Abstract
Pyruszhaoxuanii is described as a new species from Guangdong Province, China, within the genus Pyrus, specifically under P.subg.Pashia. Although it shares morphological similarities with P.calleryana, P.zhaoxuanii can be distinguished by its uniquely small, obovate, leathery leaves, which have an obtuse apex and short petioles. A phylogenetic analysis based on single nucleotide polymorphisms (SNPs) indicated that P.zhaoxuanii forms an independent branch within Pyrus and is categorized in the Oriental clade, P.subg.Pashia. Currently, this species has only been recorded in the Danxiashan National Nature Reserve. Considering its potential distribution and population size, we recommend classifying this species as Least Concern (LC) according to the IUCN Red List classifications and criteria.
