Floral nectar spurs are widely considered a key innovation promoting diversification in angiosperms by means of pollinator shifts. We investigated the macroevolutionary dynamics of nectar spurs in the tribe Antirrhineae (Plantaginaceae), which contains 29 genera and 300-400 species (70-80% spurred). The effect of nectar spurs on diversification was...

A new nomenclatural combination Linaria amethystea subsp. albiflora and a new taxa L. amethystea subsp. toloxense are proposed. The relationships of both taxa with the rest of subspecies of L. amethystea present in the south of the Iberian Peninsula are clarified an identification key for all the subspecies recognized in the Iberian Peninsula withi...
Linaria vettonica Luceño, Mazuecos & P. Vargas, a new species of Linaria sect. Supinae, is described. It is a narrow endemic inhabiting the southern hills of the western and central massifs of Sierra de Gredos (Sistema Central mountains, Iberian Peninsula). The five populations found occur on siliceous, sandy soils of Quercus pyrenaica woodland cle...
Integrative taxonomy, based on the combination of multiple lines of evidence, provides the foundations for a robust species delimitation. Here we provide a taxonomic synopsis of the Iberian clade of Linaria subsect. Versicolores based on recently published morphometric and phylogenomic data. This clade radiated in the Iberian Peninsula (western Med...
BACKGROUND AND AIMS: Nectar spurs (tubular outgrowths of a floral organ which contain, or give the appearance of containing, nectar) are hypothesized to be a 'key innovation' which can lead to rapid speciation within a lineage, because they are involved in pollinator specificity. Despite the ecological importance of nectar spurs, relatively little ...

Disentangling species boundaries and phylogenetic relationships within recent evolutionary radiations is a challenge due to the poor morphological differentiation and low genetic divergence between species, frequently accompanied by phenotypic convergence, interspecific gene flow and incomplete lineage sorting. Here we employed a genotyping-by-sequ...

In this paper, a new Polish record of Linaria genistifolia is presented. It was found on 27 August 2017 in Zabrze, Silesia Province, growing at the foot of the reclaimed slag heap. The updated map of its distribution in Poland is provided using the ATPOL cartogram method.
Se describe Linaria × jalancina Gómez Nav., R. Roselló, A. Guillén, P. P. Ferrer, E. Laguna & J. B. Peris (Plantaginaceae), un nuevo híbrido natural, fruto del cruce entre L. arvensis (L.) Desf. y L. simplex Willd. ex Desf., que se ha hallado en la provincia de Valencia, cerca del límite con la provincia de Albacete (E de España). Se proporciona un...
