This paper describes the herbarium (COFC) dataset of vascular plants of the University of Cordoba (SW Spain). This dataset is made up of two collections, the General collection (61,377 specimens) and the Historical collection (1,614 specimens). This study has focused mainly on the General collection, which contains the largest number of vascular plant specimens, predominantly angiosperms, mainly provincial and regional (Andalusia, Spain), but also with a good representation of other areas of the Iberian Peninsula and neighboring countries. The place of collection is specified in 99.7% of the labels, about 35% being georeferenced, and it is estimated that, currently, about 86% of the material housed in the herbarium has been databased using Elysia v1.0. software. With more than 178 families, 1,178 genera, and 3,750 species, this collection not only has educational importance, but is a valuable research tool that has been useful for the development of important works such as "Flora Vascular de Andalucía Occidental" and the "Flora iberica". The dataset described in this paper is registered with GBIF (accessible at https://doi.org/10.15468/fdzzal).

Based on our study of 4,845 herbarium sheets of the genusPoafrom the area covered byFlora iberica, namely, the Iberian Peninsula and the Balearic Islands, we recognise 24 taxa (17 species, 1 subspecies and 8 varieties), mostly perennials. Most of these taxa have wide global and/or European distributions, while two (P.legionensisand P.minorsubsp.nevadensis) are Spanish endemics and two have restricted distributions (P.ligulata, Iberia–North Africa;P.flaccidula, Iberia–North Africa and the Balearic Islands, extending to Provence, France). We have studied the original publications of more than 225 names considered as synonyms, with those more historically cited inFlora ibericataken into account in this paper; a total of 26 are new synonyms. The following names are typified: P.alpinavar.involucrata Lange, P.annuavar.lanuginosa Sennen, P.minorsubsp.nevadensis Nannf.,P.pauiFont Quer,P.sulcataLag. and P.trivialisvar.flaccida Willk. ex J.J. Rodr. We includeP.compressaL. in the flora of Portugal for the first time and present detailed illustrations of three very interesting taxa (P.legionensis, P.minorsubsp.nevadensis andP.ligulata). In addition to a general species key, we provide the following information for each taxon: synonyms, types, typification, the most relevant iconography, regional flowering time, regional and general distribution and, as supplementary material, the number of sheets examined and a list of selected materials.

A new species, Festuca greuteri, from the southeast of the Iberian Peninsula (Spain) is described. The new taxon is recognised with two patterns of variation with the rank of subspecies: subsp. greuteri, widely distributed throughout the Baetic Mountains (Almería, Granada, Jaén and Málaga provinces, southern Spain), and subsp. camarolensis, located in the westernmost area of distribution, in the Sierra de Camarolos and Sierra del Jobo (Málaga province, southern Spain). This species belongs to Festuca sect. Festuca, and it had been overlooked or misidentified as F. segimonensis and F. longiauriculata, two species that are partially sympatric with it. Herbarium specimens and living plants were analysed, and noteworthy morphological and anatomical differences support their separation. A complete description is presented for the new species, and iconography and identification keys are provided together with information on leaf anatomy, ecology, phenology, and distribution. The new species is compared with the related species occurring in the southeastern Iberian Peninsula, and differential characters are discussed.

Two new species of the genus Galium are described from the Iberian Peninsula: G. moralesianum OrtegaOlivencia & Devesa, and G. talaveranum Ortega-Olivencia & Devesa. The first grows on limestone or dolomiticlimestone outcrops in south-east Spain (the Segura and Gador mountain ranges) and shows morphological similarities with G. boissieranum Ehrend. & Krendl, which is endemic to southern Spain (mountains of Malaga). The second inhabits the margins of water courses, alder stands and cork-oak dehesas (parkland-type systems) of the west of the Iberian Peninsula, and is morphologically reminiscent of G. mollugo L. The chromosome numbers of these two species and of G. boissieranum are given. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 143, 177–187.

