Major changes in the diagnosis, taxonomy and chorology of Cantabrian brooms with glabrous calyces and pubescent legumes, classified as sect. Spartopsis of the genus Cytisus (Fabaceae), have been recently implemented. Two species of this section occur in the Cantabrian region: Cytisus cantabricus and C. grandiflorus. A detailed study of the plants u...

:The variability of Viola palustris, s.l. in different localities of Asturias, León and Lugo is studied. We show that Viola palustris subsp. juressi Link ex Wein can be recognized morphologically and moreover lives biogeographic and bioclimatically separate of the typical subspecies.

Fifteen accessions of Festuca group rubra collected in northern Spain were characterized and grouped into four Festuca taxa on the basis of leaf anatomy, morphology and ploidy; seven were identified as F. heteromalla; two as F. trichophylla ssp. asperifolia; two as F. nigrescens ssp. microphylla and four as F. rubra ssp. pruinosa. All the accession...

The fluorescence properties of spores and pollen grains examined under ultraviolet incident light are used to assess the maturity of sedimentary organic matter and may have other applications in relation to recent sediments, in areas such as palaeoenvironmental research. In this study pollen grains and spores from 33 species common in peat ecosyste...

The westernmost corner of the Cantabrian Range (NW Spain) is a territory of good possibilities for palaeoecological reconstructions. Nevertheless, vegetation dynamics in this area is still imprecise, mainly because the available environmental data are scarce, particularly those regarding its northern façade. New pollen and radiocarbon data obtained...

ABSTRACT. Pollen malformation and ploidy levels in Ranunculus grex parnassiifolius. A survey of pollen malformation in Ranunculus grex parnassiifolius, a polyploid complex distributed from the northwestern mountains of the Iberian Peninsula to the most alpine massifs, is presented. The most remarkable result is the low viability of pollen in tetrap...

Detailed knowledge of the spatial distribution of sources is a crucial prerequisite for the application of pollen dispersion models such as, for example, COSMO-ART (COnsortium for Small-scale MOdeling - Aerosols and Reactive Trace gases). However, this input is not available for the allergy-relevant species such as hazel, alder, birch, grass or rag...

The taxonomy and nomenclature of the genus Huperzia Bernh. in the Azores and Madeira have been reviewed. Plants collected in the Azores and Madeira were characterized morphologically. The independence between two endemic species common to Madeira and the Azores Islands –Huperzia suberecta (Lowe) Tardieu and Huperzia dentata (Herter) Holub – is clea...

BUENO SANCHEZ, A., FERNANDEZ CASADO, M. A., FERNANDEZ PRIETO, J. A., 1992. A new subspecies of Ranunculus parnassiifolius L. (Ranunculaceae) from the Cantabrian Mountains, Spain. Specimens of Ranunculus parnassiifolius not easily matched with any of the known subspecies were collected in the Western Cantabrian Mountains (Biological Reserve of Munie...

Data on twelve taxa of the Cantabrian Flora little known, or recorded for the first time, from Asturias, León and Cantabria are given.

A checklist of the natural, sub-spontanous and cultural (excepting the ornamental) flora of Asturias, containing more than 2000 taxa, is presented. Phytosociological relations are also given. -English summary

García-Mijangos, I. los alcornocales del sector Castellano-Cantábrico. Lazaroa 15:241-244 (1994). Se describe una nueva subasociación del Spiraeo obovatae-Quercetum rotundifoliae, correspondiente a los alcornocales del sector Castellano-Cantábrico.

The variability of Viola gr. silvestris in Asturias is studied. The presence of V. reichenbachiana Jord. ex Boreau in Iberian Peninsula is confirmed. Se estudia la variabilidad de Viola gr. silvestris en Asturias. Se confirma la presencia de V. reichenbachiana Jord. ex Boreau en la Península Ibérica.

È stata condotta un’analisi sul comportamento ecologico di Festuca bumatii St. Yves, attraverso lo studio di due microhabitats (A, cornici rocciose e fessure profonde e B, terreni scorticati) in diverse località della cordigliere Cantabrica. Per una migliore comprensione, viene elencata una sintesi degli inventari fitosociologici prelevati dalle di...

The European arosulate species of the genus Viola subsection Rostratae are revised. Viola abulensis Fdez. Casado & Nava, sp. nov., is described. A key to the identification of the taxa is given. Se estudian las especies europeas sin roseta del género Viola subsección Rostratae, se describe Viola abulensis Fdez. Casado & Nava, sp. nov., y se da una...

After studying the pollen fertility and the indument of the leaves, a new status for Helianthemum urrielense (Laínz) Nava & Fdez. Casado is proposed. Tras haber estudiado la fertilidad polínica y el indumento foliar, se propone el "status novus" Helianthemum urrielense (Laínz) Nava & Fdez. Casado.
