The main range of this eastern species is to the north, but it is also widespread to the east and south of Ky. There is a coll. from ROWA (MDKY) labeled: K. Carr #570, 20 Aug 1936, sandy creek bank, Elliotsville. However, these data may be doubted (Campbell et al. 1992). Unlike other species of Utricularia reported from Ky., cornuta is generally attached to soil, with minute bladders on roots and minute linear leaves usually hidden below ground (versus dissected and conspicuous on floating stems); 2n = 18. A related species that may also be expected is U. subulata L., which is scattered widely over southeastern states and around southern Lake Michigan (K, W).
