摘      要：Engelhardia,a genus of Juglandaceae(the walnut family),is endemic to tropical and subtropical *** rich Cenozoic fossil records and distinctive morphological characters of the living plants have been used to explore the evolutionary history and geographic distribution of ***,the taxonomy of this genus has been suffered from a lack of in-depth investigation and good specimens across its distribution *** delimitation of Engelhardia was defined with seven species in 2020,but detailed information on the circumscription of the species still remains poorly *** this study,two new species are described from Sulawesi and Borneo,Engelhardia anminiana and *** also revised and reconstructed the phylogeny within Engelhardia using morphological,molecular(plastid and ribosomal),and distribution *** sampled 787 individuals in 80 populations,and all the samples were genotyped using plastid regions,trnS-trnG,rps16,trnL-trnF,psbA-trnH,and rpl32-trnL;one ribosomal region,nuclear ribosomal internal transcribed spacer(nrITS).The all datasets were used to reconstruct the phylogenetic ***,the molecular analyses were combined for 738 sheets of specimens with 15 morphological characteristics to further explore the morphological clusters of *** analysis using morphological data confirmed the delimitation of nine Engelhardia ***,phylogenetic analysis based on molecular data(i.e.,plastid and ribosomal)supported the monophyly of Engelhardia and generated phylogenetic trees that included ***,***,***,***,***,***,***,*** and the varieties of ***(i.e.,*** ***,*** ***,*** ***,and *** ***).Our comprehensive taxonomic revision of Engelhardia will provide an insight into understanding the plant diversity in tropical and subtropical Asia.
