A rare endemic plant species, Rungia mastersii, has been rediscovered in Assam after remaining unrecorded for about 180 years. The significant botanical discovery was made in the Jatinga Hills of Dima Hasao district by researchers from Assam University.
The species was originally collected by J.W. Masters in Assam in 1845. Since that first collection, no confirmed locality had been recorded for the plant, making the recent discovery an important addition to knowledge of India’s biodiversity. The new study, published in Feddes Repertorium in July 2026, provides the first confirmed locality of the species since its original collection.
Researchers documented the plant in its natural habitat and recorded details of its appearance, habitat and flowering period. Photographs of the plant and its flowers have also been provided to help future researchers identify the species.
The rediscovery highlights the importance of continued botanical surveys in biodiversity-rich regions such as Northeast India. Species that disappear from scientific records are not necessarily extinct and may survive in isolated or difficult-to-access habitats.
Scientists say further research is needed to understand the population size, distribution and conservation status of Rungia mastersii. Protecting its habitat will be important for ensuring the survival of this rare endemic species.
