- 3. Solanaceae • Solanaceae familyis also known as the potato family. • Around 2000 species of dicotyledonous plants belong to this family. • Solanaceae is a family of angiosperms. • It is widely distributed all over the world in tropical, subtropical and temperate zones. • It includes a number of spices, medicinal plants, agricultural crops, etc. Vegetables like potatoes, tomatoes, bell peppers, eggplant are included in the Solanaceae family.
- 4. Systematic Position OfSolanaceae • Kingdom: Plantae • Subkingdom: Tracheobionta • Super Division: Spermatophyta • Division: Magnoliophyta • Class: Magnoliopsida • Subclass: Asteridae • Order: Solanales • Family: Solanaceae

Some common examples are:

- 9. Description Of TheFamily (1) • Habit: Solanaceae family contains herbs, shrubs and also some small trees. • Root: Typically they possess a tap root system with branching.
- 10. Description Of TheFamily(2) • Stem: Aerial, branched, erect, mostly herbaceous, cylindrical, hairy or glabrous. Potato is an example of an underground stem. • Leaf: Leaves are simple, alternate and sometimes pinnately compound. Venation is reticulate. Leaves are exstipulate or sessile. Sometimes transformed into spines. • Stem of Solanaceae plant Leaves of S. tuberosum
- 11. Description Of TheFamily(3) • Inflorescence: Flowers are solitary or grouped having axillary or cymose inflorescence. • Flower: Bracteate or ebracteolate, actinomorphic and generally hermaphrodite. The flower is pentamerous and hypogynous.
- 12. Description Of TheFamily(4) • Calyx: Sepals green or colored, typically 5 sepals, gamosepalous, persistent and show valvate aestivation. • Corolla: Petals 5, gamopetalous and valvate or imbricate aestivation. Flowers of potato Flowers of Datura sps. Flowers of Datura sps.
- 13. Description Of TheFamily(5) • Androecium: Stamens 5, polyandrous and epipetalous. • Gynoecium: Bicarpellary, syncarpous with the superior and bilocular ovary. Each locule contains many ovules (1-50). The placenta is swollen and axile placentation. The ovary is placed obliquely. It contains one style and one simple or bilobate stigma. • Fruit: It can be berry, e.g. tomatoes or capsule as in datura. • Seeds: Contains many seeds that are endospermic. Seeds are mostly round and flat. The embryo is curved or straight with two cotyledons. Mostly plants contain 2n = 24 (2 x 12) chromosomes but polyploidy is also seen with chromosomes in multiples of 12. • Pollination: Members of this family mainly exhibit entomophilous pollination, i.e. pollinated by insects.

- 16. Vegetative Characters •Root System:Taproot system. •Stem: Erect or climber; Solanaceae includes herbs, shrubs, small trees, and climbers. •Leaves: Alternate, simple or pinnately compound (rarely); exstipulate; reticulate venation.
- 17. Floral characters • Inflorescence:Racemose- terminal or axillary raceme; Cymose- solitary in Solanum. • Flower: Complete, bisexual, actinomorphic, hypogynous. • Calyx: Five sepals, gamosepalous; valvate aestivation. • Corolla: Five petals, gamopetalous, valvate aestivation. • Androecium: Five stamens, epipetalous; anthers basifixed. • Gynoecium: Syncarpous, bicarpellary, bilocular, superior ovary, axile placentation. • Fruit: Berry/ capsule. • Seed: Numerous, endospermous

- 20. Economic Importance • Theseare an important source of vegetables. E.g. tomato, brinjal and potato, bell peppers, capsicum etc. • Many plants are of medicinal importance. The main medicinal plants are Atropa belladonna, Withania somnifera (Ashwagandha), Datura, etc. • Some alkaloids are toxic too. Some of the important alkaloids are tropanes, nicotine, capsaicin, solanine, hyoscyamine, etc. • Many ornamental plants also belong to this family. E.g. Petunia, Lycianthes, Cestrum, etc. • These are important sources of spices. E.g. chilly • The leaves of Nicotiana tabacum are a major source of tobacco. Tobacco is a commercially very important plant.
