Numerical technique has been used to construct the cladogram to depict
the natural relationships among the species of the genus Sibbaldia. T
he cladistic analysis of the genus is presented with a discussion of c
haracters used and the result suggest the exclusion of S. micropetala
from the genus Sibbaldia. The transfer of S. adpressa by Juzepczuk (19
41) to the monotypic genus Sibbaldianthae is rejected.
