Crassulaceae

Crassulaceae is a family of succulent flowering plants with global significance in horticulture, biogeography, and physiological research. Members of the family have been subjects in studies linked to Charles Darwin, Joseph Dalton Hooker, Gregor Mendel, Alexander von Humboldt, and institutions such as the Royal Botanic Gardens, Kew, Missouri Botanical Garden, and Smithsonian Institution. The family has influenced botanical works including publications from the Linnean Society of London, the Royal Society, the American Society of Plant Taxonomists, and various regional floras like the Flora Europaea and Flora of China.

Description

Crassulaceae comprises herbaceous succulents and shrubs noted for water-storing leaves and CAM photosynthesis, traits central to studies by researchers at University of Cambridge, Harvard University, University of California, Berkeley, University of Oxford, and University of Tokyo. Classic taxa such as members cultivated at the Kew Gardens and displayed in the United States Botanic Garden illustrate leaf succulence and clustered inflorescences referenced in monographs from the Royal Horticultural Society and the Missouri Botanical Garden Press. Descriptions of species appear in regional checklists produced by institutions like the South African National Biodiversity Institute, Australian National Herbarium, and the New York Botanical Garden.

Taxonomic treatments of the family involve genera long discussed in literature from the International Botanical Congress, Angiosperm Phylogeny Group, and authors associated with the Smithsonian Institution Libraries. Molecular phylogenies published by teams at Max Planck Society, Cold Spring Harbor Laboratory, ETH Zurich, University of Geneva, and CNRS have clarified relationships among genera such as those described by Carl Linnaeus and later revised in works by Augustin Pyramus de Candolle, George Bentham, and Joseph Dalton Hooker. Cladistic analyses feature methods developed at Harvard Forest, Montreal Botanical Garden, and Royal Botanic Gardens, Kew, and are cited alongside evolutionary models used at Princeton University, Stanford University, and Yale University.

Species occur across continents and islands, recorded in floras compiled by Botanical Society of Britain and Ireland, New Zealand Plant Conservation Network, Instituto de Biologia UNAM, and national herbaria including Herbarium Berolinense, Naturalis Biodiversity Center, and Museo Nacional de Ciencias Naturales. Habitats range from Mediterranean regions documented in field guides by Royal Botanic Garden Edinburgh and Botanical Society of Scotland to alpine zones surveyed by scientists from Swiss Federal Institute of Technology and Université Grenoble Alpes, and desert locations studied by researchers at the Desert Research Institute and Tel Aviv University.

Ecological interactions involving pollinators, herbivores, and pathogens are examined in collaborations among researchers from French National Centre for Scientific Research, Monash University, University of São Paulo, University of Cape Town, and Peking University. Pollination studies cite work on nectar ecology and floral syndromes by teams at Cornell University, University of Illinois Urbana-Champaign, University of Florida, and the Smithsonian Tropical Research Institute. Biotic associations are reported in conservation assessments by IUCN, regional red lists such as those by NatureServe, and programs run by the European Commission and United Nations Environment Programme.

Horticultural and ethnobotanical uses are documented in manuals published by the Royal Horticultural Society, Botanic Gardens Conservation International, American Horticultural Society, and commercial nurseries like Monrovia Nursery Company. Crassulaceae species appear in collections at institutions including Jardín Botánico de Bogotá, Holderness School Greenhouse, and university arboreta at Cornell University, University of California Botanical Garden at Berkeley, and University of Michigan Botanical Gardens. Cultivation protocols reference propagation techniques from the National Gardening Association and pest management guides from the United States Department of Agriculture and Agriculture and Agri-Food Canada.

Conservation status and threat assessments feature in reports by IUCN Red List, Convention on Biological Diversity, Botanic Gardens Conservation International, and national agencies like US Fish and Wildlife Service, South African National Biodiversity Institute, and Australian Government Department of Agriculture, Water and the Environment. Habitat loss and climate change impacts on populations are modelled in studies from Intergovernmental Panel on Climate Change, United Nations Framework Convention on Climate Change, and research groups at Imperial College London and University of Exeter. Ex situ conservation efforts are coordinated through networks including the Millennium Seed Bank Partnership and seed banks at Royal Botanic Gardens, Kew and Millbrook Research Farm.
