G. canariénsis L., the Spartium 4lbicans of Cavanilles, the Cytisus paniculatus of Lois., and 
the C. ramosissimus of Poir., (Bot. Reg., t. 217.) is a native of the Canary Islands and of Spain, 
which has been an inhabitant of British green-houses since 1656. It is a showy shrub, growing 
to the height of 8 ft. or 10ft.; very leafy, with terminal heads of 
flowers, the petals of which are of a cream colour. In dry warm 
situations, it will grow in the open air with very little protection. 
A plant has stood out against a wall in the Horticultural Society’s 
garden since 1832. 
G. linifolia L., Spartium Jinifdlium Desf., Cytisus dinifdlius Lam., 
Genistiides Jinifdlia Maench, (Bot. Mag., t.442.; and our fig. 280.) 
is a native of the south of France,and of Spain, and also of Barbary. 
It grows to the height of 6 ft., and flowers in our green-houses from 
January to June. It has been in cultivation since 1739; but, from 
its flowering in the winter season, it is not so well adapted for the open 
air as most of the half-hardy species. It is, however, an admirable 
plant for a conservative wall, where the protection is a glass case. 
G. bifldra Dec., Spartium biflbrum Desf. Fl. Aél., 2. p. 133. t.179., is 
a shrub from 1ft. to 3ft. high, a native of the north of Africa, not 
: , _ yet introduced. 
G. microphglla Dec., Spartium microphyllum Cav. Ann., 1801, p. 63., is a shrub from 1 ft. to 
ft. high, a native of the Grand Canary Island on mountains, not yet introduced; unless this, 
and other species from the Canary Islands, should have been sent... 
home, by Philip Barker Webb, Esq., to the Milford Nursery. 
G. tridens Cav. (Don’s Mili., 2. p.151.) grows 2ft. high in the north 
of Africa, about Tangier, but has not yet been introduced. 
G. egyptiaca Spreng. grows to the height of 2ft. in Egypt, and ap- 
proaches very near to G. hispanica, of which it is probably only a variety. 
G. virgata Dec., Spartium virgatum Ait., G. gracilis Poz., Cytisus tener 
Jac. Icon. Rar., t.147., and our fig. 281., is a handsome shrub, a native of 
Madeira, growing to the height of 3 ft. or 4 ft., and flowering from March 
to July. it has been an inhabitant of our green-houses since 1777, but 
will grow against a wall with very little protection. 
G. cuspidisa Dec,, Spartium cuspidatum Burch., is a native of the Cape 
of Good Hope, and grows to 2 ft. or 3 ft. high. It is a much-branched stiff 
shrub, and, probably, rather more tender than the preceding species given 
as half-hardy. 
G. congésta Dec., Spartium ‘congéstum JVilld., is a native of Teneriffe, 
nearly allied to G. virgata, and, doubtless, only a variety of it. 
G. desiderdta Dec., a native of Port Desideratum, and G. scandens Lois. - 
a native of Cochin-China, are very doubtful plant d y
