In this study, we evaluate the application of geometric morphometric methods to flowers of herbarium specimens, a material that is still being massively overlooked as far as these methods are concerned. Flowers of Delphinieae (Ranunculaceae) are synorganized: the spurred and nectariferous dorsal petals are nested within the spur or hood of the dorsal sepal. The study of synorganized structures is challenging, and geometric morphometric-oriented investigation may provide working hypotheses for an evo-devo exploration of such hyperorgan formation. We analyze here the floral shape of Delphinieae using geometric morphometric methods and demonstrate the effectiveness of these methods on dry and compressed flowers. We also show the diagnostic value of the dorsal half of the perianth of the Delphinieae flower, and suggest some trends to help design future studies on the evolutionary development of spur formation and the co-evolution of Delphinieae flowers with their pollinators."

Titre : The taxonomic circumscription of Aconitum subgenus Aconitum (Ranunculaceae) in Europe Type de document : texte imprimé Auteurs : Józef Mitka, Auteur ; Andriy Novikov, Auteur ; Walter Karl Rottensteiner, Auteur Année de publication : 2021 Article en page(s) : pp. 11-45 Langues : Multilingue (mul) Catégories : [Espèces (in biblio)] Aconitum
[Thèmes] PhytogéographieMots-clés : révision taxonomique hybride nomenclature, clé de détermination Résumé : "In this article, we present a revised taxonomic circumscription of Aconitum subg. Aconitum (Ranunculaceae) in Europe. In total, the subgenus contains some 250 species with the major center of diversity in Eastern Asia. Altogether 94 taxa (species and infraspecific taxa, including hybrids) occur in Europe. Among them, 22 are native species, and 28 are nothospecies (including hybrid formulae). The research is based on former (since Linnaeus) and recent species diagnoses integrating herbarium and field studies carried out in the Alps, Carpathians, Balkans, Spanish Sierra Nevada, Sudetes, and Corsica. The subgenus includes three sections in Europe: the diploid sect. Cammarum, the tetraploid sect. Aconitum, and the monospecific, allopolyploid sect. Angustifolium. Additionally, a triploid, hybridogenous nothosection Acomarum (sect. Aconitum × sect. Cammarum) is presented. For each species, type citation, a concise morphological description, including infraspecific variation and hybridization, geographical distribution, and iconography sources are given. Also, a key to the determination of all taxa is presented. The proposed system scrutinizes former and recent species concepts and gives a base for further studies on the genus’ phylogeny and biotechnology."
