The Myrtales are an order of flowering plants in the malvid clade of the rosid group of dicotyledons. Well-known members of Myrtales include: myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, eucalyptus, crape myrtles, henna tree, pomegranate, water caltrop, loosestrifes, cupheas (cigar plants), evening primroses, fuchsias, willowherbs, white mangrove, leadwood tree, African birch, Koster's curse, and velvet tree.
Myrtaceae (/mərˈteɪsiˌaɪ, -siːˌiː/), 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 (i.e., without a toothed margin). 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.
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in 10 genera. The family includes the leadwood tree, Combretum imberbe. Three genera, Conocarpus, Laguncularia, and Lumnitzera, grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from Terminalia ivorensis. The commonly cultivated Quisqualis indica (as well as the entire former genus Quisqualis) is now placed in the genus Combretum. Many plants in the former Quisqualis genus contain quisqualic acid, a potent nerve toxin.
