Basic Description: Samanea saman is a large, deciduous tree that can reach heights of 15–25 meters, with a canopy diameter extending up to 30 meters. It features a broad, umbrella-shaped crown, providing extensive shade. The leaves are bipinnate, comprising 6–16 pairs of leaflets, each measuring 2–4 cm in length and 1–2 cm in width. The tree produces pinkish flowers with white and red stamens, arranged in loose, umbelliform heads containing 20–25 flowers. The fruit is a broadly linear, compressed, indehiscent pod, 10–22 cm long, containing a sweet, pulpy mesocarp and 5–20 ellipsoid seeds.

Distribution and Habitat: Native to Central and South America, Samanea saman has been widely introduced to tropical regions worldwide, including West Africa. In Nigeria, it is commonly planted as an ornamental and shade tree in urban areas, parks, and along roadsides. The species thrives in a range of habitats, from dry lowland grasslands to moist, evergreen woodlands, and is adaptable to various soil types, including those that are infertile or waterlogged. It prefers full sun and can tolerate mean annual rainfall between 600–3,000 mm.

Medicinal Properties: Various parts of Samanea saman are utilized in traditional medicine:

  • Roots: In Venezuela, the roots are used against stomach cancer.
  • Leaves and Bark: Employed in folk remedies for ailments such as colds, diarrhea, headaches, and stomachaches.
  • Pods: The sweet pulp is consumed for its laxative properties and is also used to treat bronchitis and coughs.

Known Toxicity: There are no widely documented toxic effects associated with Samanea saman. However, as with many plants, it is advisable to exercise caution and consult local knowledge before utilizing any part of the tree for medicinal purposes.

Additional Information:

  • Ecological Impact: While valued for its shade and ornamental appeal, Samanea saman has become invasive in certain regions, such as Fiji, where it can dominate vegetation and invade native forest ecosystems.
  • Wood Utilization: The wood is used for various purposes, including furniture, carvings, and construction. It is known for its durability and resistance to termites.
  • Cultural Significance: The tree is often planted in public spaces for its aesthetic value and the extensive shade it provides, making it a popular choice in tropical urban planning.
