Eugenia is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the northern Andes, the Caribbean, and the Atlantic Forest (coastal forests) of eastern Brazil. Other centers of diversity include New Caledonia and Madagascar. Many of the species that occur in the Old World have received a new classification into the genus Syzygium . [3]

Contents

All species are woody evergreen trees and shrubs. Several are grown as ornamental plants for their attractive glossy foliage, and a few produce edible fruit that are eaten fresh or used in jams and jellies.

Taxonomy

The genus was named in honor of Prince Eugene of Savoy. [4]

Many species new to science have been and are in the process of being described from these regions. For example, 37 new species of Eugenia have been described from Mesoamerica in the past few years.[ when? ] At least 20 new species are currently[ when? ] in the process of being described from New Caledonia, and approximately the same number of species new to science may occur in Madagascar.[ citation needed ] Despite the enormous ecological importance of the myrtle family in Australia (e.g. Eucalyptus , Corymbia , Angophora , Melaleuca , Callistemon , Rhodamnia , Gossia ), only one species of Eugenia, E. reinwardtiana , occurs on that continent. The genus also is represented in Africa south of the Sahara, but it is relatively species-poor on that continent. In the past some botanists [ which? ] included the morphologically similar Old World genus Syzygium in Eugenia, but research by Rudolf Schmid in the early 1970s convinced most botanists that the genera are easily separable. Research by van Wyk and colleagues in South Africa suggests the genus may comprise at least two major lineages, recognizable by anatomical and other features.[ citation needed ]

Molecular phylogenetic studies have changed the historical circumscription of the genus. Many species formerly placed in Eugenia have been moved to Syzygium . [5] Two others have been reassigned to Pimenta. [6] The Caribbean genera Hottea, Calyptrogenia and Pseudanamomis were shown to be embedded in Eugenia. [7] The monotypic Indian genus Meteoromyrtus was also found to be part of Eugenia. [8]

Ecology

Eugenia species are sometimes used as food plants by the larvae of hepialid moths of the genera Aenetus (including A. splendens ) and Endoclita (including E. damor and E. malabaricus ). Aenetus species burrow horizontally into the trunk then vertically down. Other Lepidoptera larvae which feed on Eugenia include Eupseudosoma aberrans and the snowy eupseudosoma.

<span class="mw-page-title-main">Myrtaceae</span> Myrtle family of plants

Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous.

<i>Syzygium</i> Genus of plants

Syzygium is a genus of flowering plants that belongs to the myrtle family, Myrtaceae. The genus comprises about 1200 species, and has a native range that extends from Africa and Madagascar through southern Asia east through the Pacific. Its highest levels of diversity occur from Malaysia to northeastern Australia, where many species are very poorly known and many more have not been described taxonomically. One indication of this diversity is in leaf size, ranging from as little as a half inch to as great as 4 ft 11 inches by sixteen inches in Syzygium acre of New Caledonia.
