e growth of most of the genus, is
injurious and sometimes even fatal to this species.

As it rarely ripens its seeds with us, it is generally propagated by
parting its roots in autumn. These are also usually imported from
Holland, and may be had of the importers of bulbs at a reasonable rate.

Being liable to be destroyed by seasons unusually severe, it will be
prudent to place a few roots of it in pots, either in the greenhouse or
in a hot-bed frame during the winter.

It bears forcing well.

This species of Saxifrage differing so widely from the others, both in
its habit and fructification, as to create a doubt in the minds of some,
whether it ought not to be considered as a distinct genus, is a native
of China, and one of the many plants which have been introduced into our
gardens since the time of MILLER.

Its round variegated leaves, and strawberry-like runners, the uncommon
magnitude of the two lowermost pendant petals, joined to the very
conspicuous glandular nectary in the centre of the flower, half
surrounding the germen, render this species strikingly distinct.

It is properly a greenhouse plant; in mild winters indeed it will bear
the open air, especially if placed at the foot of a wall, or among
rock-work; but, in such situations, it is frequently killed in severe
seasons.

It flowers in May and June, but does not produce its blossoms so freely
as some others.

No difficulty attends the propagation of it, for it increases so fast by
its runners, as to be even troublesome.
