636 ARBORETUM AND FRUTICETUM. PART IIT. 
A rapid-growing shrub, attaining the height of 
12 ft. or 14 ft. in 8 or 10 years; but, in British 
gardens, not of long duration. It is not un- 
common in Italy; and on Mount Vesuvius is 
found even on the ascent to the crater, where 
there are scarcely any other plants. It grows 
wild in the warmer parts of Switzerland, and 
in the south of Germany, and in France ; vary- 
ing in magnitude according to the soil and the 
situation. It was introduced in 1570, and pro- 
duces its yellow flowers from June to August ; 
the flowers are succeeded by large bladder-like 
legumes, which, as they ripen, become of a red- 
dish colour,and contain 15 or 20 seeds. These 
bladders, when pressed, explode with a crack- 
ling noise. On the Continent, the leaves have 
been recommended as a substitute for senna, and they are also said to 
afford a grateful food for cattle. The seeds, in doses of a drachm or two 
are said to excite vomiting. In British gardens, the plant is chiefly valuable 
as a bulky fast-growing shrub, of the easiest culture, and fit for almost 
any situation. Price, in the London nurseries, 9d. each; at Bollwyller 
50 cents; and in New Yerk, 373 cents. ;

Spec. Char., §c. Leaflets obovate, emar- 
ginate, glaucous. Peduncles bearing 
4—5 flowers.  Callosities of the 
standard obtuse, very small. Legumes 
opening at the tip. Corolla, in 
colour, between red and saffron-co- 
loured, with a yellow spot at the base 
of the standard. (Dec. Prod., ii. 
p. 270.) A shrub, like the former, 
but of smaller dimensions, and with 
leaflets more glaucous, and more re- 
tuse. A native of the Archipelago, 
Georgia, and the Levant. It was in- 
troduced into England in 1731, and 
produces its reddish copper-coloured 
flowers in June and July. Plants are 
common in the nurseries, and they 
are sold at the same prices as plants of 
the preceding species.

Spec. Char., §c. Leaflets obcordate, glaucescent. Peduncles usually 6-flowered 
Legumes closed at the apex. Flowers orange-coloured. (Don’s Miil., ii. 
p. 245.) A shrub, rather larger than the preceding sort, and differing from 
it chiefly in having orange-coloured flowers. It is, perhaps, a hybrid be- 
tween the two preceding sorts.
