The order Lamiales is a taxon in the asterid group of dicotyledonous flowering plants. It includes approximately 11,000 species divided up into about 10 families. Well-known members of this order include the lavender, the lilac, the olive, the jasmine, the ash tree, the teak, the snapdragon, and a number of table herbs such as mint, basil, and rosemary.
in this order typically have the following characteristics, although there are exceptions to all of them:
Lamiales formerly had a restricted circumscription (e.g., by Arthur Cronquist
) that included the major families Lamiaceae
, 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
. 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.
