The Genus Astrantia, commonly known as "Masterwort," belongs to the family Apiaceae. This genus includes almost 20 different species of flowering plants that are native to Europe and Asia. The plants are characterized by their unique star-shaped flowers that grow in clusters and have an umbel-like appearance. They also have basal leaves that form a rosette and stem leaves that alternate. Some synonyms for the Genus Astrantia include Melanelia and Corymbium. These names have been used in the past but are now considered obsolete. Despite this, they showcase the complex history of botanical nomenclature and the ongoing work of taxonomists to understand and categorize the natural world.
