Among the very numerous Ep ge pat Patea in our gardens, and 
belonging to genera entirely,exotic, the most common are, amongst trees, 
—two species of Laburnum, the Robinias (commonly called Acacias, but 
not the Acacias of botanists); among shrubs,—the bladder Senna (Colutea 
arborescens), the Spanish Broom (Spartium junceum), several species of 
Caragana, Coronilla, &c.; in flower gardens,—several Lupines, the 
French Honeysuckle (Hedysarum coronarium), &c.; and in kitchen- 
gardens,—the French Bean (Phaseolus vulgaris), the Scarlet runner 
(Phaseolus cocevneus), &c. ; whilst the Australian Chorozemas, Kennedyas 
and others, the New Zealand Fdwardsias and Clianthus, the Kast Indian 
Piptanthus, Indigos, &c., the Chinese Millettia (Wistaria or Glycine of 
gardeners), and many others, from various parts of the world, are con- 
spicuous in our plant-houses or on garden-walls.
