Lamiales Lamiales is an order of flowering plants characterized by a wide range of life forms and economically important members. The group has been the focus of intensive research by botanists and institutions, and specimens are held in collections at museums and herbaria associated with universities. Studies by researchers at organizations such as the Royal Botanic Gardens, Kew, the Smithsonian Institution, and the New York Botanical Garden have clarified relationships within the order.

Description and diagnostic features

Members exhibit zygomorphic or actinomorphic corollas, often with bilabiate flowers, and show diverse vegetative morphologies examined by botanists at institutions like the Missouri Botanical Garden, the Natural History Museum, and the Field Museum. Diagnostic characters historically used in treatments by authors at the Botanical Society of America and the Linnean Society include ovary position, stamen number, and presence of iridoid compounds analyzed in laboratories affiliated with Harvard University, the University of Cambridge, and the University of California, Berkeley. Floral morphology has been compared in floras produced by the Royal Botanic Gardens, Kew, the Australian National Herbarium, and the Smithsonian Institution, with molecular markers assessed by research groups at the Max Planck Society, the Chinese Academy of Sciences, and the French National Centre for Scientific Research.

Taxonomy and classification

The order’s classification has been revised in systems promulgated by the Angiosperm Phylogeny Group, discussed in publications by authors associated with the Royal Botanic Gardens, Kew, the Natural History Museum, and the Missouri Botanical Garden. Historically, treatments appeared in works from the Linnean Society and the Botanical Society of America; more recent circumscription relies on molecular datasets produced by teams at the University of Oxford, the University of Göttingen, and the University of Chicago. Major taxonomic changes were debated at conferences organized by institutions like the International Botanical Congress, with syntheses published by Cambridge University Press and Oxford University Press.

Evolution and phylogeny

Phylogenetic hypotheses developed using DNA sequences from chloroplast and nuclear genes were generated by laboratories at the Max Planck Society, the Smithsonian Institution, and the University of California, Davis. Fossil evidence interpreted by paleobotanists at the Natural History Museum and the Field Museum has been integrated with molecular clock analyses performed by research groups at Stanford University, Yale University, and the University of Michigan. Evolutionary scenarios have been discussed in symposia at the Royal Society and in journals edited at Elsevier and Springer Nature, with contributions from researchers affiliated with the Chinese Academy of Sciences, Vanderbilt University, and the University of British Columbia.

Distribution and ecology

Species occur across continents documented in regional floras compiled by the Royal Botanic Gardens, Kew, the Australian National Herbarium, and the New York Botanical Garden. Ecological studies have been conducted in ecosystems monitored by the Smithsonian Tropical Research Institute, the World Wildlife Fund, and the Nature Conservancy, with fieldwork in locations managed by national parks such as Yellowstone National Park, Kruger National Park, and Banff National Park. Pollination biology investigations involved collaborations with researchers at the University of California, Santa Cruz, the University of Cape Town, and the University of São Paulo.

Diversity and notable families and genera

The order includes multiple families and genera treated in monographs published by academic presses including Cambridge University Press and the University of Chicago Press. Notable genera and families have been subjects of study by specialists affiliated with the Royal Botanic Gardens, Kew, the Missouri Botanical Garden, and the Smithsonian Institution, and are represented in databases maintained by institutions such as the Global Biodiversity Information Facility and the International Union for Conservation of Nature. Authors from the University of Edinburgh, the University of Helsinki, and the University of Tokyo have produced regional checklists and revisions highlighting diverse lineages within the order.

Economic and cultural importance

Numerous species are cultivated and economically important in industries overseen by agencies like the Food and Agriculture Organization, with ornamentals and medicinal plants featured in collections at botanical gardens including Kew, the New York Botanical Garden, and the Royal Botanic Garden Edinburgh. Ethnobotanical research conducted by teams at the Smithsonian Institution, the University of California, Los Angeles, and the University of Arizona documents traditional uses of taxa by communities studied in projects funded by organizations such as the National Science Foundation and the European Research Council. Conservation priorities involving threatened taxa are addressed by the International Union for Conservation of Nature, national agencies like the United States Fish and Wildlife Service, and NGOs including Conservation International.
