本文讨论了Altingiaceae三个属的系统发育关系，本文以苹果树属、枫香属和半枫香属植物为材料，根据cpDNA的matK序列、psaA和ycf 3基因间的间隔区（PY-IGS）和nrDNA的内转录间隔区（ITS），对苹果树属、枫香属和半枫香属植物进行了研究。以金缕梅科（Hamamelidaceae）金缕梅属（Hamamelisjaponica）和米老排属（Mytilarialaosensis）、连香树科（Cercidiphyllumjaponicum）连香树属（Cercidiphyllaceae）连香树属（Cercidiphyllumjaponicum）和虎皮楠科（Daphniphyllumcalycinum）虎皮楠属（Daphniphyllumcalycinum）为外类群，基于matK、PY-IGS和ITS 3个数据集构建系统发育树。分配同质性检验表明，三个数据集和合并数据是同质的。一个综合分析也产生了一个强有力的支持genetic。系统发育树显示，北美和西亚种、L.苏合香和L. orientalis分别形成一个单系群，该群是包括该科中所有亚洲物种的分支的姐妹群。枫香属与Altingia和Semiliquidambar并系。系统发育分析的分子数据表明，在Altingiaceae的属划分的分类重新审查是必要的。
Phylogenetic relationships of the three genera of the family Altingiaceae, i.e.,Altingia,LiquidambarandSemiliquidambar, based onmatK sequences and the intergenic spacer between thepsaA andycf3 genes (PY-IGS) of cpDNA, and on the internal transcribed spacer (ITS) of nrDNA were studied. Phylogenetic trees based on the three data sets (matK, PY-IGS and ITS) were generated usingHamamelis japonicaandMytilaria laosensis(Hamamelidaceae),Cercidiphyllum japonicum(Cercidiphyllaceae), andDaphniphyllum calycinum(Daphniphyllaceae) as outgroups. The partition-homogeneity tests indicated that the three data sets and the combined data are homogeneous. A combined analysis also generated a strongly supported phylogeny. The phylogenetic trees show that the North American and western Asian species,L. styracifluaandL. orientalis, respectively, form a monophyletic group which is sister to the clade including all Asian species in the family. The genusLiquidambaris paraphyletic withAltingiaandSemiliquidambarnested within. Phylogenetic analyses of the molecular data indicate that taxonomic reexamination of the generic delimitation in the Altingiaceae is needed.
