The Guava is an extensive genus of low-growing evergreen trees, found chiefly in the West Indies, South America, and China. They have become naturalized in Hawaii, and may be found growing wild on waste lands and by the roadside. In some localities growing so rank as to become troublesome. The leaves are oval to oblong, usually acuminate, glabrous above and pubescent beneath, and have prominent veins. The fragrant, white, solitary flowers are axillary. The somewhat rough skin of the globose fruit is a brownish-yellow, and the firm, dark-pink pulp, in which is embedded numerous seeds, is generally acid and aromatic. This guava is the source of the famous guava jelly of commerce. [Illustration: PLATE LVII.--_Psidium Guayava pomiferum_ (_common guava_). One half natural size.] _G. P. W. Collection._ PLATE LVIII _Psidium Guayava._ (Sweet red guava.) This guava has the same general characteristics as the preceding variety. It is more frequently found in valleys and gulches than in the open. Its red pulp is firm and sweet. [Illustration: PLATE LVIII.--_Psidium Guayava_ (_sweet red guava_).] _G. P. W. Collection._ PLATE LIX _Psidium Guayava._ (White lemon guava.) The lemon guava tree grows taller and somewhat more erect than the others. The pear-shaped fruit is large, often 3 inches in length. It has a rough, greenish-white skin, and the white pulp is sweet. This is a cultivated variety, and is found growing in a few gardens in these Islands.

This handsome evergreen tree was an early introduced species, and now is very common about the islands. Grows very symmetrically, and attains the height of 20 to 25 feet. Leaves, small, lanceolate, shiny, the trunk and branches smooth. Flowers white and very fragrant; fruit small, pear-shaped, pulp yellow and containing many seeds; this species is very prolific, but the fruit is inferior.

One of the hardiest of the guavas, and said to be a native of Brazil. The date of its introduction to Hawaii is not recorded, and as Hillebrand makes no mention of it, it is probably of recent importation. A shrubby tree 15 to 20 feet high. Leaves opposite, obovate, small, leathery, dark-green, shiny. Flowers white, fragrant. Fruit spherical, about one inch in diameter, purple-reddish when ripe, soft, juicy pulp, which has an agreeable flavor, and containing many small seeds. This fruit is used for making jams and jellies, and bears a crop more or less during all the months of the year. [Illustration: PLATE LXI.--_Strawberry Guava._ One half natural size.] _G. P. W.
