68 Caryophylew—LDianthus. 
supposition sugeested by the long duration of the flowering 
season of the species in question. This is invariably sterile, and 
the new varieties obtained from it—one white and one striped 
—were simply accidental sports, which have been perpetuated 
by propagation from pipiues. Sterility, however, it should be 
observed, is not necessarily a proof of hybridity, because this is 
no infrequent consequence in double flowers. The Pink Flon 
is herbaceous and somewhat woody, forming thick spreading 
tufts, which throw up erect stems from a foot to a foot and a 
half high, terminated by large corymbs of double purple odori- 
ferous flowers of medium size. It is very hardy. 
An English gardener has described another hybrid, the issue 
of D. filgens impregnated by pollen from a double Carnation. 
This hybrid is remarkable for its immense corymbs of very 
double flowers of the most beautiful carmine. More recently, 
several French florists have offered a third hybrid for sale, the 
result, it seems, of a cross between D. supérbus, female, and a 
Japanese species, perhaps D. Chinéisis, male. 
2, TUNICA. 
Small slender rigid herbs resembling small Pinks. They 
differ from Diinthus in the few-nerved calyx. About ten 
species are known, all inhabiting the Mediterranean region; but 
only one species is at all generally cultivated. The name is 
from the Latin, signifying a jacket or covering. 
1. 2. Savifraga, syn. Gypséphila Sawxifraga.—A dwarf 
trailing plant with slender wiry stems and linear rigid leaves. 
The bright pink flowers are small, but being produced in 
copious panicles they are very effective. It is a native of the 
Pyrenees and Alps, and continues blooming all the Summer. 
3. GYPSOPHILA. 
Elegant perennial often glaucous herbs with small usually 
flat leaves and very small paniculate flowers. The species of 
this genus are remarkable for their graceful habit and nume- 
rous small flowers on slender pedicels. The reniform seeds 
and curved embryo, together with the different habit and small 
often minute flowers, distinguish this from the allied genera, 
There are nearly fifty species described, mostly from the South 
of Europe. From yiwos, lime or chalk, and giréw, to love, 
because many of them grow in this soil.
