ens, seedlings, and therefore to keep the true
type, it must be increased by cuttings. If frost cuts the stems down in
winter, new growths spring up in the following year. Its graceful flower
masses are useful in the house. _P. molle_ is not unlike it.

PRUNUS TRILOBA is an excellent wall shrub (see illustration).

[Illustration: _PRUNUS TRILOBA AGAINST SUNNY WALL AT KEW._]

PUNICA (Pomegranate).--Both single and double.

PYRUS.--The Pyruses are described elsewhere in this book. _P. (Cydonia)
japonica_ and its many beautiful varieties, and _P. Maulei_ are,
however, more frequently grown against walls than any other members of
the same family. _Prunus triloba_ is an excellent wall shrub.

RAPHIOLEPIS OVATA.--A very handsome plant.

ROSA (Rose) (see p. 342).

RUBUS (see p. 450).

SMILAX.--This group is not common in gardens, but is interesting. They
are a change from the repetition of a few common things. _S.
rotundifolia_ is a very handsome large-leaved Smilax with shiny foliage,
now and then met with as _S. laurifolia_ or _S. latifolia_, from which,
however, according to Mr. R. Irwin Lynch, of Cambridge, it is distinct.
All the kinds of hardy Smilax form handsome leafy creepers for walls,
but in our climate they rarely produce the rich clusters of red berries
that often render them so attractive abroad.

SOLANUM.--_S. jasminoides_ is the most popular flowering climber of the
south-west, producing its white bloom-clusters for many months in
succession. It is classed as deciduous in botanical dictionaries, but is
rarely bare of leaves, except after severe frosts in the early months of
the year. _S. crispum_ and _S. Wendlandi_ will also succeed in mild
counties; the latter has very large bluish flowers.

STAUNTONIA LATIFOLIA (syn. _Holboellia latifolia_).--This plant bears
clusters of small greenish-white, highly-fragrant flowers in March, and
often perfects seed-pods in the autumn. It is a rapid grower, and its
leathery leaves are rarely affected by frost.

STUARTIA PSEUDO-CAMELLIA.--A rare and very beautiful flowering shrub now
seldom seen in even the best of gardens. It is a native of Japan, the
flowers being ivory white and perfectly cup-shaped, somewhat like a
single White Camellia. _S. pentagyna_ comes from North America, as also
_S. virginica_, but the first-named is the finest and is worth a good
deal of trouble to grow well. Planted in loam and peat and sand at the
foot of a sunny and sheltered wall, t
