2. EUGENIA L.
Trees or shrubs, with hard durable wood and scaly bark. Flowers often large and conspicuous, on short bibracteolate pedicels, in axillary racemes or fascicles or dichotomously branched cymes, with minute caducous bracts and bractlets; calyx campanulate, scarcely produced above the ovary, the limb 4 or rarely 5-lobed; petals usually 4, free and spreading; ovary 2 or rarely 3-celled; ovules numerous in each cell, semianatropous. Fruit 1—4-seeded. Seeds globose or flattened; seed-coat membranaceous or cartilaginous; embryo thick and fleshy; cotyledons thick, more or less conferruminate into a homogeneous mass; radicle very short, turned toward the hilum.
Eugenia with some five hundred species is common in all tropical regions, with eight species reaching the shores of southern Florida, of these 6 are small trees. Several species are valued for their stimulant and digestive properties; some produce useful timber or edible fruit, and others are cultivated for the beauty of their flowers. Cloves are the flower-buds of Eugenia aromatica Baill., a native of the Molucca Islands; and Eugenia Jambos L., the Rose Apple, of southeastern Asia, is cultivated in all tropical countries as a shade-tree and for its delicately fragrant fruit.
The generic name commemorates the interest in botany and gardening taken by Prince Eugène of Savoy, who built the Belvidere Palace near Vienna in the beginning of the eighteenth century, and made a collection of rare plants in its gardens.
