Among the very numerous Peafioiuers cultivated in our gardens, and 

 belonging to genera entirely exotic, the most common are, amongst trees, — 

 the Laburmim (Vythiis Laburnum), the Rohinias (commonly called Acacias, 

 but not tlie Acacias of botanists) ; among shrubs, — the bladder Senna {Co- 

 lutea arborescens), the Spanish Broom {Spartium junceum), several species 

 of Cytisus, Caragana, Coronilla, etc. ; in flower-gardens,— several Lupines, 

 the French HoneysucMe {Hedysarum coronarium), etc. ; and m kitclien- 

 gardens, — the French Bean {Phaseolus vulgaris), the Scarlet runner {Pha- 

 seolus coccineus), etc. ; whilst the Australian Chorozemas, Kennedi/as and 

 others, the New Zealand Edwardsias and Clianthiis, the East Indian Pip- 

 tanthus, Lidigos, etc., the Cliinese Millettia {Wistaria or Glycine of gar- 

 deners), and many others, from various parts of the world, are conspicuous 

 in our plant-houses or on garden- waUs.
