About Synonyms

Very often one plant species can have several different scientific names. The previously accepted names are called “synonyms.” Scientific names are constantly changing thanks to our growing knowledge of plants. Some common reasons for name change are misidentification and reclassification. Although name changes can be frustrating, using the most up-to-date knowledge about which genus a plant belongs to allows for a more accurate placement in the ordering system of botanical classification.
