Sapindus trifoliatus, commonly known as the South India soapnut or three-leaf soapberry, is a medium to large deciduous tree that can grow up to 25 meters tall. It has a dense, broad crown and compound leaves that are 30-50 cm long, with 5-10 pairs of leaflets. The flowers are small, greenish-white, and polygamous, appearing in axillary or terminal panicles, while the fruit is a globose drupe, about 1.8-2.5 cm across, turning from greenish-yellow to dark brown as it ripens. Native to the Indian subcontinent, including Pakistan, India, Bangladesh, the Andaman Islands, Myanmar, and Sri Lanka, the tree thrives in seasonally dry tropical biomes and is commonly found in deciduous forests from plains to elevations of up to 750 meters.
The South India soapnut’s ecological significance extends beyond its physical characteristics, as it provides a valuable food source for various wildlife species, including bees and other pollinators. Its flowers attract bees and other pollinators, contributing to its success in its native habitats.
