The genus Logfia Cass. was described by Cassini in 1819 and has always been considered closely related to Filago L. The species of Logfia have been frequently included within Filago but, recently, based on morphological characters and DNA sequence analysis it has been demostrated that Logfia is more closely related to the American representatives o...

We present two Iberian-African plants which are new records for the flora of the Region of Murcia and are mainly located in the southwestern part of the province. Several aspects related to corology, rarity, degree of threat and conservation of these species are discussed. The presence of Kalanchoe × houghtonii D.B. Ward, an invasive alien plant which is seriously affecting the threatened flora present at the Castle of Águilas, is confirmed.
... The genus was recircumscribed by Galbany-Casals et al. (2010) and Andrés-Sánchez et al. (2011, 2013a, 2015a to include the traditional genera Cymbolaena Smoljaninova (1955: 452), Evacidium Pomel (1875: 287) and Evax Gaertner (1791: 165). However, it is considered separate from Logfia Cassini (1819: 143) (Galbany-Casals et al. 2010;Andrés-Sánchez et al. 2013b) and Bombycilaena (Candolle 1836: 460) Smoljaninova (1955: 448) (Galbany-Casals et al. 2010;Andrés-Sánchez et al. 2014).

This paper is focused on the typification of 36 names provided for Filago species in order to fix their correct usage. Eight of them are accepted names, basionyms or replaced synonyms of accepted names at the specific rank ―i.e. Filago abyssinica, Filago argentea, Filago carpetana, Filago contracta, Filago eriocephala, Filago lutescens, Filago lusitanica and Filago tyrrhenica―. Many others have been extensively used in the taxonomic literature related with the genus (e.g., Filago apiculata, Filago canescens or Filago spathulata). Thirty four lectotypes, three epitypes and one neotype have been selected according to the International Code of Nomenclature for Algae, Fungi, and Plants. Further specimens and/or materials relevant for typification purposes are indicated, together with protologue citations. Finally, Filago albicans is proposed as a replacement name for the illegitimate combination Filago atlantica.

Filago desertorum, as traditionally circumscribed, is a species that shows high levels of morphological variation. Previous authors have even suggested that this taxon should represent a heterogeneous assembly of true biological species. A taxonomic revision of the species included in the Filago desertorum clade was performed, and amplified fragment length polymorphism (AFLP) markers were used to explore the phylogenetic relationships among the members of the clade. Three species are recognized in the group, one of which is newly described. A full description of F. castroviejoi sp. nov., a complete nomenclatural treatment and a key to the species included in the clade are provided. © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, ●●, ●●–●●.
... This study also demonstrated that the traditional generic circumscription within the ''Filago group'' and the traditional infrageneric classification of Filago itself-both based on morphological characters-do not correlate with the inferred phylogenetic relationships. In consequence, in later proposals, the genus Logfia was considered independent from Filago (Galbany- Casals et al. 2010;Andrés-Sánchez et al. 2011a;2013a), while the genera Cymbolaena, Evacidium and Evax were synonymized under Filago. A new infrageneric treatment for the genus Filago was also proposed, comprising four subgenera (Galbany-Casals et al. 2010;Andrés-Sánchez et al. 2011a). ...
The variation and evolutionary dynamics of the twin hairs covering the achenes of the external female florets in Filago and related genera are studied using scanning electron microscope (SEM) and a Bayesian reconstruction of ancestral character states. A molecular phylogenetic hypothesis based on sequences of ITS and ETS (nuclear ribosomal DNA) and plastid rpl32-trnL intergenic spacer regions was used as a framework to test the phylogenetic, evolutionary and taxonomic significance of this character in the study group. The phylogenetic position of three island-endemic species (F. petro-ianii, F. tyrrhenica and F. wagenitziana) is explored. Three types of twin hairs are described, which alone or combined define five different types of indumentum. The results suggest that glabrous achenes are the ancestral condition for “Filago group s.str.”, while the presence of long-clavate twin hairs on the achene represents the ancestral character state for the genus Filago. Several cases of parallelisms are detected. With regard to taxonomy, twin hairs provide additional support for the recognition of Bombycilaena and Logfia at the generic level and allow the taxonomic re-evaluation of F. lutescens subsp. atlantica and F. crocidion. Finally, the utility of a Bayesian Binary MCMC approach (using the software RASP) for evolutionary reconstruction of morphological characters is demonstrated.

