 green frame shrub, introduced from the south of Europe 

 in 1683, and producing showy yellow flowers in July and

 troduced from the Cape of Good Hope in 1774, and flower-

 house biennial, introduced from the Cape of Good Hope in

 pretensions to beauty : they are easily preserved in light 

 soil, and increased by seeds or cuttings.

 nial, introduced from the Cape of Good Hope in 1691, and 

 flowering in May and June. It grows in light soil, as loam

 a low spongy-wooded green -house shrub, of no beauty, 

 introduced from the Canaries in 1779, and flowering from 

 May to September. It grows in sandy loam, and is easily 

 increased by seeds or cuttings.
