The broad coriaceous leaves, ending in two cartilaginous points of unequal size, and pectinately arranged, are characteristic of this species, which when once seen, can scarcely be confused with any other.

Abies holophylla, Maximowicz,' which has been identified by Dr. Masters with A. firma, is considered by Komarov,? the latest observer, to be a distinct species. It differs in the leaves not being bifid, and also in the bracts of the cone, which are short, scarcely extending more than one-third the length of the scale. This species, according to Komarov, attains 150 feet high, and grows in mountain woods at elevations not exceeding 1800 feet above sea-level, in the Manchurian provinces of Ussuri, Kirin, and Mukden, and also in northern Korea. It was introduced into cultivation in Russia by Komarov, who sent seeds in 1898.

Other specimens of Abies from the Chinese provinces of Hupeh, Shensi, and Yunnan* have also been considered by Dr. Masters to be A. firma; but this identification is doubtful. (A.H.)

This, the best known fir in Japan, is widely distributed in the south, and, according to Mayr, does not extend north of lat. 40°, and attains perfection in the warm sub-tropical provinces of Kii, Shikoku, and Kiusiu. It is very commonly planted in temple grounds and parks, but few of these specimens looked as if the isolated situation agreed with them; and wherever | saw the tree growing naturally, it was scattered among deciduous trees and other conifers in more or less shady places in the forest. It grows to a great size in the sheltered valleys and moist, deep soils of the central and southern provinces. I measured one at Myanohara, on the Nakasendo road near Wada, which was 135 feet by 16 feet, but this tree was dying at the top, and may have been planted or have been a natural seedling in a temple grove. Another in the forest near the entrance to Koyasan was about 120 feet high by 15 feet 9 inches in girth, but the average size of the mature trees that I saw was not over 100 feet by 9 feet. A third, growing close to a temple at Narai (Plate 216), measured 125 feet by 11½ feet. As the timber is of little value except for packing- cases, tea-boxes, and pulp-wood, the tree is not much planted at the present time except for ornament. It reproduces itself freely from seed whenever the conditions are suitable, and its large greenish-yellow cones are fully formed in August.

According to Rein* its natural habitat is from 1000 to 1500 metres, but though this may be the case in the southern island, I should say it was too high for the central provinces, as in Kisogawa I saw it much lower, and I do not think it there reaches 4000 feet.

This species was introduced into Europe in 1861 by J. Gould Veitch,® but has never become common in cultivation, though it seems to be hardy even in some parts of Scotland. It undoubtedly requires a warm, moist climate to bring it to
