[Thèmes] Reproduction sexuée
[Thèmes] TaxonomieMots-clés : nouvelle espèce Balkan diploïdie Résumé : "The Euro-Siberian complex ofRanunculus auricomus(Ranunculaceae) consists of about 800 mainly apomictic and polyploid taxa. So far, only four sexual species have been described (R. carpaticolaSoó,R. cassubicifoliusW. Koch,R. notabilisHörandl & Gutermann and R. marsicusGuss. & Ten.). With the exception ofR. marsicusand rare autotetraploids ofR. cassubicifolius, sexuality seems to be linked to diploidy. Using flow cytometric ploidy estimation, flow cytometric seed screen and pollen quality, six new diploid sexual species have been revealed in C France, C and SE Slovenia and Croatia:Ranunculus austroslovenicusDunkel,R. calapiusDunkel,R. cebennensisDunkel,R. mediocompositusDunkel,R. peracrisDunkel andR. subcarniolicusDunkel. Here, they are described and depicted in detail. Sexual reproduction has been verified forR. austroslovenicus, R. cebennensis, R. subcarniolicusand also for the previously describedR. envalirensisGrau andR. flabellifoliusHeuff. ex Rchb."

Titre : Northern Hemisphere disjunctions in Lactuca (Cichorieae, Asteraceae) : independent Eurasia to North America migrations and allopolyploidization Type de document : texte imprimé Auteurs : Kathy E. Jones, Auteur ; Edward E. Schilling, Auteur ; Elisabete F. Dias, Auteur ; Norbert Kilian, Auteur Année de publication : 2018 Article en page(s) : pp. 259-284 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Lactuca
[Thèmes] BiogéographieMots-clés : Cichorieae allopolyploïdie analyse des temps de divergence hémisphère nord phylogénétique disjonction des plantes Résumé : "The Lactucalineage is one of nine lineages in the lettuce subtribe (Cichorieae, Asteraceae) distributed in Europe, Africa, Asia and North America. Within the Lactucalineage two clades show disjunct Eurasian-North American distributions. One disjunct clade consists of diploids (x= 8) and allotetraploids (x= 17), the former restricted to Eurasia and the latter to North America and the Azores. In contrast, members of the other Eurasian-North American disjunct clade are all diploid (x= 9), like the remainder of the Lactucalineage (diploid,x= 8 or 9). The aims of the present study were to investigate the migration pathways that led to the disjunct distributions of these two Eurasian-North American clades and the potential progenitors of the allopolyploid taxa. We conducted deep taxon sampling and multi-locus phylogenetic analyses using nuclear ribosomal DNA (ETS and ITS), a low-copy nuclear marker (A44) and five non-coding plastid markers. Divergence time estimations with BEAST and ancestral biogeographic estimations with BioGeoBEARS suggested that both lineages reached North America by the late Miocene. Cloning of the A44 region revealed two sequence copies within allopolyploid individuals that were resolved in divergent clades and this helped to identify potential progenitors. We provide competing hypotheses for the progenitor species and biogeographic pathways that gave rise to the allotetraploid lineage, and we propose a North American origin for the Azorean endemic. Taxonomic conclusions includeL. raminifoliavar.mexicanabeing raised to specific rank with the nameL. brachyrrhynchaand the alleged endemicL. jamaicensisin fact represents the SE AsianL. indica, introduced to Jamaica."

[Thèmes] Histoire de la botanique
[Thèmes] TaxonomieMots-clés : 20ème siècle Résumé : "We discuss the development of, and trends in, vascular plant taxonomy in Portugal during the 20th century, with emphasis on the institutions and taxonomists that were instrumental in advancing and facilitating this branch of scientific botanical endeavour. We show that the bulk of the nomenclatural novelties published by Portuguese botanists for elements of the vascular flora of the country, and beyond, were produced by a small group of 69 taxonomists who were mostly based at institutions in one of three Portuguese cities: Coimbra, Lisboa (Lisbon) and Porto. In all three instances the individuals were associated with local herbaria that were managed by universities, while in Lisboa other government-sponsored projects and institutions additionally played a pivotal role in the production of complete or partial Floras for Portugal and its former colonies. These individuals are comprehensively tabulated and biographical information is provided for all of them. With 440 names published, Rosette Mercedes Saraiva Batarda Fernandes (1916 – 2005), who worked at the University of Coimbra, was the most prolific taxonomist in terms of publishing new names. She was the sole author of more than half of these names. Biographies are provided for the ten most prolific Portuguese authors of vascular plant names."
