|Solanum melongena (Aubergine)|
Juss. ex Bercht. & J.Presl, 1820
Under the older Cronquist system, the latter three families were placed elsewhere, and a number of others were included:
- Family Duckeodendraceae (now treated as a synonym of Solanaceae)
- Family Nolanaceae (now treated as a synonym of Solanaceae)
- Family Cuscutaceae (now treated as a synonym of Convolvulaceae)
- Family Retziaceae (now treated as a synonym of Stilbaceae, order Lamiales)
- Family Menyanthaceae (now placed in order Asterales)
- Family Polemoniaceae (now placed in order Ericales)
- Family Hydrophyllaceae (now treated as a synonym of Boraginaceae)
The following families are included here in newer systems such as that of the Angiosperm Phylogeny Group (APG):
- Family Solanaceae (nightshade family; includes Nolanaceae as well as potatoes, eggplants, tomatoes, chilli peppers, tobacco, and petunias.)
- Family Convolvulaceae (morning glory and sweet potato)
- Family Montiniaceae
- Family Sphenocleaceae
- Family Hydroleaceae
The APG II classification treats the Solanales in the group Euasterids I.
