same as the Genista bracteolata of Link. The species is very ornamental, and it may be grown readily from 
cuttings. It does best planted out in the ground of a conservatory, where it forms a handsome bush, covered with 
fragrant flowers, which continue appearing from about Apyil till the end of the summer. 
OTHER SPECIES OF GENISTA. 
G. LINIFOLIA Zin. 
A pretty little plant with silky leaves, which are quite white on the underside, and a profusion of golden 
yellow flowers. The plant is a native of the South of Spain, and it was introduced in 1786. It is sometimes 
called Cytisus argenteus. 
G. VIRGATA Dee. 
This is a very handsome plant, a native of the Canary Islands, whence it was introduced in 1825. It is very 
nearly hardy, and will live in tolerably mild seasons in the open border, but it will not resist a severe frost.

Description, &c.—This genus derives its botanic name from a Greek word signifying scurfy, in allusion to the 
calyx and many other parts of the plant being covered with small tubercles. The flowers are generally blue and 
white, or purple and white, and they are produced in tufts at the extremity of the branches. The species are 
generally natives of the Cape of Good Hope, though others come from North America, Eastern Europe, and various 
other parts of the globe. The plants are generally ornamental, and the flowers are very large in proportion to the 
leaves. The species are very numerous.

Description, &c.—Most of the plants belonging to this genus produce indigo, from the pulp or cellular tissue 
of their leaves. They are generally ornamental, but not so much so as most of the other plants belonging to the 
order. Many of the kinds are stove plants, and those which will live in a greenhouse in this country are generally 
natives of the Cape of Good Hope. The species most commonly used for producing indigo (Indigofera tinctoria) is 
found wild both in the Hast and West Indies, and also in Central Africa, but it requires a stove in Great Britain 
The name of Indigofera signifies indigo-bearer, in allusion to the principal product of the plant.
