Patterns of morphological variation were investigated in the genus Merciera A. DC. to re-assess the species boundaries. This study differs from previous studies in the genus because it employs multivariate statistical methods. Vegetative and floral characters obtained from herbarium specimens were analyzed. The results of cluster analysis and principal coordinates analysis support the recognition of six taxa.
