Three Taxa Constitute the Sexes of a Single Dioecious Species of Solanum

Summary Solanum appendiculatum H. et B. ex Dun., S. connatum Corr., and S. inscendens Rydb. constitute the single dioecious species, S. appendiculatum . These taxa are fully intercompatible and morphologically very similar. They were distinguished by differences in style length and in the degree of filament fusion; however, the first character is associated with the gender of the plants, and the latter shows variability and inheritance patterns not associated with species boundaries.
