利用核ITS rDNA、叶绿体rbcL和matK外显子、rps16内含子以及trnL-F内含子和基因间隔区的序列数据进行了全面的分子研究，以评估厚朴的分类地位，并评价了Pimelea Banks&Sol内的亲缘关系。前加尔特恩。和百里香属(Thymelaeaceae)。这两个属都是澳大拉西亚人，他们组成了Pimeleinae亚族，其特点是雄蕊减少到两个。以往的研究表明，热带非洲的Pimelea、Thecanths和Gndia L.种之间关系密切。我们的结论是，Pimelea和Thecanths形成了一个强有力的支系，Thecanths可能包括在Pimelea中，尽管我们在正式提出一系列新的分类组合之前等待进一步的数据。
A comprehensive molecular study, using sequence data from nuclear ITS rDNA and plastid rbcL and matK exons, rps16 intron, and the trnL-F intronic and intergenic spacer, was used to assess the taxonomic status of Thecanthes Wikstr., and to evaluate the relationships within Pimelea Banks & Sol. ex Gaertn. and Thecanthes (Thymelaeaceae). Both genera are Australasian and they constitute the subtribe Pimeleinae, which is characterised by a reduction to two stamens. Previous studies indicated a close relationship among Pimelea, Thecanthes and Gnidia L. species from tropical Africa. We conclude that Pimelea and Thecanthes form a strongly supported clade, with Thecanthes possibly included within Pimelea, although we await further data before formally proposing a series of new taxonomic combinations.
