An order of flowering plants, division Magnoliophyta (Angiospermae), in the subclass Rosidae of the class Magnoliopsida (dicotyledons). The order Apiales (also known as the Umbellales) includes two major families: the Apiaceae, with about 3500 species; and the Araliaceae, with about 700 species. There are also 5 minor families, including the family Pittosporaceae, which contains more than 200 species of evergreen trees and shrubs. In general, members of the Apiales are herbs or woody plants with mostly compound or conspicuously lobed or dissected leaves, well-developed schizogenous secretory canals, separate petals, and an inferior ovary that has only one ovule in each locule. The nodes are generally multilacunar, and the pollen is trinucleate. See also: Dicotyledons; Magnoliophyta; Magnoliopsida; Plant kingdom; Rosidae
