The status of this species has been controversial, usually being subordinated to the widespread R. phyteuma. A study of R. collina and allied taxa based on morphological and molecular (nuclear ITS, plastid trnL-F) data supports the taxonomic identity of R. collina and its separation from R. phyteuma. An epitype is designated to support the holotype and prevent future nomenclature problems. In addition, our molecular and morphological analyses suggest that some problematic southeastern Iberian populations, previously identified as R. phyteuma, belong to R. collina, which implies a new European record for this species that was previously considered as a northwestern African endemic. Following this finding, biogeographic relationships between the southern Iberian Peninsula and northwestern Africa are also discussed.

No. 629.4, LINN) of Reseda glauca L. is identifiable as the related species, R. virgata Boiss. & Reuter. The specimen, collected by Löfling in central Spain, was not explicitly cited in Linnaeus's protologue, in contrast to a specimen (at UPS) collected by Burser in the Pyrenees and identifiable as R. glauca of usage. In accordance with Art. 9.10 of the ICBN, we reject the choice of 629.4 (LINN) as lectotype and we designate Burser's specimen as the lectotype of R. glauca L. in its place. This type choice maintains the traditional and current usage of this well-known and widely used Linnaean name.

Recent collections confirm its presence in wetlands of southern Spain and Morocco. We consider the presence of this plant in the western extreme of the Mediterranean as a consequence of recent colonization, because it was not collected here until 1999, in spite of its mediumÁlarge size. Additionally, it grows in much visited areas like nature reserves (such as Doñana National Park). The populations from Spain and Morocco are characterized here, a description of S. corymbosus and a key for Schoenoplectus from Europe and north Africa is supplied. Finally, the possible natural and recent colonization processes of these new populations are discussed.
