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.
PODOCARPUS ANDINA.--Chili. A handsome evergreen tree to be found in most gardens. At Penjerrick there is a specimen 40 feet in height.
POINCIANA (CÆSALPINA) GILLIESI.--South America. An evergreen shrub with acacia-like foliage, bearing clusters of large yellow flowers with bright-red stamens. Mr. Fitzherbert says, "The finest specimen I have seen was in the late Rev. H. Ewbank's garden at Ryde, but I know of smaller ones in the south-west."
POLYGALA GRANDIFOLIA (syns. _grandis_, &c.).--Bahia. An evergreen flowering shrub, the finest of its race, bearing large rose and white flowers. Tregothnan.
PSEUDOPANAX CRASSIFOLIUM.--New Zealand. An evergreen shrub with dark-green thick leaves 2 feet in length, with orange midribs. Ludgvan Rectory.
PUNICA GRANATUM.--The Pomegranate is a neglected shrub in English gardens. Planted at the foot of a south wall, and treated generally like a well-groomed Peach tree, it will flower from June to September. It is not a shrub for cold climates, but Mr. Watson, writing in the _Garden_, October 26, p. 283, says, "At Kew three varieties are grown outdoors, namely, the type, the big double-white flowered variety, with petals margined with white, Picotee-like, and the dwarf variety known as Nana. There are other forms beside these, including a white-flowered one which I have seen in Paris gardens, where old--very old--standard plants are grown and treasured. The dwarf variety is cultivated as a pot plant in some continental countries. I have seen it in the Hamburg florists' shops, pretty little pyramids in 5-inch pots, covered with flowers. Fruits are rarely produced by the Pomegranate in England."
