A scientific expedition in Arunachal Pradesh has uncovered a previously undocumented botanical species, highlighting the dense floral wealth of the northeastern frontier. The newly identified flora belongs to the Begonia genus and was located within Keyi Panyor district. Named Begonia neelamorum, the detailed scientific findings detailing this discovery have been officially published in the peer-reviewed international botanical journal Taiwania, following confirmation by officials on Friday.
Honouring Local Support and Indigenous Heritage
The discovery was spearheaded by a four-member investigative team comprising Dipankar Borah, Madhusudhan Khanal, Momang Taram, and Neelam Gap. Field researchers designated the specific epithet neelamorum as a tribute to the Neelam clan of the indigenous Nyishi community, recognizing their vital logistical assistance and navigation guidance across difficult terrain during the expedition. Among local inhabitants, the plant has long been known in indigenous parlance as 'kobiirhopu baabrai'.
Distinctive Morphology and River-Cliff Habitat
According to the published study, the botanists observed this petite tuberous plant thriving exclusively on steep, moisture-laden rock faces running alongside the Keyi River, situated at an elevation of approximately 1,000 metres. The plant is characterized by a single, sessile, light-green leaf and develops distinct white male as well as female blossoms. While visually reminiscent of Begonia prolifera, taxonomic evaluation revealed crucial differentiating markers: glandular hairs, a distinctly rounded stem, ovate leaves bearing double-serrated margins, an altered inflorescence architecture, and noticeably shorter styles.
Distribution Limits and Global Context
Field records indicate that the plant's currently known wild occurrence is restricted to an isolated pocket of roughly three square kilometres inside Keyi Panyor. Under the formal evaluation rubrics established by the International Union for Conservation of Nature (IUCN), Begonia neelamorum has been provisionally designated under the 'Data Deficient' category due to a lack of comprehensive population metrics. This addition elevates the count of documented Begonia species across Northeast India to 54. Globally, the overarching Begonia genus encompasses around 2,200 recognized species, dispersed predominantly throughout tropical and subtropical habitats.
