Genus Collinsia is the scientific name for a group of flowering plants native to North America. Although the name Collinsia is unique and refers specifically to this genus, there are several synonyms that have been used in the past depending on the classification system being used. Some of these include Nuttallanthus, Limnorchis, and Mentzelia. These synonyms may lead to confusion when trying to identify a specific species within the genus, but they can also provide helpful historical context for understanding the taxonomy of these plants. Regardless of the name used, Collinsia species are known for their distinctive blue to purple flowers with contrasting white or yellow markings.
