The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability these threatened by recent discussions asking for a fairer nomenclature, raising possibility bulk revision processes "inappropriate" names. It evident such proposals come from very deep feelings, but we show how can irreparably damage foundation biological communication and, turn, sciences depend on it. There are four essential consequences...
Asteraceae is the world’s richest plant family and found on all continents, in environments ranging from coast to highest mountains. The shows growth forms and, as other angiosperm families, species richness concentrated tropical regions. South America has diversity of world, yet taxonomic distributional knowledge gaps remain. This study compiles an updated catalog native America, based national regional checklists ongoing large-scale flora projects. resulting checklist includes a total...
Las especies del género Strelitzia (Strelitziaceae) son originarias sudeste de África y se caracterizan por sus enormes inflorescencias cuyas flores espata recuerdan la cabeza un ave. nicolaii Regel Körn., especie mayor altura género, forma parte colección viva Jardín Botánico Arboretum en el predio principal Museo Argentino Ciencias Naturales "Bernardino Rivadavia" (MACN), donde alcanza más 6 m. Sobre base documentación bibliográfica e identificación especie, pudo corroborar que planta fue...
Abstract Praxelis clematidea is a relatively unknown herb native to South America that has spread globally over the past four decades. In this study, we integrate ecological niche modelling (ENM) and shift analyses understand its distribution, test conservatism hypotheses, identify potential invasion sites under different climate change scenarios. range, P. prefers climates with mild annual temperatures winters. This species shows great continue spreading. Probable include northern America,...
A taxonomical study of the Chilean Stevia is herein presented since there no agreement on current names and number species for Chile. detailed morphological analysis type non-type specimens including new field observations was undertaken. In this work we recognized only one in Chile: S. philippiana. This has a wide variation mainly leaf pappus features. lectotype name hyssopifolia designated. var. panulensis regarded as synonym On other hand, adenophora chamaedrys were excluded from flora....
The South American central Andes have a great richness of Asteraceae, where the genus Stevia (Eupatorieae, Piqueriinae) is also especially diverse. taxonomy species in southern part pose challenge because unclear delimitation among and overlap morphological characters. Two complexes were identified for region comprising north Argentina Bolivia. In this study, our objectives to employ morphometric analyses assess taxa within alpina Griseb. chamaedrys complexes. We aimed identify informative...
Abstract Xanthium is a genus of annual herbaceous plants that stands out within Asteraceae for being wind‐pollinated, diclinous monoecious, and bearing solitary pistillate flowers in peculiar spiny structures (burs). sect. Acanthoxanthium native to South America characterized by the presence trifurcate spines at base leaves. Past taxonomic treatments section have been contradictory, some recognising up six species, others reducing all single polymorphic species. Altogether, 42 samples X....
The Neotropical genus Acanthostyles R.M.King & H.Rob. (Asteraceae, Eupatorieae) occurs from northern Argentina up to Patagonia, southern Brazil, central and Bolivia, Uruguay. Different taxonomic treatments have suggested that might include two species (A. buniifolius (Hook. Arn.) A. saucechicoensis (Hieron.) H.Rob.), or even only a single, highly variable, species. Therefore, detailed morphological study revision of were carried out. A principal component analysis 73 specimens,...
Currently, in Argentina 368 species of true ferns (i.e. Polypodiopsida class) are distributed throughout the country, however, only four them have been mentioned until now as weeds and ruderal species. The goal this work was to generate an update weedy from Argentina, including morphology, distribution, type weed according their impact on natural habitats and/or human activities. All Argentinian fern were analyzed based references, herbarium specimens, field trips. As a result our study 25...
Abstract A revision and a morphological analysis of the Uruguayan species Stevia (Compositae, Eupatorieae) were performed. Leaf, inflorescence, pubescence pappus traits identified as key to separate species. entreriensis, S. entreriensis var. minor, Dissothrix hassleriana considered synonyms hirsuta, ophryodonta oxylaena veronicae. Lectotypes for names cinerascens, megapotamica, linariifolia, selloi, selloi yparacayensis, veronicae designated. burkartii was excluded from flora. As result, 10...
During the course of revision (in progress) South American species Tagetes, we detected need for nomenclatural clarifications and typifications in order to correct application taxa´s names. We analyzed protologues, biographies authors collectors, original common materials, morphological traits. As a result clarified author citations T. anisata pseudomicrantha, type localities several taxa. In addition, designated 12 lectotypes two epitypes following plant names: anisata, bonariensis,...
The high biodiversity and species richness, along with a great variety of ecosystems, turn northwestern Argentina into an adequate area for study the possible effects climate change on distribution organisms. Asteraceae is well-represented family flowering plants in this area; especially, genus Stevia, 25 which inhabit different environments. goals were: 1) to model habitat suitability five Stevia distributed Argentina, 2) project such under greenhouse gas emission scenario by 2050. Species...

Eleven species of Stevia were reported from Uruguay: S. aristata, burkartii, cinerascens, congesta, entreriensis, gratioloides, multiaristata, ophryodonta, sabulonis, satureiifolia, and selloi. Seven are shared with Argentina, five Brazil, four Paraguay, two endemic to Uruguay. During the revision these Stevia, we detected names which need lectotypifications. As a result our analysis lectotypes designated for currently accepted in Stevia: polycephala (= aristata) Dissothrix hassleriana...
The monotypic genus Jodina is endemic to central and southeastern South America, common in forests scrubland environments. fruit type controversial since it has been described at different stages of development. main objective this work was analyze the morphology J. rhombifolia during its maturation attain a consensus about type. Also characteristics seed development anatomy were analyzed detail. Material processed according conventional techniques for LM SEM studies. pseudodrupe ovary...
Introducción y objetivos: Actualmente numerosas especies, nativas exóticas, llamadas “cardos” están ampliamente distribuidas en Argentina. Durante el siglo XVIII varias publicaciones jesuíticas mencionaron este país, como trabajo ilustrado de Florián Paucke. El objetivo principal del es recopilar, las fuentes escritas XVIII, los registros plantas denominadas o nombres similares; segundo lugar, identificar a nivel especie entidades mencionadas por Paucke “azafrán”, “cardo” “cardo hortense”;...
Carduus tenuiflorus Curtis is described as a new alien plant species for Chile, whose introduction into the country proposed around year 1928. An identification key of genus L. present in Chile added.
