A rare plant species native to Arunachal Pradesh has been rediscovered after nearly 189 years during a botanical survey in Lohit district. The species, identified as Henckelia monophylla, had not been recorded since the early 19th century. Its reappearance is for plant taxonomy, biodiversity mapping and conservation planning in the Eastern Himalayas.
Rediscovery in Lohit District
The plant was located by scientists from the Botanical Survey of India during field exploration in Lohit district. The rediscovery confirms that the species still survives in the wild after a long gap in scientific records. Such findings are important for updating floristic inventories and understanding the distribution of endemic species.
Botanical Features of the Species
Henckelia monophylla belongs to the Gesneriaceae family. It is a perennial herb usually found in moist, forested habitats. Plants of the Henckelia genus generally have upright or slightly trailing stems and simple leaves that are ovate or lance-shaped. They produce axillary inflorescences with one or more tubular or funnel-shaped flowers. Their fruits are elongated capsules containing many tiny seeds.
Ecological Significance
Arunachal Pradesh is one of India’s richest biodiversity hotspots. The rediscovery underlines the importance of continued botanical surveys in remote and underexplored areas. It also marks the need to conserve forest habitats that support rare and endemic flora. Such species can be vulnerable to habitat loss, climate change and limited ecological data.
Scientific and Conservation Value
The finding adds to global botanical knowledge and strengthens the case for field-based documentation in the Eastern Himalayas. It also supports conservation efforts aimed at protecting endemic plant diversity. The rediscovery has been welcomed as a notable scientific achievement and a reminder of the ecological value of Arunachal Pradesh’s forests.
