Myrtaceae
Encyclopedia
The Myrtaceae or Myrtle family are a family of dicotyledon
plant
s, placed within the order Myrtales
. Myrtle, clove
, guava
, feijoa
, allspice
, and eucalyptus
belong here. All species are woody, with essential oil
s, and flower parts in multiples of four or five. One notable character of the family is that the phloem
is located on both sides of the xylem
, not just outside as in most other plants. The leaves
are evergreen
, alternate to mostly opposite, simple, and usually with an entire (not toothed) margin. The flower
s have a base number of five petals, though in several genera the petals are minute or absent. The stamen
s are usually very conspicuous, brightly coloured and numerous.

Historically, the Myrtaceae were divided into two subfamilies. Subfamily Myrtoideae (ca. 75 genera) was recognized as having fleshy fruits and opposite, entire leaves. Most genera in this subfamily have one of three easily recognized types of embryos. The genera of Myrtoideae can be very difficult to distinguish in the absence of mature fruits. The Myrtoideae are found worldwide in subtropical and tropical regions, with centres of diversity in the Neotropics, northeastern Australia, and Malesia.
In contrast, Subfamily Leptospermoideae (ca. 80 genera) were recognized as having dry, dehiscent fruits (capsules) and leaves arranged spirally or alternate. The Leptospermoideae are found mostly in Australasia, with a centre of diversity in Australia. Many genera in Western Australia have greatly reduced leaves and flowers typical of more xeric habitats.
The division of the Myrtaceae into the Leptospermoideae and Myrtoideae was challenged by a number of authors, including Johnson and Briggs (1984), who identified 14 tribes or clades within the Myrtaceae, and found the Myrtoideae to be polyphyletic. Molecular studies by several groups of authors, as of 2008, have confirmed that the baccate (fleshy) fruits evolved twice from capsular fruits, and as such the two subfamily classification does not accurately portray the phylogenetic (= evolutionary) history of the family. Thus many workers are now using a recent analysis by Wilson et al. (2001) as a starting point to test further analyses of the family.
The genera Heteropyxis
and Psiloxylon
have been separated as separate families by many authors in the past as Heteropyxidaceae and Psiloxylaceae. However, Wilson et al. (2001) included Heteropyxis and Psiloxylon in Myrtaceae. These two genera are presently believed to be the earliest arising and surviving lineages of Myrtaceae.
Many new species are being described annually from throughout the range of Myrtaceae. Likewise, new genera are being described nearly yearly.
