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 Montezumæ.—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, bearing spreading flower-heads of fragrant white blossom.
