Meliaceae Plant Family

About the Meliaceae or Mahogany Family

Meliaceae is a family of flowering trees and shrubs, found in tropical and subtropical regions worldwide. The family includes approximately 600 species, distributed across 50 genera. Meliaceae is known for its many uses, including medicinal and industrial applications. Many species in the family are valued for their durable timber, which is used for furniture, construction, and carving. The family also includes several plants with medicinal properties, particularly in traditional and alternative medicine. Meliaceae has been used for centuries by indigenous cultures to treat a wide range of ailments, from fevers and infections to skin conditions and gastrointestinal disorders.

Taxonomy and Classification

Meliaceae is classified within the order Sapindales, which also includes the soapberry family (Sapindaceae) and the cashew family (Anacardiaceae). Within Meliaceae, there are three subfamilies: Cedreloideae, Melioideae, and Swietenioideae. The family includes approximately 50 genera, including Azadirachta (neem), Swietenia (mahogany), and Trichilia. Meliaceae is characterized by its alternate leaves, often pinnate or bipinnate, and its distinctive inflorescences, which are composed of many small flowers arranged in racemes or panicles. The flowers have five petals and five sepals, and are often fragrant. Many species in the family produce fleshy fruit, with a hard outer layer and edible pulp.

Morphology and Characteristics

Meliaceae is a family of trees and shrubs with a diverse range of morphological features. Most species have alternate, pinnate or bipinnate leaves, which are often large and glossy. The flowers are typically small and fragrant, with five petals and five sepals. The inflorescences are composed of many small flowers arranged in racemes or panicles. The fruit of Meliaceae is a drupe, with a hard outer layer and fleshy pulp inside. Many species in the family produce valuable timber, with dense and hard wood that is resistant to rot and insect damage. Some species also have medicinal properties, particularly in traditional medicine, and have been used for centuries to treat a wide range of ailments.

Distribution and Habitat

Meliaceae is a family of flowering trees and shrubs found in tropical and subtropical regions around the world. The family is particularly diverse in South America, Africa, and Southeast Asia, but can also be found in parts of Australia, India, and the Caribbean. Many species in the family are adapted to warm and humid environments, and thrive in rainforests, savannas, and other tropical habitats. However, some species are able to grow in more temperate climates and can be found in drier habitats such as woodlands and scrublands. The distribution of Meliaceae is influenced by environmental factors such as temperature, precipitation, and soil type, with different species exhibiting varying degrees of tolerance for these conditions.

Economic and Ecological Importance

Meliaceae is a family of great economic and ecological importance. Many species in the family are valued for their durable timber, which is used for furniture, construction, and carving. The wood of some Meliaceae species, such as Swietenia mahagoni (West Indian mahogany) and Khaya senegalensis (African mahogany), is particularly prized for its attractive grain patterns and resistance to rot. Several plants in the family also have medicinal properties and are used in traditional medicine to treat a variety of ailments. For example, neem (Azadirachta indica) has been used for centuries as an antiseptic and insecticide, while Melia azedarach has been traditionally used to treat fever and skin conditions. Ecologically, Meliaceae is important for its role in forest ecosystems, providing habitat and food sources for a variety of animals. The family also contributes to overall biodiversity and plays a key role in ecosystem functioning.

Notable Species
