THE LADIES’ FLOWER-GARDEN 
5.—BROWALLIA CORDATA, G. Don. THE CORDATE-LEAVED BROWALLIA. 
Synonyme. — B. grandiflora, Lindl. cles 1-fiowered, racemose at the tops of the branches. Branches and 
Engraving. —Bot. Reg. t. 1384. adult calyxes glabrous.—(G. Don.) 
Specific Character. —Leaves cordate-ovate, acuminated. Pedun- 
Description, &c. —This is the plant figured under the name of B. grandiflora in the Botanical Register, but it 
differs considerably from the plant to which the same name is given in the Botanical Magazine. The flowers are 
much smaller, they are of a deeper blue, or of pure white, with a dark yellow eye, and the under side of the petals 
is yellow; the leaves are cordate, and of a dull green; and the wdiole plant is smaller. It is a native of Peru, 
and was introduced in 1829. The culture is the same as that of the other species. 
CHAPTER XLI. 
SOLANACE/E. 
Essential Character. —Calyx usually 5-cleft, persistent. Corolla 
usually 5-cleft, monopetalous, usually regular. Stamens usually 5, 
epipetalous. Style one. Fruit capsular or baccate, 2 to 4-celled. 
Albumen fleshy. Herbs or shrubs with a peculiarly nauseous smell. 
Leaves alternate. Inflorescence variable, but generally extra-axillary. 
—(G. Don.) 
Description, &c. —The order Solanaceie is a very interesting one, as it contains not only many useful plants, 
such as the common potato, the capsicum, and the tomato, but some of our most splendid flowers, such as the 
Daturas and Brugmansias, the Petunias, and the different kinds of Tobacco. Many botanists include the genera 
Salpiglossis, Scliizanthus, and Browallia, in the Solanaceee; but others place them, as we have done, in the 
Scrophularime. Several of the plants belonging to Solanaceas are narcotic poisons; as, for example, the deadly- 
nightshade, the henbane, and the thorn-apple. All the species require a rich free soil, and they are all robust 
and vigorous-growing, taking up a great deal of room, and being therefore quite unfit for small gardens. 
GENUS I. 
NICOTIANA, Toum. THE TOBACCO. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Generic Character. —Calyx tubular. Corolla funnel-shaped, or salver-shaped; limb equal. Stamens rather unequal, inclosed or exserted. 
Capsule dehiscing by 4 parts at the apex ; placentas free.—(G. Don.) 
Description, &c._ The different kinds of Tobacco have all ornamental tube-shaped flowers, and very large 
thick leaves, which are used for making tobacco and snuff. They are cultivated for these purposes abroad, and 
sometimes even in England ; though in this country they are generally grown for their flowers, and, in fact, no 
person is here permitted to grow more than half an acre of tobacco without purchasing a licence from the Excise. 
The different kinds of Tobacco are by no means common in gardens, partly on account of the room they take up 
from their thick and branching stems and tne large size of their leaves, and partly on account of their rapidly 
exhausting the soil. The name of Nicotiana was given to the genus by Tournefort, in honour of M. Nicot, the 
French ambassador to Portugal, who introduced the first species of it into France ; and that of Tobacco, from the 
name given by the native Indians to the pipe they used in smoking. The principal species grown for their leaves 
are, N. tabacum , the Virginian tobacco; N. macrophglla , the Oroonoko tobacco; and N. rustica, the common tobacco.
