Phylogenetic analyses of early-diverging Faboideae have indicated that genera previously positioned in distinct tribes are instead closely related, e.g. in the Amburaneae clade, and the relatively recent rearrangements of many genera into clades has hampered the identification of morphological synapomorphies for previously unrecognized clades. Our aims are to evaluate anatomical vegetative characters of leaflets attached to reproductive features in the Amburaneae clade, to identify new synapomorphies for the clade and subclades, to identify characters supporting intergeneric relationships and diagnostic characters for the genus and species and to provide information about the morphology and histochemistry of secretory structures. The study was based on the anatomy of the leaflet of 19 species of the Amburaneae clade. Papillae cells, the presence of vascular system units and hypodermis are shared features of Amburaneae. Anatomical characters of the leaflet can be diagnostic at the generic and specific levels in Amburaneae. Secretory structures found in the clade are secretory cavities, secretory channels, idioblasts, mucilaginous epidermal cells and glandular trichomes. The broader concept of Amburaneae is reinforced here by morphological and molecular data, with the identification of new synapomorphies. Our dataset supports the intergeneric relationships resolved by molecular data.

伞形科进化枝的解剖学研究（Fabaceae：Faboideae）

对早散的美洲豹科的系统发育分析表明，先前位于不同部落的属却是紧密相关的，例如在安布兰属进化枝中，许多属相对较近的重排成进化枝阻碍了对先前未被认识的进化枝的形态同形亚型的鉴定。我们的目的是评估附着于Amburaneae进化枝的生殖特征的小叶的解剖营养特征，确定该进化枝和亚进化枝的新突触，鉴定支持属和种间属关系的特征和诊断特征，并提供有关形态的信息和分泌结构的组织化学。该研究基于19种Amburaneae进化枝的小叶的解剖结构。乳头细胞 血管系统单位和皮下组织的存在是伞形科的共同特征。小叶的解剖特征可以在伞形科的一般和特定水平上进行诊断。在进化枝中发现的分泌结构是分泌腔，分泌通道，成纤维细胞，粘液表皮细胞和腺毛。形态学和分子数据，并鉴定了新的突触型，从而增强了菊科的广泛概念。我们的数据集支持通过分子数据解析的属间关系。粘液表皮细胞和腺毛。形态学和分子数据，并鉴定了新的突触型，从而增强了菊科的广泛概念。我们的数据集支持通过分子数据解析的属间关系。粘液表皮细胞和腺毛。形态学和分子数据，并鉴定了新的突触型，从而增强了菊科的广泛概念。我们的数据集支持通过分子数据解析的属间关系。
