ings are most irregular, as striped, flecked, marbled, dotted,
and edged; the various shades of green blended with pink and white,
although figured on one of the commonest plants we know, render such
plant worthy of a place in every garden, and more especially on
rockwork.

It has this drawback--it is not constant. In some gardens the markings
die out. This, however, need not be, for a rather dry situation and rich
soil will produce rosettes of large size and good figuring. Still, there
will be fully half of the rosettes entirely green in a large patch; this
is more desirable than otherwise. The marked ones have a more starry
effect in such a green setting; it is only when all become green that
disappointment is felt. Sometimes I have noticed rosettes, about the
size of a penny-piece, all one colour--creamy-white--which, when cut
from the plant, very much resembled a carnation. Such abnormal forms are
of no moment to the botanist, but if nine out of every ten persons who
see this plant are interested, not to say pleased with it, it ought not
to be entirely neglected. It is most effective in patches 1ft. to 2ft.
broad. In propagating it the more finely marked pieces only should be
taken.

Flowering period, May to July.

Saxifraga Wallacei.

_Nat. Ord._ SAXIFRAGACEAE.

A hardy perennial hybrid variety, of first-class merit. Its loose and
spreading panicles of large pure white flowers are something better than
the ordinary run of bloom belonging to this extensive genus; it is said
to be the offspring of species of the mossy section; but there is
certainly a great likeness about its foliage to some of the horny
section, such as _S. cornutum_ or _S. pentadactylis_, or even the
handsome _S. geranioides_. It would, however, be hard to say what it is
from; but in it we have not only a showy but most useful variety (see
Fig. 93). It has deservedly grown into great favour, though known to
amateurs but for three years. It begins to flower in April, but in May
it is in its best form, being covered with a rich mass of bloom from the
foliage to the height of a foot.

The flowers, as before stated, are of a pure white--an unusual colour
amongst the genus; they are bell-shaped but erect, the ovate petals
reverse. Well-grown specimens with me have flowers quite an inch across.
The individual blooms last more than a week, and the succession is well
maintained during summer. The panicles are leafy, having small entire
leav
