It includes, apart from the general collection, other historical collections (from 17th to early 20th century). The main objectives of this study were to evaluate if the endemic and threatened taxa of Catalonia are represented in the herbarium. We also provide chronological and geographical information of herborization intensity, as well as altitudinal, chorological, chronological, phenological and over-collection risk new data. We analyzed the general collection and part of informatized historical herbaria (Cadevall, Hieraciotheca Gallica et Hispanica, Institucio Catalana d’Historia Natural, Salvador, Societat Botanica Barcelonesa ...

Catalonia is an administrative region of Spain that includes large autochthon plants diversity and 199 taxa with IUCN threatened categories (EX, EW, RE, CR, EN and VU). This dataset includes 1,618 records collected from 17th century to nowadays. For each specimen, the species name, locality indication, collection date, collector, ecology and revision label are recorded. More than 94% of the taxa are represented in the herbaria, which evidence the paper of the botanical collections as an essential source of occurrence data.

La seva contribució a l’estudi de les pastures el va convertir en un referent per a l’ecologia terrestre, però els que signem aquesta nota, botànics de formació, no podem deslligar la figura del Dr. Montserrat de l’herbari JACA, un dels més voluminosos de l’estat espanyol i que tantes vegades hem tingut com a referència i que ell creà i començà a alimentar amb materials procedents de les seves recol·leccions primerenques —d’ara fa 70 anys— en territori aragonès o ibèric en general. El lligam del Dr. Montserrat amb l’Institut Botànic de Barcelona (IBB) i la Un...

El primero es una memoria razonada sobre un proyecto de Flora Hispanica, con evaluacion de los recursos necesarios para realizarla. El segundo, un modelo de tratamiento de la familia de las Solanaceas con el genero Atropa a modo de ejemplo. Una breve introduccion historica permite situar al autor ya su proyecto en su epoca.

Mostrem estadistiques sobre els recol·lectors, els anys i les localitats de recol·leccio, les families i els grups taxonomics representats, aixi com una llista de plecs tipus i altres exemplars d?interes taxonomic. En l?estat actual, l?herbari consta de 1.202 plecs. Es constituit, gairebe en la seva totalitat, per plantes cedides per la familia de Frederic Tremols i per part de l?exsiccata «Plantes d?Espagne» del germa Sennen. Els materials procedeixen principalment de Catalunya (532 plecs, un 44 %), de la resta de l?Estat espanyol (218, un 18 %) i del continent europeu (125, un 10 %), i inclouen una proporcio de cruciferes poc habitual en els nostres herbaris (253, un 21 %). D?altra banda, dels 112 plecs tipus presents en l?herbari, ben pocs taxons son reconeguts en flores actuals, com l?Achillea millefolium L. subsp. ceretanica (Sennen) O. Bolos & Vigo o l?Eryngium × chevalieri Senn...

A complete and annotated catalogue of names by Pau for Moroccan taxa is presented here. For all of them, the typification and synonymy have been evaluated. For 63 taxa the holotype is indicated, and 206 taxa are typified here. The main collection of Pau and most types are preserved in Herb. MA, but many types have also been found in Herb. BC and other European herbaria.

O... more Invasive alien species are currently considered one of the main threats to global biodiversity. One of the most rapidly expanding invasive plants in recent times is Kalanchoe × houghtonii (Crassulaceae), an artificial hybrid created in the 1930s in the United States by experimental crossings between K. daigremontiana and K. tubiflora, two species endemic to Madagascar. Thanks to its large colonizing capacity (mainly derived from the production of asexual plantlets), K. × houghtonii soon escaped from cultivation and quickly spread in many parts of the world. However, its actual range is not well known due to the lack of a formal description until recent times (2006) and its strong morphological resemblance with one of its parentals (K. daigremontiana). The present study was aimed, in the first instance, to delimit the present distribution area of K. × houghtonii at the global scale by gathering and validating all its occurrences and to track its colonization history. Currently, K. × houghtonii can be found on all continents except Antarctica, although it did not reach a global distribution until the 2000s. Its potential distribution, estimated with MaxEnt modelling software, is mainly centered in subtropical regions, from 20° to 40° of both northern and southern latitudes, mostly in areas with a high anthropogenic activity. Unexpectedly, concomitant to a poleward migration, future niche models suggest a considerable reduction of its range by up to one-third compared to the present, which might be related with the Crassulaceaean Acid Metabolism (CAM) of K. × houghtonii. Further research may shed light as to whether a decrease in potential habitats constitutes a general pattern for crassulaceae and CAM plants.

In the present paper, 63 names of Hieracium are treated. In order to fix their applications, nomenclatural types for 28 Pau’s names in the genus Hieracium are designated (27 lectotypes, 1 neotype and 1 epitype). All the type material available is listed with full label data, and some nomenclatural and taxonomic comments are provided.

Ten lectotypes have been designated; most of them preserved in MA and BC herbaria (isolectotypes at BCN, G, LD, and P).

Since their creation, their uses have dramatically expanded and with many new uses being proposed, including some for which herbaria were not initially intended for. In this paper we assess the potential of these collections on conservation biology, by providing exemplary studies that use herbarium specimens, grouped into four categories: (1) based on occurrence data, such as studies about plant extinction or introduction, or those focused on modelling their ecological niche; (2) based on the specimens themselves, such as morphological or phenological studies to evaluate the impact of climate change; (3) based in genetic data, such as phylogeographic or taxonomical studies; and (4), other applied studies. Resumen Las colecciones de herbario constituyen un registro permanente y a menudo bien documentado de la distribución de los taxones a lo largo del espacio y el tiempo. Desde su creación, sus aplicaciones se han diversificado de forma considerable, y recientemente han emergido nuevos usos, algunos no contemplados originalmente. En este trabajo evaluamos el potencial de estas colecciones para la biología de la conservación, a partir de algunos ejemplos de estudios que usan especímenes de herbario, agrupados en cuatro categorías: (1) basados en datos de presencia, como por ejemplo estudios sobre extinciones o introducciones de plantas, o modelizaciones del nicho ecológico; (2) basados en los propios especímenes, tales como estudios morfológicos o fenológicos para evaluar el impacto del cambio climático; (3) basados en datos genéticos, como por ejemplo estudios filogeográficos o taxonómicos y (4) otros estudios aplicados.

Most current ethnobotanical research is focused, especially in industrialised countries, on obtaining information of plant uses from elderly people. Historical ethnobotany is less cultivated, although papers have demonstrated its interest. Particularly poor, but potentially very relevant, is the attention paid to historical herbaria as a source of data on useful plants. Aims of the study: Bearing this in mind, we studied the herbarium of the Catalan pharmacist and naturalist Francesc Bolòs (1773-1844), which contains information on medicinal uses and folk names, with the aim of establishing a catalogue of plants and uses and tracing them through old and contemporary literature. Methodology: The ca. 6,000 plant specimens of this herbarium were investigated to assess those including plant uses and names. These taxa have been thoroughly revised. The data have been tabulated, their biogeographic profile, possible endemic or

The digitization of this historical collection, currently in progress, has made possible to locate nomenclatural types of various authors, acquired through exchange. In this article, we indicate two syntypes (for Fumaria caespitosa Loscos and Carex loscosii Lange), and one isolectotype (Polygala vayredae Costa) in Trèmols herbarium. Additionally, we designate the lectotype of Polygala vayredae in the Costa herbarium and its isolectotype in the Vayreda herbarium.
