(fig), a genus of evergreen and, less commonly, deciduous trees and shrubs of the family Moraceae. There are some prostrate and climbing lianas; the latter climb by means of adventitious roots. Arboreal species reach 40 m in height and 3–5 m in diameter; they form massive roots at the base of the trunk. Many species, for example, the banyan (F. bengalensis), begin life as epiphytes and then form adventitious roots that reach the ground and proliferate into strong columnar supports for the massive crown. The aerial roots of certain epiphytic species strangle the host tree by entwining the trunk.

Fig leaves are usually entire; in some species they reach 60–70 cm in length. All parts of the plant contain a milky juice. The flowers, which have a reduced perianth, are small, usually unisexual, and complexly entomophilous. They develop on the internal surface of a spherical or pear-shaped hollow inflorescence that opens at the apex. The inflorescences form on the branches and on the trunks in the leaf axils. Pollination is performed by hymenopterons of the family Agaonidae. After fertilization a collective fruit, known as a syconium, develops. Each simple fruit of the syconium is dry and single-seeded; the walls of the syconium are either dry or juicy. The fruits of some species, for example, the common fig (F. carica) and the sycamore fig (F. sycomorus), are used as food.

There are more than 800 fig species, distributed in the tropics and, to a lesser extent, subtropics of both hemispheres. The plants are particularly widespread in the tropical rain forests of Southeast Asia, the Malay Archipelago, New Guinea, and the Solomon Islands. The milky juice of many species contains rubber, but it is not commercially valuable. The rubber plant (F. elastica), which is native to India and Burma and is raised as a houseplant, has a rubber content of as much as 30 percent.

Several fig species, including the common fig and the banyan, are hosts of the scale Tachardia lacca, an insect from which shellac is obtained.

MATERIALS AND METHODS: The two medicinal plants Acacia catechu (Katha in Manipuri) and Ficus hispida (Ashee heibong in Manipuri) were collected from different parts of Manipur during the period from March 2006 to February 2007 and processed in the laboratory to get the yield or extract as given below and also to determine the bactericidal effect on two known strains of Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922), as described in the Clinical Bacteriology by E.