This article presents the third part of data on selected new and noteworthy taxa ensuing from the revision of Herbarium collection of the Institute for Nature Conservation of the Vojvodina province (PZZP). Selected taxa include 11 species, three subspecies, three varieties, one infraspecific taxon with indetermined status [stat. indet.] and one nothospecies placed within seven genera (Filago L., Ludwigia L., Luzula DC., Lycopus L., Lythrum L., Phlomis L. and Silene L.). Two varieties (Luzula campestris subsp. campestris var. elata, Silene flos-cuculi subsp. floscuculi var. latifolia) and one infraspecific taxon with indetermined status (Luzula multiflora subsp. multiflora [stat. indet.] b. uliginosa) are new for a flora of Serbia. Additionally, one species (Ludwigia palustris) and one nothospecies (Lythrum ×scabrum) are confirmed for Serbia.
A LA VENTA en www.JOLUBE.es // Este libro es la primera recopilación moderna que recoge todas las plantas vasculares que viven en la Comunidad Autónoma de Cantabria. ATENCIÓN, NO ES UNA GUÍA FOTOGRÁFICA.
En la introducción se da una amplia reseña histórico-botánica y se explica detalladamente la organización del catálogo. La segunda parte se dedica a la descripción geográfica y climática, haciendo hincapié en la descripción fitogeográfica de Cantabria. La parte principal del libro corresponde al catálogo florístico, que consta de 2321 táxones (incluye subespecies e híbridos; 2650 si añadimos los alóctonos subespontáneos). Para cada taxon se da, tras el nombre admitido en negrita, un listado de sus sinónimos principales. Se aportan datos de ecología, y para muchos táxones su filiación fitosociológica. Se explica su corología general y su distribución aproximada en Cantabria mediante una sectorización, aportando su rango altitudinal y el grado de abundancia. Se dan un listado de citas previas (incluyendo su presencia en herbarios). En muchas ocasiones se aporta un listado de localidades inéditas, y se especifican las novedades florísticas para Cantabria. En este trabajo también se han recogido con detalle los táxones alóctonos a los que se les asigna una tipología (naturalizado, invasor, subespontáneo/adventicio y posiblemente autóctono). Tras el catálogo general se aporta como novedad en este tipo de trabajos, un listado de plantas cultivadas. Le sigue la habitual síntesis florística tras la que se dedica un espacio al listado de nombres comunes regionales. El último capítulo abarca la flora protegida en los diversos niveles administrativos y flora la amenazada. La obra finaliza con los correspondientes apartados dedicados a la amplia bibliografía consultada y un completo índice de familias, especies, y nombres comunes.
The Gnaphalieae (Asteraceae) are a cosmopolitan tribe with around 185 genera and 2000 species. The New World is one of the centers of diversity of the tribe with 24 genera and over 100 species, most of which form a clade called the Lucilia-group with 21 genera. However, the generic classification of the Lucilia-group has been controversial with no agreement on delimitation or circumscription of genera. Especially controversial has been the taxonomic value of achenial trichomes and molecular studies have shown equivocal results so far. The major aims of this paper are to provide a nearly complete phylogeny of the Lucilia-group at generic level and to discuss the evolutionary trends and taxonomic significance of achenial trichome morphology. We conducted a phylogenetic analysis of the New World Gnaphalieae with nrDNA (ETS, ITS) sequence data from a sampling of 18 genera of the Lucilia-group and utilized these results to examine morphological evolution of achenial trichome types and presence of apical myxogenic cells. Seven well-supported subclades can be recognized within the Lucilia-group (L1–L7). These results support Brazilian and Andean Berroa, Facelis, Lucilia, and Micropsis forming a clade (L1), the inclusion of Chilean Lucilia under Belloa (L2), the monophyly of Stuckertiella +Gamochaeta +Gamochaetopsis (L3), Chevreulia +Cuatrecasasiella (L4) and Antennaria (L5) excluding Antennaria linearifolia, which is resolved in a monophyletic group together with Jalcophila, Loricaria and Mniodes (L6), and the recognition of Gnaphaliothamnus (L7) removed from Brazilian taxa of Chionolaena (L2). Ancestral character state reconstruction of achenial trichome morphology suggests that clades are homogeneous in terms of trichome type, but with exceptions that make it highly homoplastic. Conversely, our results suggest that the presence of myxogenic apical cells is less homoplastic and that closely related species tend to resemble each other more than expected under random variation.
The taxonomical complexity of the genus Filago has traditionally led to many determination mistakes which have hampered a precise knowledge of the exact distribution areas of the species included in the genus. We have tried to compile all the available data on the distribution in the Iberian Peninsula and Balearic Islands of 20 taxa from the genus Filago and have critically revised them. As a result, in 13 cases we report the presence of a particular species of Filago for the first time at the provincial level. The distribution ranges of F. gaditana, F. germanica, F. lutescens subsp. atlantica and F. micropodioides traditionally hindered by taxonomic and nomenclatural problems are reliably circumscribed. Last and remarkably, according to our results, F. asterisciflora is not present in the Iberian Peninsula and in the Balearic Islands.
