Paraserianthes

Paraserianthes is a genus of flowering plants in the family Fabaceae, native to the Indo-Pacific region. It was formerly included in the genus Albizia. The genus is characterized by its feathery, bipinnately compound leaves and showy, often fragrant, flower heads that resemble those of Albizia. These flowers typically have numerous stamens that give them a puffball appearance.

Species within Paraserianthes are mostly trees and shrubs. They are known for their rapid growth and adaptability to various environmental conditions, often thriving in disturbed or open habitats. Many species are nitrogen-fixing, contributing to soil fertility. The wood of some Paraserianthes species is used for timber, while others are cultivated for ornamental purposes due to their attractive flowers and foliage.

The distribution of Paraserianthes extends across Southeast Asia, Australia, and the Pacific Islands. Several species have become naturalized in other parts of the world. For example, Paraserianthes lophantha, commonly known as Crested Wattle or Albizia, is widespread in Australia and has been introduced to many other countries.

Reproduction in Paraserianthes is typically through seeds, which are often contained in pods. Pollination is usually carried out by insects, attracted by the abundant nectar and showy flowers. The genus represents a significant component of tropical and subtropical flora, with ecological and economic importance in its native ranges.
