摘　　要：With more than 300 species,the Magnoliaceae family represents a major Magnolid lineage that is disjunctly distibuted in Asia and the New World,.The classifcation of Magnolia s.L.has been highly controversial among taxonomists,varying from one genus with several subgenera,sections,and subsections to several(up to 16)genera.We conducted a comprehensive phylogenetic study of Magnoliaceae on the basis of sequences of the complete chloroplast genomes with a broad jaxon sampling of 86 species.The phylogenetic analyses strongly support 15 major clades within Magnolia si.due to the non-monophyly of subgen.Mgnolia,the previous subgeneric treatment that recognizes three subgenera,is not supported.Based on the phylogenetic,morphological,and geographic evidence,we recognize two subfamilies in Magollaceae:Liriodendroideae and Magnolioideae,each with one genus,Liriodendron and Magnolla,respectively.Magnolla Is herein lassfed into 15 sections:sects.Mognolia,Manglietia,Micheila,willimia,Gynopodium,Kmerla,Maingola,Oyama,Rytidospermum,Splendentes,Talouma,Tulparla,Macophylla,Tllpastrum,and Yulanla.
