(botany) An order of dicotyledonous plants in the subclass Rosidae characterized by opposite, simple, entire leaves and perigynous to epigynous flowers with a compound pistil.
An order of flowering plants in the core eudicots. The order consists of 10 families and approximately 9300 species. The two largest families are Melastomataceae (approximately 4500 species) and Myrtaceae (approximately 3000 species). Thymelaeaceae are excluded in recent concepts of the order, being related instead to families of Malvales.
Myrtales are chiefly tropical, but Onagraceae and Penaeaceae are predominantly temperate. Myrtales usually have opposite, simple, entire leaves and perigynous to epigynous flowers with a compound pistil and most commonly axile placentation. The seeds have little or no endosperm. The stamens are normally numerous, and many species have tetramerous flowers. Vascular bundles characteristically have internal phloem, which is otherwise rare in the rosid dicots.
Economic crops in Myrtaceae include spice trees such as allspice (Pimenta) and cloves (Syzygium), and the timber trees Eucalyptus. Other important economic crops in the order include evening primrose (Oenothera, Onagraceae) and pomegranate (Punica, Lythraceae). Purple loosestrife (Lythrum salicaria) can be a noxious weed of North American waterways. See also Eudicotyledons.
