Historical evidence for a pre-Columbian presence of Datura in the Old World and implications for a first millennium transfer from the New World

Datura (Solanaceae) is a small genus of plants that, for long, was thought to occur naturally in both the New and Old Worlds. However, recent studies indicate that all species in the genus originated in the Americas. This finding has prompted the conclusion that no species of Datura could have been present in the Old World prior to its introduction there by Europeans in the early 16th century CE. Further, the textual evidence traditionally cited in support of a pre-Columbian Old World presence…

The first checklist of alien vascular plants of Kyrgyzstan, with new records and critical evaluation of earlier data. Contribution 1
Point maps of species distributions in Kyrgyzstan are provided on the basis of a complete inventory of the literature data, herbarium specimens and documented observations, and the recent fieldwork.
Molecular Phylogeny of the Jimsonweed Genus Datura (Solanaceae)
Phylogenetic analyses confirmed the monophyly of the Daturae clade with two genera, Datura with herbaceous species and Brugmansia with woody species.
In the wild hybridization of annual Datura species as unveiled by morphological and molecular comparisons
The findings suggest that the natural hybridization of annual Datura species occurs and could be the first step for speciation.
A molecular phylogeny of the Solanaceae
The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive "x = 12" clade, which includes Nicotiana and the Australian tribe Anthocercideae, and provide greater resolution among lineages within Solanoidesae.
Lockdown botany 2020: some noteworthy records of alien plants in Kyiv City and Kyiv Region
Noteworthy records of 11 alien plant species in Kyiv City and Kyiv Region made mainly in 2020 are discussed. In particular, new localities of the following taxa are reported: Amaranthus spinosus,
Kodamaea transpacifica f.a., sp. nov., a yeast species isolated from ephemeral flowers and insects in the Galapagos Islands and Malaysia: further evidence for ancient human transpacific contacts.
Sequences of the D1/D2 domains of the large subunit rRNA gene indicated that these strains belong to a novel yeast species of the Kodamaea clade, although the formation of ascospores was not observed, and the human-mediated dispersion of this species by transpacific contacts in ancient times is suggested.
The history of the Portulaca oleracea aggregate in the Emilia-Romagna Po Plain (Italy) from the Roman Age to the present
Portulaca oleracea L. is a cosmopolitan synanthropic species, of uncertain origin, known in Italy since the Roman Age. The aim of this work is to reconstruct the history of P. oleracea aggregate in

Modern sophisticated archeometric instruments are increasingly capable of detecting the presence of psychoactive plant sources in archeological contexts, testifying the antiquity of humanity’s search


Proceedings of the SMBE Tri-National Young Investigators' Workshop 2005. Reconstructing the origins and dispersal of the Polynesian bottle gourd (Lagenaria siceraria).
A dual origin for the Polynesian bottle gourd is supported: the chloroplast markers are exclusively of Asian origin, but the nuclear markers show alleles originating in both the Americas and Asia.
AFLP assessment of diversity in sweetpotato from Latin America and the Pacific region: Its implications on the dispersal of the crop
The results suggest that Peru-Ecuador may not be the source of the Oceania sweetpotato germplasm, and natural dispersal from Mesoamerica is an alternative explanation, to the ‘Kumara hypothesis’, for the origin of theOceaniasweetpotato.
Oceanic drift of gourds-experimental observations.
There exists the possibility that fruits of Lagenaria may have been transported to the New World by oceanic currents, and this possibility has been suggested by Towle (1952), and she cites certain pieces of evidence from the literature to support this idea.

Wind and ocean transport of organisms and propagules throughout the Tertiary, and especially at peaks of warmth, was likely a more important means of dispersal than would seem plausible under present conditions.
AFLP analysis of genetic relationships in the tribe Datureae (Solanaceae)
The AFLP technique was evaluated as a tool for assessing species relationships within the tribe Datureae and genetic distances were estimated and a new classification is proposed, which maintains the arborescent species as a separate genus, Brugmansia, and recognises three sections within the genus Datura.
Ecological, Taxonomic, and Life History Correlates of Seed Mass Among Indiana Dune Angiosperms
This study evaluated the ecological and taxonomic correlates of seed mass variation among 648 angiosperm species of the Indiana Dunes region to discover the strong effect of life history on seed mass, due primarily to the extremely large seeds produced by trees.
The United States naturalized flora: Largely the product of deliberate introductions'
The likelihood that the majority of species now naturalized in the United States has a history of deliberate introduction and post-immigration cultivation provides a plausible explanation for their persistence in a new range.
Phenetic analysis of Datura section Dutra (Solanaceae) in Mexico
Phenetic analysis of morphological characters of taxa in the section Dutra of the genus Dutra supported the recognition of seven species which shared similar anther length, seed surface texture, fruit dehiscence, corolla length, calyx lobe length, stamen length and leaf length, and it is probable that the domesticated D. metel was derived from wild D. inoxia.
