humans use these plants, they also support local ecosystems. Some species serve as food plants for the larvae of Lepidoptera, which are moths. For instance, the moth Bucculatrix mendax feeds exclusively on Dalbergia sissoo. However, some species can be difficult for humans to handle. Dalbergia species are notorious for causing allergic reactions. This happens because the wood contains sensitizing quinones. These chemical substances can trigger sensitivities in people.
Because of their value, many Dalbergia species face conservation challenges. They are all protected under CITES. This is the Convention on International Trade in Endangered Species of Wild Fauna and Flora. This international agreement regulates how these plants are traded. Most Dalbergia species are listed in Appendix II of CITES. However, Dalbergia nigra is listed in the stricter Appendix I. This higher level of protection is necessary to ensure their survival.
