Guwahati: In a significant botanical finding from Northeast India, researchers have recorded a rare flowering plant species, Agapetes wardii, in Arunachal Pradesh’s Changlang district, marking its first-ever documented presence in India.
The discovery, published in the journal Feddes Repertorium, was made by a team of scientists including Vinay Kumar Sahani and Minom Pertin from the Society for Education and Environmental Development (SEED), Arunachal Pradesh, Lemmem Gammi from Rajiv Gandhi University, and Dipanwita Banik from CSIR–North East Institute of Science and Technology (NEIST), Jorhat.
The species, an epiphytic shrub known for its striking red to pinkish flowers, was identified during field surveys in the forested landscapes of Changlang—part of the Indo-Myanmar biodiversity hotspot, one of the richest yet least explored ecological regions in the world.
While Agapetes wardii is known from neighbouring regions such as Myanmar, this is the first confirmed record of the species within the Indian territory. Its presence in Changlang expands the known geographical distribution of the species and adds to the growing list of botanical discoveries from Arunachal Pradesh.
Belonging to a genus that includes over 100 species across Asia, Agapetes plants are typically found in humid, forested environments, often growing as epiphytes—plants that live on other plants without drawing nutrients from them.
Researchers note that Agapetes wardii can be distinguished from closely related species by its elliptic to lance-shaped leaves with pointed tips, unique floral structure, including distinctive anthers and slender filaments longer than the anthers.
These features set it apart from similar species such as Agapetes hosseana and Agapetes buxifolia.
Beyond the addition of a new species record, the finding underscores a larger scientific reality: vast stretches of Northeast India, particularly Arunachal Pradesh, remain underexplored.
Changlang district, with its dense tropical and subtropical forests, continues to emerge as a hotspot for new and rare species discoveries. Scientists say such findings are critical for understanding plant diversity and evolution, strengthening conservation planning and documenting species before habitats face increasing pressure from climate change and human activity.
The discovery of Agapetes wardii reinforces the Eastern Himalaya’s reputation as a global biodiversity treasure trove, where even well-known plant groups continue to yield surprises.
For researchers, it is also a reminder that many species may already exist within India’s borders, but remain undocumented due to limited scientific exploration.
As botanical surveys continue across Arunachal’s remote landscapes, scientists believe more such discoveries are only a matter of time.
