Solanum perlongistylum is an evergreen vine in the family Solanaceae. It is endemic to Peru, and is a close relative of S. muricatum, the domesticated pepino. Its style is the longest in the group, and its flowers have a higher pollen:ovule ratio. It is self-incompatible. It is diploid at n  =  12. Together with Solanum catilliflorum, it might be an allopatric variant of S. caripense.

Solanum catilliflorum is an evergreen vine in the family Solanaceae. It is endemic to Peru, and is a close relative of Solanum muricatum, the domesticated pepino. It bears small, dish-shaped flowers (thus named catilli-florum: Latin for "dish" and "flower") and is self-compatible and autogamous, with short styles like those that characterize all self-compatible species in this group. It also has a low pollen:ovule ratio, which is characteristic of self-compatible species in the group. It is diploid at n  =  12. Together with Solanum perlongistylum, it might be an allopatric variant of S.

Solanum cowiei is a small fruiting subshrub in the family Solanaceae. It is endemic to the Northern Territory in Australia. The fruit is a green berry, up to 15 mm in diameter, that later becomes black-green and detaches from the calyx. The species was formally described in 2013 by Christopher T. Martine. The specific epithet honours Dr. Ian Cowie, the Chief Botanist at the Northern Territory Herbarium. It is placed within the "Dioicum Complex" of Solanum subgenus Leptostemonum.

Solanum plastisexum is a species of bush tomato from the Australian monsoon tropics that exhibits "breeding system fluidity" – that is, it has no stable sexual expression. After its first description in 2019, the describers suggested the common name of Dungowan bush tomato, in reference to Dungowan Station where it was collected. The species is restricted to a small area in the central region of the Northern Territory of Australia on and around the Buchanan Highway. It confounded field botanists since at least the early 1970s because it does not conform to any one floral form and/or
