Pyrus zhaoxuanii (Rosaceae), A new pear species from Danxiashan Mountain, Guangdong, China

<i>Pyruszhaoxuanii</i> is described as a new species from Guangdong Province, China, within the genus <i>Pyrus</i>, specifically under P.subg.Pashia. Although it shares morphological similarities with <i>P.calleryana</i>, <i>P.zhaoxuanii</i> 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 <i>P.zhaoxuanii</i> forms an independent branch within <i>Pyrus</i> 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.
