ecimens of this Saxifrage, though small, are exceedingly pretty.
Excepting when there is fog or rain, it is nearly white; and the
rosettes, of various sizes, from 1/4in. to 1in. across, are not only neat
in themselves, but are densely and pleasingly arranged in a hard flat
mass. It is never more beautiful, not even in May and June, when it
flowers, than in November, when the growth is both complete and ripened,
and the scaly substance which is spread over the leaves and the silvery
teeth combine to render it attractive.

The flowers are of the usual form, and are produced on stems 4in. to
6in. high; they are white. The leaves seldom exceed 1/2in. in length and
1/8in. in width; they are spathulate in form, stout, and rigid. The
rosettes are somewhat flattened and numerous, and give the idea of
greenish-white flowers.

_S. p. hybrida_ is a variety of the foregoing species, and without
pretending to say what the type has been crossed with to produce this
handsome form, I may, for the purpose of conveying an idea of what it is
like, say that it approaches _S. aizoon_, which also flowers in May and
June. In all its parts it is larger than the type; the leaves are
greener and more strap-shaped, and are more erect, but not so rigid; the
habit, too, differs--it forms more rounded tufts. In all these respects
it will be seen to resemble _S. aizoon_. It is a lovely form; the
sparkling teeth are relieved by the fine dark green ground of the
foliage.

These comb-leaved Saxifrages belong to the more neat and effective rock
plants; the type, at least, is of alpine origin, and under cultivation
it seems most happy amongst the stones. I have grown these kinds as pot
specimens, on nearly flat beds, and as edging plants; and in every
position they prove attractive. It is very strange that such pretty
forms are not more generally seen in gardens; they will grow well on
walls and the tops of outhouses, and are good subjects for town gardens.
Any kind of sandy soil will do for them; that of a vegetable character
is, however, the best; they may be planted with choicer things, for,
unlike many of the genus, they are not rampant growers. Practically,
they need no propagating; for as the specimens spread they make new
roots, and at any time one or half a dozen rosettes may be slipped off
for planting elsewhere. It is better, though, to avoid this with small
plants, as their full beauty is not realised until they become of
considerable size.
