Mont. Voyage dans l'Amérique Méridionale Botanique 71 (1839). Radula subsimplex Steph. , Hedwigia 23: 130 (1884); Castle (1959: 21 , fig. 22); Yamada (1980: 254, fig. 9). — Type : Guadeloupe , without collector (holo-, G[G00043857]!, c. andr.). Further collection: Guadeloupe , “leg. Germain, misit Dr. l’Herminier” (G[G00112875!]), syn. nov . Remarks Radula pallens is a widespread neotropical species, that has been misunderstood in the past and was considered endemic to Jamaica (Gradstein in press). Radula subsimplex is a phenotype of R. pallens with lobule margins not sinuate. Several Caribbean species of Radula described by Castle (1959) in the section “ Dichotomae ”, such as R. obovata Castle and R. varilobula Castle , are probably further synonyms of R. pallens .
