Botanical Description.--There are two forms of this variety in the Philippines, possessing the same properties and known by the same common name: _R. viridis_, Müll. (_R. communis_, Blanco) and _R. subpurpurascens_, Müll.; the former is the more common and has a glabrous, fistular stem. Leaves peltate, palmately cleft in 7 or 9 lobules, lanceolate, serrate. Petioles long. Flowers greenish, monoecious, the staminate ones in large panicled clusters below the pistillate. Filaments numerous, subdivided into several anther-bearing branches. Pistillate flowers, 3 sepals, 3 styles. Seed vessel, 3 prickly capsules, containing solitary seeds. The _R. subpurpurascens_ is distinguished from the former by bearing 2 glandules at the base of the leaves, the mulberry color of which latter suggests its common name, _Tangantangan na morado_, Tag., Vis. Habitat.--Very common in Luzon, Mindanao and other islands. URTICACEÆ. Nettle Family. _Artocarpus integrifolia_, Willd. Nom. Vulg.--_Nangka_, Tag.; _Jack Fruit Tree_, Eng. Uses.--The huge fruit of this tree is well known to the Filipinos and well liked by them as an article of food, eaten fresh or in sweet preserves. The arils and pulpy envelopes of the seeds are the parts eaten, also the seeds themselves, boiled or roasted. According to Padre Mercado the roasted seeds have an aphrodisiac action. The heated and powdered leaves are applied to wounds and given internally for congestions. The resin of the trunk is a useful application to ulcers and in India they give it internally to cure la melena, the dose, one "tola" mixed with the same amount of _manga_ resin and a little lime water. The same resin if heated makes an excellent cement for broken china. Botanical Description.--A tree, 20° or more in height, with abundant milky sap. Leaves alternate, oval, acute at both ends, slightly wavy and revolute borders, tough, glabrous and dark green upper surface; light green, slightly rough under surface. Petioles short. Flowers greenish, monoecious, growing on root, trunk and branches. Calyx very small, monophyllous, of about 7 deciduous lobules. Staminate: On a club-shaped receptacle, 3' or 4' long, bristling with the stamens; filaments very short, anthers 2-celled. Pistillate: On a common, oblong receptacle which ripens to the great fruit; style 1, short; rarely 2 divergent styles; stigmas acute.
