Overview

[ Back to top ]

Lamiales is an order in the asterid group of dicotyledonous flowering plants. It includes approximately 11,000 species divided into about 20 families. Well-known or economically important members of this order include lavender, lilac, olive, jasmine, the ash tree, teak, snapdragon, sesame, psyllium, garden sage, and a number of table herbs such as mint, basil, and rosemary.

Taxonomic history

[ Back to top ]

Lamiales formerly had a restricted circumscription (e.g., by Arthur Cronquist) that included the major families Lamiaceae (Labiatae), Verbenaceae, and Boraginaceae plus a few smaller families. Recent phylogenetic work has shown that Lamiales is polyphyletic with respect to order Scrophulariales and the two groups are now usually combined in a single order that also includes the former orders Hippuridales and Plantaginales. Lamiales has become the preferred name for this much larger combined group. The placement of Boraginaceae is unclear but phylogenetic work shows that this family does not belong in Lamiales.

Also, the circumscription of family Scrophulariaceae, formerly a paraphyletic group defined primarily by plesiomorphic characters and from within which numerous other families of the Lamiales were derived, has been radically altered to create a number of smaller, better-defined and putatively monophyletic families.

Rubiales

Rubiales was an order of flowering plants in the Cronquist system, including the families Rubiaceae and Theligonaceae. The latest APG system (2009) does not recognize this order and places the families within Gentianales. [more]

Scrophulariales

Lamiales is an order in the asterid group of dicotyledonous flowering plants. It includes approximately 11,000 species divided into about 20 families. Well-known or economically important members of this order include lavender, lilac, olive, jasmine, the ash tree, teak, snapdragon, sesame, psyllium, garden sage, and a number of table herbs such as mint, basil, and rosemary.

Solanales

The Solanales are an order of flowering plants, included in the asterid group of dicotyledons. Some older sources used the name Polemoniales for this order. [more]

At least 24,293 species and subspecies belong to the Order Solanales.
