Phylogenetic analyses recovered the two accessions of the new species to be sister to C. bracteata Roxb. ex DC. In turn, these two species formed the sister clade to the two accessions of C. incana L. The morphometric analyses revealed that all three species were distinct, while the analyses of distinctive characters enabled unambiguous distinction of the new species by its growth habit, leaflets, flower structure and pod morphology.
