I. kamtilongensis can be distinguished from its closest ally I. finetii by its hairy white stem, yellow flowers having 2 red blotches, bigger sepals and glabrous capsule. The specimens are deposited in the Herbarium of the Institute of Ecology and Biological Resources (HN) Ha Noi, Vietnam. Morphological redescription and illustrations are provided along with notes on distribution, ecology, phenology and conservation of the species. Keywords: Balsaminaceae, Impatiens, I. kamtilongensis new record, Vietnam. INTRODUCTION The genus Impatiens, comprising approximately 900 species is distributed in tropical to subtropical Asia and Africa while very few species occur in temperate Asia, Europe and North America. In Vietnam, this genus comprises 34 species [11, 33]. During a recent fieldwork in Xuan Lien Nature Reserve, Northern Vietnam, the first and third author collected and found I. kamtilongensis. Morphologically, I. kamtilongensis is close to I. finetii but it can be distinguished from the later by its hairy white stem and yellow flowers with 2 red blotches. MATERIALS AND METHODS All specimens deposited in various herbaria of Vietnam namely HN, VNM, HNU, NHNPI along with two Chinese herbaria, viz. KUN & SCBG were studied. Specimens in the virtual herbaria, such as PE, K & P were also studied. The collected specimens of I. kamtilongensis were thoroughly processed using standard preservation .
