Professor Rein thinks there are only three species of Pinus native of Japan, namely, P. densiflora, P. Massoniana, and P. parviflora. The two first are favorite trees of the Japanese, and are represented in lacquer and on porcelain ware, and living specimens are found in nearly all gardens. Some of the latter are curiously distorted, and from 200 to 500 years old, and they are regarded with an amount of veneration bordering on worship. Some of them have very long horizontal branches resting on the ground. P. Massoniana loves a sandy soil, is hardier, and perhaps rather larger than P. densiflora, and consequently more generally cultivated. It forms magnificent avenues, its rich dark green, long leaves being very beautiful. It attains a height of 100 feet, with a diameter of six feet. P. parviflora belongs to the group with five leaves in each sheath. It is widely dispersed in Japan, and reaches an altitude of 9000 feet, where it becomes shrubby. P. koraiensis is only cultivated in Japan. - Gardener's Chronicle.
