Archidendron bigeminum is a tree species in the legume family (Fabaceae). It is found in India and Sri Lanka. It is known as "Kalitiya - කලටිය" in Sinhala people. The World Conservation Monitoring Centre (WCMC) in the 1998 IUCN Redlist reviewed Abarema bigemina and Pithecellobium gracile as Vulnerable species. These are nowadays both considered junior synonyms of Archidendron bigeminum. It may be that the Indian population consists of a smaller-growing variety than that on Sri Lanka.
