Chromosomal evolution in Veronica L. and related genera (Wulfenia Jacq., Wulfeniopsis D. Y. Hong, Paederota L., Lagotis Gaertn., Picrorhiza Royle ex Benth., and Veronicastrum Heist. ex Fabr.; Veroniceae, Plantaginaceae; formerly Scrophulariaceae) is presented. To this end, we conducted an extensive literature survey of more than 400 publications co...

We describe a species of Odontites, O. bolligeri E.Rico, L.Delgado & Herrero, endemic to the south-eastern Iberian Peninsula and north Africa, from Morocco to Tunisia. This species belongs to the O. purpureus group and corresponds to the taxon that the monographer Markus Bolliger called O. squarrosus subsp. squarrosus. However, according to the Int...

Original material for the endemic Iberian species Odontitella virgata, initially described as Euphrasia linifolia sensu Brot., non L., does not exist. A specimen from Valorado's herbarium (LISU) is chosen here as neotype for the name of the species now placed in the monotypic genus Odontitella. The same specimen is selected as neotype for Euphrasia...

Chromosome numbers in 80 populations belonging to 18 species of Potentilla L. subgen. Potentilla from the Iberian Peninsula and two of P. maura, a North African endemic taxon, have been counted. The basic number of chromosomes is always x = 7 and these chromosomes are small (between 1 and 2 μm). For three species, the number of chromosomes is repor...

We show the power of detailed AFLP study to address questions of species delimitation and genetic diversity in morphologically-cryptic plants. We have combined this technique with karyological studies to explore species boundaries in the Western Mediterranean representatives of Veronica subgen. Pentasepalae. Several members of this subgenus are rep...

A multivariate analysis has been performed in order to study the polymorphisms of the three species ofPotentilla sect.Recta (Th. Wolf)Juzepchuk represented in the Iberian Peninsula:P. asturica Rothm.,P. hirta L. andP. recta L. The variability of 20 characters (quantitative, binary and qualitative) has been evaluated in 76 collections mostly from th...

Continuando con las aportaciones al conocimiento de la corología de los helechos presentes en la Cuenca del Duero, se añaden ahora nuevas localidades para 10 pteridófitos escasamente citados o nuevos para las provincias de Zamora y Valladolid. Adiantum capillus-veneris L., Polystichum lonchitis (L.) Roth y Thelypteris palustris Schott son novedad p...