A taxonomic revision of the species of the Festuca marginata group on the Iberian Peninsula is presented. Traditionally, this group has included several taxa of Festuca sect. Festuca characterized mainly by having three strands of sclerenchyma in the leaf blade and whose delimitation is difficult. To clarify taxonomy of this group, a morphological, anatomical, chorological and ecological study was performed on 246 specimens from herbaria and wild populations, and 21 morphological and anatomical characters were studied biometrically in 72 specimens from 65 different locations. A new taxonomic treatment of the group is derived from the results of the analyses. Festuca marginata, a species distributed over the east and northeast of the territory, is recognized with two subspecies: subsp. marginata, which is widely distributed in France but has a restricted distribution in the Pyrenean area, and subsp. andres-molinae, endemic in the east and northeast of the Iberian Peninsula. Festuca lambinonii, widely distributed in the mountains of the centre, east and northeast of the territory, is also recognized. An identification key, descriptions, synonyms, distribution, phenology, and ecology data are provided for the three taxa recognized.

Gilbertiodendron grandistipulatum (Leguminosae-Caesalpinioideae), una especie singular del centro-oeste de África y nuevo registro para Congo (Brazzaville). Gilbertiodendron (Leguminosae-Caesalpinioideae) es un género endémico de África con ca. 30 especies, las cuales en su mayor parteson árboles que crecen en bosques primarios. El mayor número de especies y la mayor variabilidadmorfológica se encuentra en la región Guineo-Congoleña, y el particular en Gabón. Una de esasespecies es G. grandistipulatum, que se reconoce fácilmente por sus estípulas (de hasta 18 cm delongitud) y flores (con pétalos adaxiales de hasta 12,5 × 14 cm). En el presente trabajo se discute lataxonomía, hábitat y distribución de G. grandistipulatum, extendiendo su área de distribución a Congo.Se proporciona una descripción completa, un mapa de distribución y dos iconografías por primera vezpara esta especie.

El género Carduus L. (Cardueae, Asteraceae), tal y como se considera hoy día, comprende unas 90 especies eurasiáticas (Susanna & García-Jacas, 2007), con especial representación en la Región Mediterránea (Kazmi, 1964). Su conocimiento en la Península Ibérica se fundamenta, sobre todo, en las revisiones taxonómicas de Willkomm (1865 & 1893), Kazmi (1963), Franco (1975) y Devesa & Talavera (1981 a & c), y en la información cariológica (Fernandes & Queirós, 1971; Devesa & Talavera, 1981 b; Rosselló et al., 2005), palinológica (Tormo & Ubera, 1988) y sobre diversos aspectos reproductivos de algunos de sus táxones (Devesa & Talavera, 1981 c). Sobre la base de esta información, el género se consideraba representado en la flora peninsular por 19 especies, siendo 26 el número de táxones reconocidos (Devesa & Talavera, 1981 c) sin contar los híbridos, frecuentes también en el territorio. No obstante, al revisar el género –J. A. Devesa– para la obra Flora Iberica (coord. S. Castroviejo), se han encontrando novedades de interés, entre las que cabe destacar la presencia en la flora española de C. acicularis Bertol., cuyas características y afinidades con especies próximas se comentan a continuación. El estudio morfológico y biométrico en el que se fundamenta este trabajo ha sido llevado a cabo en material recolectado por los autores y en el conservado en diferentes herbarios (BC, BCF, COA, COFC, COI, COI-WILLK., JACA, K, LISU, LTR, MA, MAF, MGC, SEV, UNEX).

Madrid 55(2): 245-260 (in Spanish). Ononis reuteri Boiss. is considered to be a good species, clearly different from O. aragonensis Asso, and its presence in North Africa is confirmed. O. hispanica L. f. is regarded as a nomen ambiguum, which should not be used. The classification of the O. natrix L. group is discussed and a new species of this group, O. talaverae Devesa & G. Lopez, is described. O. crispa L., to the Balearic Islands endemic, is excluded from the Iberian Peninsula flora. O. tridentata L. is typified. O. saxicola Boiss. & Reut. is considered to be merely a subspecies of O. pusilla L. The new combinations O. tridentata susbp. angustifolia (Lange) Devesa & G. Lopez and O. pusilla var. calycina (Rouy) Devesa & G. Lopez, are proposed.

Centaurea stuessyi is described as new to science from the eastern Iberian Peninsula, Spain. The range of this new species coincides with the zone of overlap of the ranges of two related species, C. antennata (subsp. antennata ) and C. linifolia . The chromosome number found in the new species (2 n = 44) reinforces its differences from C. linifolia (2 n = 22) and C. antennata (2 n = 22). The new species is compared with related species, and a description is given of its ecological preferences.
