Myrtaceae
The 'Myrtaceae' or 'Myrtle family' are a family of dicotyledon plants, placed within the order Myrtales. Myrtle, clove, guava, feijoa, allspice, and 'Eucalyptus' belong here. All species are woody, with essential oils, and flower parts in multiples of four or five. One notable character of the family is that the phloem is on both sides of the xylem, not just outside as in most other plants. 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 colored, and there are many of them.
