This deciduous tree is said to be a native of the Society Islands, and is common to the tropics of both hemispheres. It is a large, spreading and graceful tree, reaching a height of from 30 to 50 feet. Its pinnate leaves are green and glossy; the leaflets are oval-oblong and opposite. The foliage is shed from December until April. The flowers are paniculate, small, and greenish-white. The fruit, which ripens from November until April, is a fleshy drupe, oval in shape, from 1 to 3 inches in diameter; it has a thin, smooth, golden-yellow skin, which has a rather sour disagreeable odor. The fleshy pulp is light yellow, is mellow when quite ripe, and has a sub-acid delicious flavor, compared by some to the pineapple. Within this pulp is embedded a 1 to 5 loculed, bony endocarp, which contains generally one seed. This endocarp is covered with fibres which penetrate the pulp. The first Wi tree in Hawaii was planted at the residence of Mr. John S. Walker, Nuuanu Valley. [Illustration: PLATE XXVI.--_Spondias dulcis._ One third natural size.] _G. P. W. Collection._ PLATE XXVII _Spondias lutea._ HOG PLUM. This tree is distributed over Tropical America, West Africa and Java, where it is commonly called the Hog Plum, and is used for fattening swine. In Jamaica it grows well, up to an elevation of 4000 feet. It is a large, graceful tree, about 50 feet high, with spreading branches, and it is particularly beautiful when in fruit. The pinnate leaves are a clear green, the leaflets are ovate-lanceolate, and the golden-yellow fruit hangs in clusters. It ripens in September and October. The fruit is ovoid, about 1 inch long; it has a smooth skin, having a disagreeable odor. There is one large seed, which resembles the husk of a ground-nut. This fruit is cooling and aromatic. To my knowledge there are but two trees of this kind in bearing in the Hawaiian Islands, and these are growing in private grounds in Honolulu.

The Mammee Apple, which grows well in Hawaii, is a native of the West Indies, and is a fruit much esteemed in tropical countries. In Jamaica it thrives well, up to an elevation of 3000 feet. The tree attains a height of from 30 to 40 feet, and the wood, which is beautifully grained, is durable and well adapted to building purposes. Its leaves are rigid and leathery. The round seeds, varying in number from 1 to 4, germinate freely, and the young plants are easily raised. The fruit is from 3 to 6 inches in diameter, is brown or russet color, and has a yellow pulp, which is sweet and aromatic. The outer rind, as well as the pulp immediately surrounding the seeds, is very bitter. The fruit may be eaten raw, and is very delicious when preserved.
