(Compositae, Anthemideae) is represented in Corsica (Corse) by two species: the tetraploid L. ircutianum DC. and the hexaploid L. corsicum (Less.) DC. The indication of the occurrence of the diploid L. vulgare Lam. on the island and of a tetraploid chromosome number for L. corsicum, given in former treatments of the genus for Corsica, could not be corroborated. AFLP fingerprinting further suggests that the infraspecific taxonomy of L. corsicum with two subspecies (L. corsicum subsp. corsicum and subsp. fenzlii) and three forms (L. corsicum f. corsicum, f. pinnatifidum and f. eschenlohrianum), which is mainly based on differences in the degree of leaf dissection, is not backed by genetic discontinuities. Owing to the observed little variation in leaf dissection within populations in the wild and the constancy of these features under cultivation, we propose the rank of varieties to taxonomically acknowledge these different stages in the broad spectrum of leaf-dissection grades exhibited by L. corsicum. As a consequence, the two new combinations L. corsicum var. eschenlohrianum (Gamisans) Vogt, Hugot & Oberpr. and L. corsicum var. fenzlii (Gamisans) Vogt, Hugot & Oberpr. are proposed."

Neotropical species of the Adiantum raddianum group (Pteridaceae) / Regina Y. Hirai in Willdenowia, vol. 49, n°3 (Année 2019)

Public [article]  inWilldenowia > vol. 49, n°3 (Année 2019) . - pp. 295-317 Titre : Neotropical species of the Adiantum raddianum group (Pteridaceae) Type de document : texte imprimé Auteurs : Regina Y. Hirai, Auteur ; Jefferson Prado, Auteur Année de publication : 2019 Article en page(s) : pp. 295-317 Langues : Allemand (ger) Catégories : [Espèces (in biblio)] Adiantum [Thèmes] Taxonomie Mots-clés : fougère  lectotype  morphologie  nomenclature  ptéridophite  typification Résumé : "As recently demonstrated, the group of Adiantum raddianum is monophyletic and can be recognized by round-reniform indusia and veins ending in sinuses at the sterile segment margins. The most related species belong to the A. poiretii group, which is morphologically distinct by the oblong to lunate indusia. In the A. raddianum group sixteen species are recognized in the present work. Among these species, A. patens s.l. is the unique species that occurs in Africa outside the neotropical region. Adiantum raddianum is the broadest distributed species of the group, widely cultivated globally, and it has become naturalized in the Paleotropics and other regions. Typifications are presented for two accepted names: A. lorentzii and A. ruizianum. Several other typifications are also presented for synonymized species. Adiantum alan-smithii, A. galeottianum, A. imbricatum, A. lobatum, A. ruizianum, A. shepherdii and A. subvolubile are species with restricted distributions occurring only in one or two countries. An identification key, as well as descriptions, synonymies, discussion on morphology and taxonomy, illustrations and a list of specimens examined are provided."
