| Summary: | Dactylicapnos torulosa (Hook. & Thoms.) Hutch. is a commonly used medicinal plant in southwest China. In this study, we sequenced the complete chloroplast genome of D. torulosa and explored phylogenetic relationship of the species and its related species. The genome size is 166,238 bp with typical quadripartite structure. A pair of inverted repeats (IRs) of 37,115 bp are separated by a small single copy (SSC) region of 18,627 bp and a large single copy (LSC) region of 73,381 bp. In total, 107 genes are annotated, including 76 protein coding genes, 27 transport RNA, four ribosomal RNA. Moreover, 13 genes are found to contain introns. Phylogenetic analysis showed that Dactylicapnos torulosa formed a basal branch instead of gathering together with Corydalis, which was inconsistent with the traditional treatment on Fumarioideae. This study provides useful information for phylogeny and conservation of the species and its relatives.
