The genus name "Albizia" honors Filippo degli Albizzi, an Italian nobleman who introduced the genus to Europe in the 18th century. The species name "Lebbeck" is derived from the Arabic name for the plant.

Morphology:

Siras is a medium-sized deciduous tree that can grow up to 30 meters in height. The tree has a straight trunk with a smooth gray bark. The leaves are compound, dark green, and feathery in appearance, measuring up to 15 cm in length. The leaflets are small and numerous, with up to 30 pairs on each leaf. The leaves of Siras are bipinnate, meaning that each leaflet is further divided into smaller leaflets.

Siras produces fragrant, white to pale yellow flowers that bloom in clusters. The flowers are bisexual, and each has five petals and numerous stamens. The flowers are about 2-3 cm in diameter and bloom during the summer months. The fruits of Siras are flat, brown pods that are about 20-30 cm in length and 3-5 cm in width. Each pod contains several seeds, which are oval in shape and about 1 cm in length.

Siras has a distinctive appearance due to its feathery compound leaves and fragrant flowers that bloom in clusters. Its flat, brown pods and oval seeds are also characteristic of the species.
