Anonaceæ.

Custard-Apple Family.

Artabotrys odoratissimus, R. Br. (A. hamatus, Bl.; Uvaria Sinensis and Unona uncinata, Blanco.)

Nom. Vulg.—Ilag̃-ilag̃ de China, Sp.-Fil.; Alag̃-ilag̃ Son-son, Tag.

Uses.—A decoction of the leaves of this species is used to treat cholera in some of the islands of the Malay group; in the island of Java they use for the same purpose a decoction of the leaves of the species A. suaveolens, Bl., which is commonly called Susog̃ Damulog in the Pampanga dialect. The active principles of these plants are so powerful that one must beware of giving a large dose, as hemorrhages, nervous phenomena and abortion may follow.

Botanical Description.—A tree 15–18° high with leaves alternate, lanceolate, glabrous, and petioles very short. Flowers very sweet, axillary, solitary. Petals 6, fleshy, concave at the base. Stamens indefinite, closely packed, overlapping. Peduncle curved like a crook.

Habitat.—Cultivated in gardens.

Anona squamosa, L. (A. tuberosa, Rumph.)

Nom. Vulg.—Ates, Tag.; Custard Apple, Eng.

Uses.—The fruit of the mature ates is edible and is one of the most delicious that grows in the Philippines; its white and delicately perfumed pulp has a delicious flavor. The unripe fruit is exceedingly astringent. The fermented juice of the ripe pulp is used in certain parts of America to prepare a popular drink. The powdered seeds make a useful parasiticide especially when used on the scalp, but it is necessary to avoid getting any of the drug in the eyes on account of its irritant effect.

Botanical Description.—Tree 8 or 9° high with leaves alternate, oblong, the edges pubescent. Flowers greenish-yellow, axillary, solitary; peduncle not curved. Petals 6, convergent. Stamens crowded, indefinite. Fruit fleshy, covered with scales or rather rounded tubercles; beneath is the white and fragment pulp, covering the long-oval seeds.

A. reticulate, L.

Nom. Vulg.—Anonas, Sp.-Fil.

Uses.—The fruit of this species is neither as much prized nor as abundant in the Philippines as that of the ates. When unripe it possesses the same properties as the latter. The large proportion of tannin which both species contain in their unripe state, makes them very useful in treating diarrhœa and dysentery. They are administered in the form of a decoction, by enema. The sap of the trunk is very irritating. The roots are used by the American Indians to treat epilepsy. Lemon juice is the antidote for the sap of this species.

I wish to call attention to the similarity of the common name of this plant to another entirely distinct species commonly used in the Tagalo therapeutics; namely, the anonag̃ (Cordia), with which it must not be confused.

Botanical Description.—Tree 10° high with leaves lanceolate, pubescent. Flowers in a sort of umbel. Corolla like that of A. squamosa. Fruit without the plainly visible tubercles of the foregoing species, their presence being merely suggested by a sort of net traced on the surface.

A. muricata, L.

Nom. Vulg.—Guanábano, Goyabano, Sp.-Fil.

Uses.—The ripe fruit possesses antiscorbutic properties; the unripe fruit is used in treating dysentery. It is said that the ripe fruit is used in diseases of the liver.

Botanical Description.—Tree with leaves oval, alternate and glabrous. Flower solitary, terminal, whitish. The fruit is much larger than that of the other species, is covered with scales that end in a soft point or thorn and has a very pronounced acid taste.

Habitat.—All three species are common in all parts of the Archipelago.
