sides to a length of more than two feet, and covered with such an extraordinary profusion of beautiful white 
flowers, that the whole plant looks, at a little distance, perfectly white. The species was introduced in 1779. 

OTHER SPECIES OF CYTISUS. 
C. WELDENII Host. 
This species, which has been called the Dalmatian Laburnum, grows eight or ten feet high, and forms a very 
handsome bush, with abundance of yellow flowers. It has been said to differ from the Laburnum chiefly in its 
flowers being produced, in this country, in short thick racemes; though in its native country the racemes appear 
to be as long and drooping as the common Laburnum, according to the drawing sent by Baron Welden to 
Mr. Loudon for the “Arboretum Britannicum.” It is well-known that the seeds of several species of Cytisus are 
injurious, but in Cytisus Weldenti the whole plant is poisonous. The plant was introduced in 1840. 
C. RACEMOSUS Wedd. 
This species is now discovered to be the same as Genista bracteolata, and it is described under that name below. 

GENUS XXX. 
GENISTA Lam. THE GENISTA. 
Lin. Syst. MONADELPHIA DECANDRIA. 
Generic Caaracter.—Calyx bilabiate, upper lip bi-partite, lower | containing the pistil and stamens. Stamens monadelphous. Legume 
one tridentate, or five-lobed, the three lower lobes nearly joined to | compressed, rarely rather turgid, many-seeded, rarely few-seeded, 
the apex. Vexillum oblong-oval. Carina oblong, straight, not always | glandless. (G. Don.) 
Description, &c.—The word Genista is said to be derived from the Celtic word gen, signifying a small bush. 
Most of the species are hardy plants, but some few are sufficiently tender to require a greenhouse in Great 
Britain. Many of the species are included by some botanists in the genus Cytisus, and others in Spartiwm. 
1—GENISTA CANARIENSIS Lin. THE CANARY GENISTA. 
Synonymes.— G. rhodopnea Hort.; Spartium albicans Caw. ; Spreciric Cuaracter.— Leayes ternate, oblong, pubescent beneath, 
Cytisus paniculatus Zozs.; C. ramosissimus Poi, and covered with spreading hairs. Peduncles many-flowered, terminal. 
Enerayine.— Bot. Reg., t. 217. Branches angular. 
Description, &c.—This is one of the oldest inhabitants of our greenhouses, having been in cultivation ever 
since 1656. It is a very pretty plant, with glaucous leaves, and a great abundance of yellow flowers. It bears 
considerable resemblance to a hardy species generally called the Montpellier Cytisus (Genista candicans), but it 
differs in being less hardy. It is a very ornamental species, and when planted in the free ground of a conservatory, 
it forms a tall upright shrub. The flowers have a slight fragrance, faintly resembling that of the rose. 
2.—GENISTA BRACTEOLATA Link. THE RACEMOSE GENISTA. 
Synonymr.—Cytisus racemosus Webb. lets obovate, very obtuse, and narrower at the base. Racemes terminal, 
Encravinc.—Bot. Reg., for 1840, t. 23. elongated. 
Speciric Cuaracter.—Whitely pubescent. Leaves ternate; leaf- 
Description, &c.—A very handsome species, a native of Teneriffe, whence it was sent home by Philip Barker 
Webb, Hsq., in 1832, under the name of Cytisus racemosus, though it was afterwards discovered by him to be the
