Yu (Balsaminaceae), a species new to science discovered in Yunnan, China, is described and illustrated here, along with its phylogenetic position among other <i>Impatiens</i> species. Morphological, micro-morphological and molecular evidence is presented as an attestation of its novelty. <i>Impatiensyunlingensis</i> is similar to <i>I.delavayi</i> in having coarsely crenate leave margins, bracts in the upper part, ca. ⁴/₅ length of the pedicels, saccate lower sepal with shallowly bifid spur, linear capsules, and elliptic-oblong, tuberculate seeds, but differs from <i>I.delavayi</i> with lateral sepals 4 (vs. 2), lateral united petal basal lobes subtriangular (vs. dolabriform), and seeds' surface equipped with tPhytoKeys13-27https://www.ebi.ac.uk/biostudies/studies/S-EPMC9836640biostudies-literature<i>Impatiensyunlingensis</i> (Balsaminaceae), a new species from Yunnan, China.PMC9836640Gadagkar SRYu SXZhang WDXia CYYu JHQin YQin FAn MTfalse<i>Impatiensyunlingensis</i> (Balsaminaceae), a new species from Yunnan, China.<i>Impatiensyunlingensis</i> S.X.
