COCCOLOBA UVIFERA. 21 
The officinal portions are the leaves and the seeds. The leaves are collected when fully matured; they have an 
unpleasant narcotic odour, and nauseous, bitter taste. By drying, the odour is in a measure lost. The seeds are 
small, compressed, kidney-shaped, rough, blackish and without odour; they have a bitter, nauseous and acrid taste. 
These seeds are eaten by goats. 
The seeds have been analyzed by Brandes, who found an alkaloid principle, daturia, in combination with malic 
nat medical effects are those of a sedative narcotic; in over-doses it is poisonous. It is used to allay pain and 
produce sleep. It has also more or less alterative properties. It is used in substance, the leaves or seeds being given 
in powder, also in extract, tincture and ointment.

Essentiat Cuar.—F lowers occasionally unisexual, often in racemes. Calyz free, often coloured, imbricated in 
estivation. Stamens very rarely perigynous, usually definite, and inserted in the bottom of the calyx. Anthers dehis- 
cing lengthwise. Ovary free, usually formed by the adhesion of three carpels, one-celled, with a single erect ovule, 
whose foramen always points upwards. Styles or stigmas as many as the carpels of which the ovary consists. Ovule 
orthatropal. Nut usually triangular, naked, or protected by the calyx. Seed with farinaceous albumen, rarely with 
scarcely any. Embryo inverted, generally on one side, sometimes in the axis. Radicle superior, long. (Lindley, Veg. 
King.) These are herbaceous plants, rarely shrubs. The leaves are alternate, their stipules cohering round the stem; 
when young, rolled backwards, occasionally wanting. 
The medical properties of this tribe are astringent, and in some combined with purgative action. Many contain 
malic acid, in different parts.
