Mammea-Tree: A genus of the monogynia order, belonging to the polyandria class of plants; and in the natural method ranking with those of which the order is doubtful. The corolla is tetrapetalous; the calyx diphyllous; the berry very large and tetraspermous. There are two species; both of them large evergreen trees of the hot parts of America and Asia, and retained here in hot-houses for variety; both of them adorned with large, oval, oblong, stiff leaves, and large quadripetalous flowers, succeeded by large round eatable fruit of a most exquisitely rich flavour. They are propagated by seed, which is to be sowed in small pots of light earth, and plunged in the bark-bed, where they will soon come up; give gentle waterings, and about August transplant them into separate pots a size larger, plunging them into the bark-bed, and giving shade and water till fresh-rooted. In this country they must never be taken out of the stove.
