Notes taxonòmiques, nomenclaturals i corològiques de les espècies de Verbascum L. (Scrophulaeiaceae) a Mallorca

Hom ha reunit en el present treball un seguit de comentaris taxonòmics, nomenclaturals i corològics de les espècies de Verbascum L. (includ. Celsia L.) presents a l'illa de Mallorca. Per a l'elaboració d'aquest estudi hom ha consultat els següents herbaris: BC, BCC, BCF, COI, MA, MAF, MPU, així com els del Col•legi d'Apotecaris de Palma (Herb. Apot.), Coilegi de la Salle de Pont d'Inca (Herb. Bianor) i de Palma (Herb. Bianor- P), i els herbaris particulars de J. Orell (Herb. Orell) i de F. Bonafe (Herb. Bonafe).This work presents taxonomical, nomenclatural, and chorological studies on the taxon Verbascum L. (includ. Celsia L.) of Majorca island. The species V. nigrum Vill. and V. Virgatum Stockes must be eliminated from the Balearic Flora. V. boerhavii L. var. bicolor (Bad.) Arcang. and V. blattaria L. are recorded for the first time in the Balearic Islands; likewise, V. boerhavii var. knochei is described. V. portae Willk. is regarded as coespecific with V. boerhavii L. var. boerhavii

Carpologia del genero Anthemis L. en la Peninsula Iberica e Islas Baleares

Se presenta el estudio carpológico de las especies Ibéricas y Baleáricas del género Anthémis L. A partir de la valoración crítica de los caracteres empleados y de la descripción morfológica, al microscopio óptico y electrónico de barrido, de las cipselas de los táxones que integran el grupo, se ha confeccionado una clave que permite la identificación de las especies

Phylogenetic studies in Gnaphalieae (Compositae): The genera Phagnalon Cass. and Aliella Qaiser & Lack

130 p., tablas, mapas, fot. -- Se corresponde con el capítulo 7 del libro Recent Advances in Pharmaceutical Sciences IIIThe precise generic delimitation of Aliella and Phagnalon, and their closest relatives within the Gnaphalieae are discussed in this review. Among the main results obtained, we have found that the genera Aliella and Phagnalon are nested within the “Relhania clade” and Anisothrix, Athrixia and Pentatrichia are their closest relatives. Macowania is also part of the “Relhania clade”, whereas the subtribal affinities of Philyrophyllum lie within the “crown radiation clade”. The monophyly of Aliella and Phagnalon is not supported statistically. In addition, Aliella appears to be paraphylethic in most of the analyses performed. The resulting phylogeny suggests an African origin for the ancestor of Aliella and Phagnalon and identifies three main clades within Phagnalon that constitute the following natural groups on a geographic basis: (1) the Irano-Turanian clade; (2) the Mediterranean-Macaronesian clade; and (3) the Yemen-Ethiopian clade. Some endemics to Yemen and Ethiopia appeared merged in the Mediterranean-Macaronesian clade, providing new evidence of the phytogeographical links between Macaronesia, Eastern Africa and Southern Arabia. Incongruities between the chloroplast and nuclear molecular data and the lack of resolution in some clades may indicate that hybridization could have played an important role in the evolution and diversification of both Phagnalon and Aliella.This work has been partly financed by the Spanish government (REN2002-04634-C05-01, CGL2004-04563-C02-01/BOS) and the Catalan government (“Ajuts a grups de recerca consolidats” 2009/SGR/00439).Peer reviewe

Imprinting skyrmions in thin films by ferromagnetic and superconducting templates

Magnetic skyrmions are promising candidates as information carriers in a new generation of memories. Here, we study the physical conditions for nucleating and stabilizing skyrmions by using local magnetic fields. We theoretically demonstrate how skyrmions can be imprinted in ultrathin ferromagnetic films, either individually and also in large numbers by bringing a magnetic nanostructured template close to the film. In this latter case, two kinds of templates, allowed by present-day nanotechnologies, are proposed: arrays of ferromagnetic nanorods or superconducting vortices
