Advances in both laboratory methods (e.g. capillary DNA sequencing technology) that allowed easier sequencing DNA and computational methods that make better use of the data (e.g. employing coalescent theory) have helped improve phylogeographic inference.
In a large-scale phylogeographical study of this species conducted using Chloroplast genome sequences, a group of researchers from Central University of Punjab, Bathinda have found that this plant had been originated in North-Central India.
