A comprehensively sampled reassessment of the molecular phylogeny of the genistoid legumes questions the traditional placement of Haplormosia, an African monotypic genus traditionally classified within tribe Sophoreae close to the Asian-American geographically disjunct genus Ormosia. Plastid matK sequences placed Haplormosia as sister to the American-Australian tribe Brongniartieae. Despite a superficial resemblance between Haplormosia and Ormosia, a re-examination of the morphology of Haplormosia corroborates the new phylogenetic result. The reciprocally monophyletic deep divergence of the Haplormosia stem lineage from the remaining Brongniartieae is dated to ca. 52Mya, thus supporting a signature of an old single long-distance dispersal during the early Eocene. Conversely, we estimated a relatively recent long-distance dispersal rooted in the Early Miocene for the Australian Brongniartieae clade emerging from within a grade of American Brongniartieae. The Bayesian ancestral area reconstruction revealed the coming and going of neotropical ancestors during the diversification history of the Brongniartieae legumes in Africa and all over the Americas and Australia.
对染料木类豆科植物分子系统发育进行全面采样重新评估后，对单型属哈普洛莫西亚（Haplormosia）的传统分类位置提出了质疑。哈普洛莫西亚是一个非洲单型属，传统上被归类于槐族（Sophoreae），与亚美地理间断分布的红豆属（Ormosia）相近。质体matK序列显示，哈普洛莫西亚是美洲 - 澳大利亚布朗尼亚尔蒂族（Brongniartieae）的姐妹属。尽管哈普洛莫西亚和红豆属表面上有相似之处，但对哈普洛莫西亚形态的重新审视证实了新的系统发育结果。哈普洛莫西亚主干谱系与其余布朗尼亚尔蒂族的相互单系深分支可追溯到约5200万年前，因此支持了始新世早期一次古老的单次长距离扩散的特征。相反，我们估计澳大利亚布朗尼亚尔蒂族分支从美洲布朗尼亚尔蒂族的一个类群中分化出来，其根源是中新世早期相对较新的长距离扩散。贝叶斯祖先区域重建揭示了在非洲以及美洲和澳大利亚各地的布朗尼亚尔蒂族豆科植物多样化历史中，新热带祖先的来来去去。
