Aim: The study aims to better understand plant diversity in the border areas of Yunnan. These border areas have relatively intact forest ecosystems but are poorly explored.

Methods: In this study, plants were collected and photographed through intensive field investigation, made into specimens, sorted and identified. The voucher specimens for each recorded species were deposited in the Herbarium of Xishuangbanna Tropical Botanical Garden of Chinese Academy of Sciences (HITBC), Herbarium of Institute of Botany of Chinese Academy of Sciences (PE), Herbarium of Kunming Institute of Botany of Chinese Academy of Sciences (KUN) and Herbarium of Xiamen University (AU).

Results: One new record family, namely Aptandraceae (Anacolosa griffithii), two new record genera, namely Pottingeria (P. acuminata), Cordisepalum (C. phalanthopetalum), thirty new record species, namely Phlogacanthus gomezii, Staurogyne shanica, Hydnocarpus macrocarpus, Alphonsea ventricosa, Huberantha jenkinsii, Miliusa chantaburiana, M. dioeca, Impatiens andersonii, Garcinia lanceifolia, Dillenia parviflora, Parashorea buchananii, Castanopsis birmanica, Heritiera burmensis, Phrynium pubinerve, Bulbophyllum obrienianum, B. sinhoense, Dendrobium dantaniense, D. parcum, Epipactis flava, Eulophia macrobulbon, Micropera mannii, Vanilla borneensis, Phyllanthus discofractus, P. mirabilis, Maesa tomentella, Sabia wardii, Ailanthus integrifolia subsp. calycina, Wikstroemia floribunda, Hedychium gardnerianum, Monolophus linearis, were reported for the flora of China.

Conclusion: The border area of Yunnan possesses one of the richest floras in China, but the floristic survey in this area is still inadequate. Therefore, intensive floristic surveys are needed to be strengthened in the future to obtain reliable information on the flora of the border areas of Yunnan.
