Discovered by Professor Gussone, on bills in the valley of
Amsanto, not far from Frigento, in the kingdom of Naples,
a spot famous for its mineral springs, and for the unhealthiness
of its air, arising from sulphureous exhalations.
The species is quite hardy, and from its trailing habit, and
copious clusters of golden flowers, is well suited to ornament
rock-work, where it will be found to thrive luxuriantly. It
may be increased, either by seeds or layers.
Our drawing was taken from a plant which flowered on
the rock-work in the Botanic Garden, Chelsea, in the begin-
ing of June last.
The generic name is derived, according to some, from
genu, the knee, from the flexibility of its branches; and by
others from gen, a celtic word, signifying a shrub. _D. Don.
