Subfamily Cercidoideae is an early‐diverging lineage of Leguminosae, within which the number and classification of genera have been controversial. Cheniellais a recently described genus in the Cercidoideae which requires revision and testing of its monophyly and circumscription. Here we infer the phylogenetic position and infrageneric relationships of Cheniellaas well as the intergeneric relationships of Cercidoideae using 48 newly sequenced plastid genomes, including 34 individuals representing all species of Cheniella. Our phylogenetic analyses yield a well‐resolved tree of Cercidoideae with robust support at most nodes. We also present morphological studies through field work and herbarium studies to re‐assess the classification and circumscription of the genus. Based on the results of molecular analyses and morphological studies combined with distribution data, we broaden the circumscription of Cheniellato comprise a total of 15 species and 3 subspecies, including three new species (C. hechiensis, C. longistaminea, C. pubicarpa), one new combination (C. tianlinensis) and one new status and combination (C. longipes). |
