2 Flower and pollen morphology of Solanum ossicruentum, a functionally dioecious bush tomato from Australia. Every Australian bush tomato species previously identified as androdioecious has now been confirmed as functionally dioecious, plus a number of species described since Symon's monograph that share the same morphology (e.g. [7]; [11]; [18]). The ecology, evolution, and biogeography of dioecy in the genus Solanum: with paradigms from the strong dioecy in Solanum polygamum, to the unsuspected and cryptic dioecy in Solanum conocarpum. Andromonoecy, in which every individual plant bears flower clusters consisting of a (typically) single cosexual flower plus numerous unisexually "male" flowers; where every flower produces functional pollen but only the cosexual flowers can set fruit/seeds.
