ABSTRACT The present study confirms the occurrence of Impatiens lhunzeensis J. Tian, G.W. Hu & Q.F. Wang in Arunachal Pradesh and Nagaland, India, marking its first record outside its type locality in southeastern Xizang (Tibet), China. This significant range extension highlights the floristic affinity between India's Eastern Himalaya and adjoining regions representing the westernmost extension of the Indo‐Malayan humid forest. This species is distinguished by several key morphological traits including a densely hairy apical stem region, coriaceous leaves with a reddish pink abaxial surface bearing hairs along the veins, and other key diagnostic features. To facilitate identification, we provide a detailed morphological account and photographic documentation. This finding not only enriches the floristic diversity of northeastern India but also emphasizes the importance of continued botanical explorations in remote and unexplored areas, contributing to broader taxonomic knowledge conservation efforts in this biodiversity‐rich region.
