232 FAMILIES OF FLOWERING PLANTS 
Fic. 201. The Wild Bergamot (Monarda fistulosa). After Britton and 
Brown, Ill. Fl. Northeast U. S. 
plant, belongs with the mints, as does also the little ground ivy (Gle- 
coma). The Pacific Coast has a number of ornamental species in 
Ramona, Stachys and Monardella. The largest flowered of our eastern 
mints are found in Physostegia, the false dragon-head. The general 
type of labiate flower is shown in Fig. 202. 
Family Nolanaceae. Nolana Family. Consists of about 40 species, 
comprised in the single genus Nolana, which was formerly included in 
the Solanaceae. They are South American herbs or undershrubs, with 
rather pretty flowers, very similar in structure to the nightshades. 
Family Solanaceae. Nightshade Family. Includes about 70 genera 
and 1600 species, most abundant in the tropics. They are herbs, shrubs 
or vines, or rarely trees, with usually alternate leaves and cymose 
flowers. The calyx and corolla are 5-lobed, the latter with the lobes 
plicate (folded) in the bud. Stamens as many as the lobes of the corolla 
and alternate with them, all equal exceptin one genus. Ovary superior, 
2-celled, becoming in fruit a berry or a capsule with numerous seeds. 
The family, as a whole, possesses strongly narcotic and poisonous 
properties. These are particularly prominent in Atropa, which yields 
the drug belladonna; in Hyoscyamus, the henbane ; and in many species 
of Solanum or nightshade. The latter is the largest genus of the family, 
containing fully 900 species, exhibiting a wide variety of form and uses. 
The most important from the economic standpoint is the potato (Sola- 
num tuberosum), the tubers of which lose their poisonous principle by
