    Species typica, Aranella fimbriata (H. B. K.) Barnh. (Utricularia fimbriata H. B. K.).

    This genus is monotypic, the single described species widely distributed in tropical and subtropical America. In size, number of flowers, and number and cutting of the scales, it is variable, and it may be possible to recognize eventually several species. By the blunder of a careless worker nearly 80 years ago, this plant was erroneously referred to the very different genus here called Cosmiza; the error has been perpetuated in German botanical literature, and even in Engler & Prantl's Natiirlichen Pflanzenfamilien, in 1893, the calyx and bracts of this species (as Polypompholyx laciniata) are figured to illustrate the 4-parted calyx of the Australian genus.
