![]() ![]() ![]() ![]() The Datura clade consists of two distinct lineages D. The monophyly of the Datura clade was confirmed with two genera, Datura containing herbaceous species and Brugmansia with woody species. Phylogenetic analyses by Bye and Sosa (2013) divided species of Datura into three sections, Ceratocaulis, Datura, and Dutra, based upon the position and type of the fruit. ![]() These are all long-lived, tuberous rooted perennials, in contrast to other species that are tap-rooted annuals. innoxia is the most probable progenitor of D. The combination of genetic and cladistic data indicates that D. lanosa being the basal taxon of this group. wrightii, and of the cultivated species, D. Full descriptions are given by Haegi (1976) of the wild species D. is sometimes reported as a synonym for D. Attention is required with synonymy, as D. Two subspecies are described by Missouri Botanic Garden (2014), subsp. inoxia, but this difference in spelling should be taken into consideration when searching the literature. innoxia is the spelling used in this datasheet, with more than 600 records in CAB Direct whereas there are less than 100 for D. However, the species name with only a single ‘n’ as D. is the accepted name in The Plant List (2013) and the Royal Botanic Garden Edinburgh (2014), and is the most commonly used. innoxia has been listed as a Declared Weed in South Africa which is prohibited and must be controlled ( AGIS, 2007).ĭatura innoxia Mill. However, timely cultivation or use of herbicides can easily control the species. innoxia also readily escapes from gardens where it is being cultivated. Seed inspection and certification agencies should be especially vigilant when batches of seed for planting are imported from areas where Datura species are known to occur. Several species of Datura have been spread around the world as contaminants of agricultural seed. It is toxic to animals and humans, with all plant parts and seeds containing toxic alkaloids. stramonium, that achieve high densities and are difficult to control. It is one of several invasive Datura species including D. It is widely naturalized in the tropics and increasingly in temperate Europe and North America. innoxia is invasive in the Galapagos islands, New Caledonia, mainland China and Taiwan, and in Ethiopia, Kenya, Namibia and South Africa. ![]()
