Flor de Toloache is a common Spanish name applied to several night-blooming species in the genus Datura and related taxa within the family Solanaceae, particularly associated with traditional landscapes of Mexico and parts of Central America. The term appears across literature on ethnobotany, folklore, and traditional medicine where it intersects with practices documented by investigators from institutions such as the Smithsonian Institution, Universidad Nacional Autónoma de México, and the Royal Botanic Gardens, Kew. Scholarly treatments connect the plant to historical sources including accounts from the era of Hernán Cortés, botanical descriptions by Carl Linnaeus, and later taxonomic work by George Bentham and Augustin Pyramus de Candolle.
The vernacular name derives from Spanish-speaking regions influenced by colonial and indigenous naming recorded in chronicles such as those by Bernal Díaz del Castillo and linguistic studies at El Colegio de México. The epithet "toloache" appears in dictionaries compiled by philologists like Ignacio Manuel Altamirano and ethnolinguists associated with Instituto Nacional de Antropología e Historia. Comparable names occur in Nahuatl glosses preserved in the Florentine Codex compiled under Bernardino de Sahagún and in vocabularies collected by Alexander von Humboldt. Colonial herbals held in the Real Jardín Botánico (Madrid) and treatises by Francisco Hernández de Toledo show early European reception of the plant's name and uses.
Taxonomic descriptions follow conventions set by Carl Linnaeus and subsequent revisions by botanists at Kew Gardens and the United States Department of Agriculture. Plants called by this name are typically short-lived perennials or annuals in Solanaceae with features described in floras such as the Flora of North America and regional treatments produced by CONABIO and researchers at Universidad Autónoma Metropolitana. Diagnostic characters cited in monographs by authorities like Hermann Karsten include large trumpet-shaped nocturnal flowers, spiny dehiscent fruits, and alkaloid-rich tissues noted in chemical surveys by researchers at Harvard University, University of Oxford, and Universidad Nacional Autónoma de México. Herbarium specimens are housed at institutions such as the New York Botanical Garden, Kew Herbarium, and the Field Museum of Natural History.
Occurrences are documented in biogeographic studies published by INEGI, CONABIO, and the International Union for Conservation of Nature assessments that map populations across Mexico, Guatemala, Belize, and parts of Honduras and El Salvador. Habitat descriptions appear in ecological surveys by UNAM, Universidad de Guadalajara, and conservation reports from World Wildlife Fund field programs. The plant colonizes disturbed sites noted in landscape ecology work at Carnegie Institution for Science and floristic inventories in protected areas such as Sierra de Manantlán Biosphere Reserve and El Triunfo Biosphere Reserve.
Ethnobotanical documentation by researchers affiliated with Smithsonian Institution ethnobotany programs, University of California, Berkeley, and El Colegio de Michoacán records ritual uses among communities studied by anthropologists linked to UNAM and University of Oxford. Accounts connect the plant to ceremonial practices reported in fieldwork by Miguel León-Portilla and ritual specialists cited in studies by María del Carmen Martínez. The plant appears in folk narratives collected in archives of Biblioteca Nacional de México and cultural analyses presented at conferences hosted by Instituto Nacional de Bellas Artes and American Anthropological Association.
Medicinal uses are reported in compilations by World Health Organization monographs and regional pharmacopoeias surveyed by researchers at Instituto Politécnico Nacional and Universidad Autónoma de Baja California. Cautionary notes on toxicity draw on clinical case reports published in journals affiliated with Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mayo Clinic, and Johns Hopkins University. While some traditional culinary lore in regions documented by UNAM and ethnographers at University of Texas at Austin mentions ceremonial infusions, modern herbal pharmacopeias from Kew and safety assessments by FDA-style agencies recommend against ingestion due to tropane alkaloids analyzed by chemists at Massachusetts Institute of Technology and University of Cambridge.
Conservation status assessments appear in checklists compiled by IUCN specialists and botanical garden ex situ programs at Royal Botanic Gardens, Kew, Missouri Botanical Garden, and Jardín Botánico de la Universidad Nacional Autónoma de México. Cultivation protocols are included in manuals from FAO agroecology initiatives and horticultural guides produced by Royal Horticultural Society and university extension services such as those at University of California Cooperative Extension and Texas A&M AgriLife Extension Service. Restoration projects in regions like Chiapas and Oaxaca involve collaboration with NGOs including Conservation International and community groups documented by FAO case studies.
The plant figures in artistic and literary works archived at Museo Nacional de Antropología (Mexico) and in contemporary media discussed at festivals like Festival Cervantino and exhibitions at Museum of Modern Art (New York). It appears in popular culture references cataloged by scholars at University of Southern California and in musicology studies by researchers at Berklee College of Music where motifs from Mexican folklore intersect with representations in cinema studied by University of California, Los Angeles film scholars. Public interest has prompted coverage by outlets such as National Geographic, Smithsonian Magazine, and BBC News producing materials used by educators at institutions like Monterrey Institute of Technology and University of Edinburgh.
