This was a study comparing several plants of the three different forms of Rosa roxburghii as well as R. sterilis, R. kweichonensis, R. laevigata, R. lucidissima, R. multiflora var. cathayensis, R. multiflora var. multiflora and R. omeiensis. Using morphological and genetic characteristics, which were then examined with statistical tools, the researchers tested the "genetic relatedness" of 13 different plants. In morphological traits, "Close relationships were found between...R. laevigata and R. lucidissima." Using RAPD analysis, R. laevigata and R. lucidissima formed a cluster. Using AFLP analysis and the statistical threshold determined by the researchers, R. laevigata and R. lucidissima are distinct species, although these two species were not the focus of the investigation.
