Fam. 118. Solanaceae Juss. Potato or Nightshade Family 



Herbs, shrubs or trees; leaves alternate or fascicled, sometimes with some 

 opposite, entire to odd-pinnate; flowers in umbels, cymes or panicles, or solitary 

 and lateral, perfect, regular or nearly so, 4- to 6-merous; calyx usually 5-toothed 

 or 5-cleft (rarely 4-toothed), rotate, campanulate or tubular, usually persistent; 

 corolla tubular, campanulate, infundibuliform or rotate, usually more or less 

 5-lobed, with the lobes valvate or imbricate and usually plicate in bud; stamens 

 usually 5, distinct or slightly united by the anthers; filaments distinct, inserted 

 on the corolla tube alternate with the lobes; anthers opening by slits or pores; 

 styles 1 ; stigma entire or 2-lobed; ovary superior, usually 2-celled; fruit a berry 

 or capsule. 



A family of about 2,100 species in about 90 genera, widely distributed but 

 mostly in the Western Hemisphere. 



This family contains a number of important economic species, among which 

 are the potato {Solanum tuberosum), egg-plant (5. Melongena), tomato (Lyco- 

 persicon esculentum), red-pepper {Capsicum spp.) and tobacco (Nicotiana 

 Tabacum). As its somber vernacular name, "Nightshade," implies it also contains 

 a number of very poisonous species, among which are henbane (Hyoscyamus 

 niger) and belladonna (Atropa Belladonna), which are sources of the powerful 

 drugs hyoscymine and atropine, respectively. A number of genera have ornamental 

 species that are widely grown horticulturally, among which are Petunia, Solanum 

 and Nicotiana.
