It occurs widely on the eastern fringe of the Mediterranean area in Turkey, Syria, Lebanon and Israel. First collected by Leonhard Rauwolf as early as 1575, it was made known by him through the publication of a description and an illustration. His herbarium specimen, among the first collected in the Near East, survives in Leiden. More than two centuries had to pass until André Michaux and, independently, Jean Jacques Houtou de Labillardière collected M. campanuloides again and made specimens and seeds available to the botanical community in Paris. On the basis of living material, but including references to herbarium specimens, Charles-Louis L'Héritier de Brutelle was the first to provide a binomial for this striking plant. This paper focuses on the widely unappreciated record of herbarium specimens and printed illustrations, and lists and comments on early specimens collected in the wild as well as those cultivated in botanical gardens up to 1800. In addition, the name M. campanuloides is properly lectotypified."

The Malagasy enigmatic genus Apodocephala (Asteraceae), a new member of the tribe Athroismeae / Annika Bengtson in Willdenowia, vol. 51, n°2 (Année 2021)

Anderberg, Auteur ; Sylvain G. Razafimandimbison, Auteur Année de publication : 2021 Article en page(s) : pp. 221-230 Langues : Anglais (eng) Catégories : [ZG] Madagascar [Espèces (in biblio)] Asteraceae Mots-clés : Apodocephala Résumé : "Apodocephala is a small genus of nine species of shrubs and trees endemic to Madagascar and currently classified in the tribe Astereae (Asteraceae). However, its present tribal position has been questioned, as it lacks some of the salient morphological features of that tribe. This study includes for the first time DNA sequences from Apodocephala (two species including the type of the generic name) to test its phylogenetic position. Phylogenetic analyses based on sequence data from nuclear ribosomal (ETS and ITS) and plastid (ndhF and trnL–trnF) DNA regions, using Bayesian inference and maximum parsimony methods, strongly reject the placement of Apodocephala in the Astereae. Our results, instead, support its position as sister to the Malagasy monospecific genus Lowryanthus within the tribe Athroismeae. Morphological comparison of these sister genera reveal similarities in cypsela morphology, and the inclusion of Apodocephala in the subtribe Lowryanthinae is proposed here. The tribe Athroismeae is now represented by ten genera (Anisochaeta, Anisopappus, Apodocephala, Artemisiopsis, Athroisma, Blepharispermum, Centipeda, Leucoblepharis, Lowryanthus and Symphyllocarpus), six of which occur in Madagascar. The Malagasy Athroismeae occur in all Malagasy terrestrial ecosystems (rainforests, deciduous dry forests, thicket spiny forests and savannas) and are likely the result of multiple independent colonization events mostly from mainland Africa."

A conspectus of Tephroseris (Asteraceae: Senecioneae) in Europe outside Russia and notes on the decline of the genus / Joachim W. Kadereit in Willdenowia, vol. 51, n°2 (Année 2021)

Public [article]  inWilldenowia > vol. 51, n°2 (Année 2021) . - pp. 271-317 Titre : A conspectus of Tephroseris (Asteraceae: Senecioneae) in Europe outside Russia and notes on the decline of the genus Type de document : texte imprimé Auteurs : Joachim W. Kadereit, Auteur ; Paula Laux, Auteur ; Markus S. Dillenberger, Auteur Année de publication : 2021 Article en page(s) : pp. 271-317 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Asteraceae [Espèces (in biblio)] Tephroseris [ZG] Europe Mots-clés : Senecioneae Résumé : "Tephroseris is generally considered a difficult genus. Based on the examination of extensive herbarium material and considering the existing literature, we recognize seven species in Europe outside Russia. These are T. palustris, T. integrifolia with subsp. integrifolia, subsp. aurantiaca, subsp. capitata, subsp. maritima, subsp. serpentini and subsp. “tundricola”, T. balbisiana, T. crispa, T. helenitis, T. longifolia and T. papposa. Phylogenetic analysis of ITS and ETS sequences showed that these species fall into three lineages. These are: (1) T. palustris, clearly related to Arctic species of the genus; (2) T. integrifolia; and (3) the remaining species. Molecular dating of the T. integrifolia lineage resulted in a crown group age of 1.76 (0.85–2.87) million years. Possible reasons for taxonomic difficulties in the genus in Europe outside Russia may include its young phylogenetic age and extensive migration and genetic admixture in the Quaternary. The decline of the genus in Europe outside Russia is documented and discussed. We consider it possible that its decline is related to rising global temperatures."
