Differentiate between Fabaceae, Solanaceae and Liliaceae

Fabaceae, Solanaceae and Liliaceae are three families of the flowering plants. Let us know a little about these families before differentiating between them.

Family Fabaceae

Fabaceae, also known as the legume family, is the third-largest family in the Plant Kingdom after Orchidaceae and Asteraceae. 20,000 species are known in this family with about 765 genera. They are mostly found in the tropical regions, very few being found in temperate regions. It is one of the most economically important families as it includes daily use crops like peanuts, peas, moong and chickpea. Mulethi is used for medicinal purposes; soybean and groundnut are used to extract cooking oil.

Family Solanaceae

Solanaceae, also known as the nightshade or potato family, is the most utilised family by humans as it includes food like potato, tomato, eggplant, bell peppers, gooseberry, etc. It also has toxic plants like tobacco, belladonna, jimsonweed, mandrake, etc. On the other hand, some of the plants also exhibit medicinal properties. Around 3000 species of the family are known to humankind. They are well distributed throughout the Earth but are mainly found in tropical regions. Petunia is also a member of the solanaceae family which is an ornamental plant.

Family Liliaceae

Liliaceae, also known as the lily family, are known for their beautiful and decorative flowers such as lilies and tulips. About 600 species of the Liliaceae family are known. They are commonly found in temperate regions. Economical crops like onion, garlic and asparagus are members of the family.

Now that we know about the three families, let us look at the points where they differ.
