DNA analysis identifies 'Solanum' from Litchfield National Park as a lineage of 'S. dioicum'

The uncommon reproductive system of dioecy is somewhat widespread in Solanaceae, being exhibited by members of five genera within this family. These members represent, however, only around 1% of species within the Solanaceae. The highest incidence of dioecy is found in the genus Solanum, where around 15 species have been described as consisting of populations in which individual plants are either "male" (staminate) or "female" (pistillate). Ten of these Solanum species, commonly known as
