Difference between Convolvulaceae and Solanaceae

Convolvulaceae and Solanaceae are two families of angiosperms belonging to the same order Solanales. The order Solanales belongs to the Asterid group of dicotyledons. Previously the order was named as Polemoniales. Let us find out the point of differences between these families.

Order: Solanales

Family: Solanaceae

The Solanaceae is the nightshade family of the Solanales order. They range from vines, lianas and epiphytes to shrubs and trees. About 98 genera and 2700 species of the family are known. Examples include potatoes, tomatoes, eggplants and tobacco.
