Species 3 (3 in the flora).
Wislizenia has been the object of diverse taxonomic opinions; as many as eight or as few as one species have been recognized. S. Keller (1979) documented three geographically and morphologically distinct groups within the genus. Although she treated those as subspecies, recognition as species seems more appropriate (H. H. Iltis, pers. comm.). The differentiation among the taxa seems equal to or greater than that among species in other genera of the family.
