Australia. An evergreen shrub, bearing
countless, minute, white flowers. Sprays, if cut when the flowers are
fully expanded, will retain their decorative qualities for a year. It is
common in the south-west, and at Trewidden there are bushes 8 feet in
height.

PAULOWNIA IMPERIALIS.--Japan. A hardy deciduous flowering tree, bearing
erect panicles of large, lilac, gloxinia-like flowers. Owing to the
spring frosts, it rarely perfects these except in sheltered sites in
mild springs, but when in good bloom it is marvellously beautiful.

PENTSTEMON CORDIFOLIUS.--California. A tall-growing species, bearing
bright-scarlet flowers in the summer. With the shelter of a wall it
grows to a height of 5 feet or more. Trewidden.

PHILESIA BUXIFOLIA.--Chili. A dwarf evergreen shrub, rarely exceeding 2
feet in height, bearing drooping, pink lapageria-like blossoms. To be
found in many gardens.

PHOTINIA JAPONICA.--Japan. The Loquat. This hardy, ornamental-foliaged
tree is practically hardy, and at Enys flowers annually. We believe,
however, that it has not fruited. The finest specimen we know of, 15
feet in height with a head 12 feet through, is at Saltram.

PIERIS FORMOSA.--Himalayas. This so-called Andromeda is widely met with.
The finest example is at Pentillie Castle, and is 20 feet in height with
a spread of 30 feet. When this is white with its clustering
flower-sprays it is a lovely sight.

PIMELEA DECUSSATA.--Australia. An evergreen shrub, bearing rose-red,
globular flower-heads at the extremities of the branches. Tresco.

PINUS MONTEZUMAE.--Mexico. A noble and distinct Pine, good specimens of
which are at Tregothnan and Menabilly, where it has fruited.

PIPTANTHUS NEPALENSIS.--Nepaul. An evergreen shrub, bearing numbers of
bright-yellow laburnum-like flowers. It seems indifferent to soil, and
may be seen flourishing under adverse circumstances. Common.

PLAGIANTHUS BETULINUS.--New Zealand. Ribbon tree. Bears small white
flowers in clusters. A splendid example 50 feet in height is at
Abbotsbury.

PITTOSPORUM.--New Zealand. Evergreen shrubs. _P. Mayi_, at Tregothnan,
is about 30 feet in height; while we have seen _P. bicolor_ over 20
feet, and many fine examples of _P. undulatum_, _P. tenuifolium_, of
which last a hedge has been made at Falmouth, and other species. All
bear their little flowers in profusion in the south-west. The Japanese
_P. Tobira_ is a hardy shrub, bearin
