In addition, the lectotypes of B. longifolia and B. balearica f. granatensis, currently treated as two heterotypic synonyms of B. balearica, are designated from original material preserved at G-BOIS and MA, respectively

Filling such knowledge gap is necessary to optimize conservation management, specially for species occurring in vulnerable ecosystems such as Southern European mountains. Campanula sect. Heterophylla is a complex group with a high proportion of endemic taxa in European mountain ranges, and whose species delineation is often controversial due to extensive morphological variation. We investigated the phylogenetic relationships and evolutionary entity of its taxa occurring in the Pyrenees, with a special focus on the Pyrenean endemic C. jaubertiana (which is sometimes included as a subspecies of or merged with C. cochleariifolia ); and C. andorrana , a taxon allegedly endemic to Andorra (Eastern Pyrenees) and of uncertain taxonomic value. We obtained chloroplast genome and nuclear ribosomal DNA sequences, including several individuals of the three focus taxa, and conducted morphometric analyses. Phylogenetic analyses show that C. jaubertiana sensu lato (s. l.; i.e. including C. andorrana ) constitutes a clearly distinct lineage that is not even closely related to C. cochleariifolia ; consistent differences in floral morphology were detected between them. Our results support two main evolutionary lineages within C. jaubertiana s. l., one corresponding to populations in Central Pyrenees, and another one in Eastern Pyrenees plus Catalan Pre-Pyrenees. Given the degree of genetic and morphological differentiation, we propose the species rank for each lineage ( C. jaubertiana and C. andorrana, respectively) and provide a taxonomic treatment. These two Pyrenean endemics likely diverged through transverse allopatric speciation.

The new species is closely related to the Iberian L. hibericum on morphological traits as assessed by multivariate ordination analysis (PCA), but it can be distinguished by the narrower leaves, inflorescence shape, and longer calyx. Limonium ilergabonum shows mixoploidy (2n = 18, 2n = 27), irregular pollen shapes, low levels of pollen stainability, and a single pollen-stigma combination morph (B type). All evidences suggest that L. ilergabonum is a polyploid relict species with an apomictic breeding system that has been originated from 2n = 18 ancestors, but to date any known extant diploid species may be suggested as a likely parental species.

These are distributed from the Macaronesian-Mediterranean region to southern Africa, India, and China (Morales 1991b, Govaerts 1999, Harley et al. 2004, Bräuchler et al. 2005, 2008; Puppo & Meimberg 2015, Puppo et al. 2014, 2015).

In addition, new local records are provided for ten taxa scarcely reported for Catalonia. During the last decades, ornamental horticulture constitutes the most important source of alien plants, and some of them are potentially invasive species at a worldwide level. Most of the plants listed in this study are escaped from gardens or established as a consequence of dumping green waste. Some species are locally naturalized and in some cases they could behave as invasive.
