Based on sequence data of nuclear ITS and plastid matK, trnL-F and psbA-trnH markers, the phylogeny of the subtribes Caraganinae and Chesneyinae in tribe Caraganeae was inferred. The results support the monophyly of each of the subtribes. Within subtribes Caraganinae, Calophaca and Halimodendron are herein transferred into Caragana to ensure its generic monophyly. The subtribe Chesneyinae is co...
