Lycopersicon was a genus in the flowering plant family Solanaceae (the nightshades and relative). It contains 13 confirmed species in the tomato group of nightshades; a few others might also belong here. First removed from the genus Solanum by Philip Miller in 1754, its removal leaves the latter genus paraphyletic, so modern botanists generally accept the names in Solanum. The name Lycopersicon (from Greek λύκοπερσικων meaning "wolf peach") is still used by gardeners, farmers, and seed companies. Collectively, the species in this group apart from the common cultivated plant are called wild tomatoes.
Cladistic analysis of DNA sequence data confirms Lycopersicon as a clade that is part of a lineage of nightshades also including the potato (S. tuberosum). If it is desired to continue use of Lycopersicon, it can be held as a section inside the potato-tomato subgenus whose name has to be determined in accordance with the ICBN.[1]

- Solanum pennellii Correll
Other "wild tomatoes"
Colloquially, wild tomato is used for several unrelated Solanum species with tomato-like fruit or leaves. The term is inaccurate and may be dangerous, as some of these species may be fatally poisonous:
- Physalis angulata (Cut-leaved Groundcherry)
- Solanum carolinense (Carolina Horsenettle)
- Solanum quadriloculatum (a "bush tomato" of Australia)
- Solanum wallacei (Wallace's Nightshade)
and others
