See Pastinaca silvestris. Banilia, Banilas. See Vanilla. Banksia. B. Abyssinica Bruce. The flowers are chiefly employed for ascarides in Abyssinia. A handful is infused in two quarts of beer. It is not the same plant with the banksia of the Supplementum Planta-rum, and has not yet found a place in botanical systems. Baobab, Bahobab. It is the adansonia bahobab Lin. Sp. Pi. 960, of the natural order malvaceae. The tree is the largest production of the whole vegetable kingdom. The trunk is not above twelve or fifteen feet high, but from sixty to eighty-five feet round. The lowest branches extend almost horizontally; and as they are about sixty feet in length, their own weight bends their extremities to the ground, and thus they form an hemispherical mass of verdure about one hundred and twenty, or one hundred and thirty feet in diameter. The centre root penetrates far into the earth; the rest spread near the surface.

The flowers are in proportion to the size of the tree; and are followed by an oblong fruit pointed at both ends, about ten inches long, five or six broad, covered with a kind of greenish down, under which is a rind, hard, and almost black, marked with rays which divide it lengthways into sides. This fruit hangs to the tree by a pedicle two feet long and an inch in diameter. It contains a whitish spongy juicy substance of an acid taste, and seeds of a brown colour and the shape of a kidney-bean, which are called goui. The pulp that surrounds these seeds is powdered when dry, and brought into Europe from the Levant, under the name of terra sigil-lata Lemnia. It grows on ths west coast of Africa, from the Niger to the kingdom of Belin.

The kernel of the fruit contains a large proportion of alkali when burnt, and the negroes mix it with palm oil to make soap.

The bark of this tree is called lalo; the negroes dry it in the shade, then powder and keep it in little cotton bags, and put two or three pinches into their food; it is mucilaginous, and powerfully prevents too violent perspiration.

The mucilage obtained from this bark is a powerful remedy against the epidemic fevers of the country that produces these trees; so is a decoction of the dried leaves. The fresh fruit is as useful as the leaves for the same purposes.
