Abstract

A floristic survey conducted in July 2024 in Aizawl district of Mizoram, led to the collection of unidentified species of Hydrocotyle. Detailed morphological examination, comparison with taxonomic literature and consultation of herbarium specimens confirmed its identity as Hydrocotyle bonariensis Lam. This is first specimen based, taxonomically confirmed record of H. bonariensis from India. This species is a perennial prostate herb widely distributed throughout the tropical and sub-tropical regions. It is well adapted to sandy, moist habitats including coastal dunes, estuaries, and ponds. Herbarium specimens were prepared following standard taxonomic procedures and submitted at the Botanical Survey of India, Eastern Regional Centre, Shillong. Morphological characters, habitat and specimen details are provided to facilitate accurate identification. This discovery highlights the floristic richness of northeast India and reinforces the importance of systematic botanical surveys in underexplored habitats.
