POPULAR GARDEN BOTANY. 



A CANTHA CEJE. 



Exogens, having flowers with bracts, sometimes large and 

 leafy. Calyx four or five-parted, or in many pieces. Corolla 

 monopetalous, below the ovary, bearing the stamens, mostly 

 irregular ; the limb gaping, or one or two-lipped. Stamens mostly 

 two, sometimes four. Leaves opposite, rarely in fours, sometimes 

 sinuated or lobed. — Herbaceous plants or shrubs ; natives chiefly 

 of the tropics. 



THUNBERGIA. 



Gen. Char. (Didynamia Angiospermia.) Calyx double, outer 

 two-leaved, inner about twelve-toothed ; corolla bell-shaped ; 

 capsule beaked, two-celled.

 One species, T. Capensis, with straw-coloured flowers, is 

 sufficiently hardy to flourish in the greenhouse, where it is 

 handsome as a climber. T. alata, though a native of the 

 East Indies, and generally treated as a stove-plant, will also 

 flourish in the greenhouse, at least in the summer, when it 

 will blossom freely ; it should be trained to a wire frame, 

 about six feet high, formed of four uprights fitted into the 

 pot, and wire spirally coiled round ; the plant is then well
