Dicotyledons with Gamopetnlous Flowers — Polemoniacece. 
Distribution. —A small Natural Order, chiefly confined to North America, with a few species in 
the cooler parts of Western South America, as well as in Europe and North Asia. The only British 
representative, Jacob’s Ladder (Polemonium cceruleum), is common to the Northern continents. 
One British Genus; Species, i. 
Stem erect; in Cobcea twining. 
Leaves undivided ; or, in Jacob’s Ladder or Greek Valerian, pinnately divided. 
USES, &c.—The Order does not afford any important economic product. Many species are favourite garden 
flowers, as Jacob’s Ladder, the numerous varieties of Phlox, and the pretty annuals Gilia, Leptosiphon, and Collomia. 
Cantuas and the twining Cobsea are grown in plant-houses. All of these are well marked by the association of a 
trimerous symmetry in the pistil with a regular gamopetalous corolla. 
Natural Order 
SOLANACE^E. Tab 61. 
Diagnosis.— Herbs shrubs or small trees, usually with alternate leaves. 
Corolla hypogynous, regular or nearly so. Stamens epipetalous, as many 
as lobes of corolla and alternate with them. Ovary 2-celled, with numerous 
ovules. Seeds albuminous, usually with a curved embryo. 
Distribution. —A large Natural Order, by far most numerous in Equatorial regions of the Old 
and New World. Several genera, however, are represented both in the North and South Temperate 
zone, although no species attain high elevations or an Arctic latitude. The principal genus, Solamcm, 
represented by 2 species in Britain, includes about 900 species, chiefly Tropical.
