Six new additions for the flora of Assam and Arunachal Pradesh (India)

The Eastern Himalaya, particularly Assam and Arunachal Pradesh, represents a globally significant hotspot of plant diversity characterized by high species richness and endemism. Field surveys conducted between 2022 and 2025 resulted in the documentation of six new distributional records, including four from Assam and two from Arunachal Pradesh, belonging to the families Begoniaceae, Rubiaceae, Piperaceae, and Gesneriaceae. Specimens were collected, photographed, and processed using standard herbarium methods and deposited in ARUN and TOSEHIM. Taxonomic identifications were confirmed through critical comparison with relevant literature, herbarium specimens, and online databases. These new records enhance the floristic understanding of the Eastern Himalaya and underscore the region’s significance for future biodiversity exploration and conservation efforts.
