Toona

ToonaSinensis

Toona, also known as Cedrela, is a genus of deciduous trees in the Meliaceae family, native to eastern and southeastern Asia, and the western Pacific Ocean islands. The genus comprises several species, with Toona sinensis being the most widely recognized. These trees are valued for their timber, ornamental qualities, and in some cases, culinary uses. The wood of Toona species is known for its durability, attractive grain, and resistance to termites, making it a preferred material for furniture, construction, and musical instruments.

Description

Toona trees can grow up to 30-40 meters in height, with a straight trunk and a broad, spreading canopy. The leaves are pinnate, with 10-40 leaflets, each leaflet being lanceolate to ovate in shape. The trees produce small, fragrant flowers that are white to pale pink, arranged in large terminal panicles. These are followed by fruit in the form of capsules that release winged seeds, facilitating wind dispersal.

Distribution and Habitat

The natural range of Toona extends from Afghanistan across the Himalayas, through China, to Australia and the western Pacific. These trees are adaptable to a variety of soil types but prefer moist, well-drained soils. They are found in both mixed and pure forests, from sea level up to altitudes of about 2000 meters.

Species

Some notable species within the Toona genus include:

• Toona sinensis (Chinese mahogany or Chinese cedar) - Widely cultivated for its edible young leaves and shoots, which are used in various Asian cuisines.
• Toona ciliata - Known for its high-quality timber, used in furniture making and interior finishing.
• Toona sureni - Found in Southeast Asia, its wood is also highly valued for construction and furniture.

Uses
