The Lamiales are an order in the asterid group of dicotyledonous flowering plants. It includes about 23,810 species, 1,059 genera, and is divided into about 24 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.
Ophioglossum, the adder's-tongue ferns, is a genus of about 50 species of ferns in the family Ophioglossaceae. The name Ophioglossum comes from the Greek, and means "snake-tongue". The genus has the largest number of chromosomes in the known plant kingdom, but contrary to popular belief does not have the largest number of chromosomes out of all known organisms, falling short to the protist Oxytricha trifallax.
The Oleaceae are a family of flowering plants in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct. The extant genera includes Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The Oleaceae consist of shrubs, trees, and a few lianas. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members of the Oleaceae include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
Acanthaceae is a family of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests.
Bignoniaceae is a family of flowering plants in the order Lamiales commonly known as the bignonias. It is not known to which of the other families in the order it is most closely related.
The Verbenaceae are a family — the verbena family or vervain family — of mainly tropical flowering plants. It contains trees, shrubs, and herbs notable for heads, spikes, or clusters of small flowers, many of which have an aromatic smell.
Gesneriaceae, the African violet family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the Old World and New World (Gesnerioideae) tropics and subtropics, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.
Lentibulariaceae, the bladderwort family, is a family of carnivorous plants containing three genera: Genlisea, the corkscrew plants; Pinguicula, the butterworts; and Utricularia, the bladderworts.
Byblis is a small genus of carnivorous plants, sometimes termed the rainbow plants for the attractive appearance of their mucilage-covered leaves in bright sunshine. Native to western Australia, it is the only genus in the family Byblidaceae. The first species in the genus was described by the English botanist Richard Anthony Salisbury in 1808. Eight species are now recognized.
Phrymaceae, also known as the lopseed family, is a small family of flowering plants in the order Lamiales. It has a nearly cosmopolitan distribution, but is concentrated in two centers of diversity, one in Australia, the other in western North America. Members of this family occur in diverse habitats, including deserts, river banks and mountains.
Pedaliaceae, the pedalium family or sesame family, is a flowering plant family classified in the order Scrophulariales in the Cronquist system and Lamiales in the Angiosperm Phylogeny Group system. Cronquist included the family Martyniaceae in Pedaliaceae, but phylogenetic studies have shown that the two families are not closely related and they are maintained as separate by the APG. Both families are characterized by having mucilaginous hairs, which often give the stems and leaves a slimy or clammy feel, and often have fruits with hooks or horns.
Calceolariaceae is a family of flowering plants in the order Lamiales that has been recently segregated from Scrophulariaceae. The family includes three genera, Calceolaria, Porodittia, and Jovellana, but analysis suggests that the monotypic Porodittia should be placed within Calceolaria. Recent molecular phylogenies that included Calceolaria have shown not only that this genus does not belong in Scrophulariaceae but also that it is the sister clade to the majority of the other families of the Lamiales. Morphological and chemical characters also support the separation of Calceolariaceae from Scrophulariaceae and other Lamiales. Some recent studies have supported a sister-group relationship between Calceolariaceae and Gesneriaceae. Given this close relationship, some authors opt to merge this family into Gesneriaceae as subfamily Calceolarioideae
Martyniaceae is a family of flowering plants in the Lamiales order that are restricted to the New World. The family was included in Pedaliaceae in the Cronquist system but is recognized as a separate family by the Angiosperm Phylogeny Group on the basis of phylogenetic studies that show that the two families are not closely related. Both families are characterized by having mucilaginous hairs — which give the stems and leaves a slimy or clammy feel — and fruits with hooks or horns. Some members of the genus Proboscidea are known as "unicorn plant" or "devil's claw" because of their horned seed capsules.
Nepenthes khasiana is an endangered tropical pitcher plant of the genus Nepenthes. It is the only Nepenthes species native to India. It is thought to attract prey by means of blue fluorescence.
Digitalis lanata is a species of foxglove. It gets its name due to the texture of the leaves. Digitalis lanata, like some other foxglove species, is toxic in all parts of the plant. Symptoms of digitalis poisoning include nausea, vomiting, severe headache, dilated pupils, problems with eyesight, and convulsions at the worst level of toxicity. The plant is also harmful to other animals. In some cases it is considered invasive or a noxious weed. Minnesota is one of the few places that consider it invasive as noted by the Western Weed Society. It is in leaf all year, in flower in June and July, and the seeds ripen in early-mid September. The flowers are hermaphroditic. Bees pollinate the flowers.
Cotula is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds.
Linderniaceae is a family of flowering plants in the order Lamiales, which consists of about 13 genera and 195 species from worldwide, mainly in neotropics.
The Carlemanniaceae are a tropical East Asian and Southeast Asian family of subshrub to herbaceous perennial flowering plants with 2 genera. Older systems of plant taxonomy place the two genera, Carlemannia, and Silvianthus within the Caprifoliaceae or the Rubiaceae. The Angiosperm Phylogeny Group classification of 2003 places the group in the Lamiales, as a plant family more closely related to the Oleaceae than to the Caprifoliaceae.
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system.
Carlemannia is a genus of flowering plants in the family Carlemanniaceae, found in Nepal, the eastern Himalaya, Assam, Tibet, south-central and southeast China, Indochina, and Sumatra. Basal in their lineage, which is now thought to be the Lamiales, they have a chromosome count of 2n=30.
