Commelina caroliniana Walter is the correct name for a species that has often been confused with C. diffusa N. L. Burm. in the southeastern United States. It is lectotypified by a specimen in the Walter Herbarium. The North American plants of C. caroliniana are conspecific with plants of C. hasskarlii C. B. Clarke from India. Because C. caroliniana was published almost 100 years before Clarke's binomial, it must be taken up as the correct name for the Indian species. Commelina caroliniana was probably introduced into the United States in South Carolina with rice seed from India.
