Cano-Maqueda, J. & Talavera, S. 2011. A taxonomic revision of the Campanula lusitanica complex (Campanulaceae) in the Western Mediterranean region. Anales Jard. Bot. Madrid 68(1): 15-47. The systematics of the annual species of the Campanula lusitanica complex in the Western Mediterranean is reviewed using ITS sequences, karyology and morphology of all species of the complex. The information provided by these three sources is consistent, and the species are reorganized into two groups with the rank of section: Campanula sect. Rapunculus Boiss. and Campanula sect. Decumbentes, the latter described as new in this work. These sections comprise two well-defined subclades in the phylogenetic analyses. Sect. Rapunculus is composed, in the W Mediterranean region, by C. lusitanica L. and C. matritensis A. DC., both with 2n = 18 chromosomes, and C. cabezudoi Cano-Maqueda & Talavera, C. specularioides Coss., C. transtagana R. Fern., and C. broussonetiana Schult., all with 2n = 20 chromosomes. In the Iberian Peninsula, Sect. Decumbentes comprises two endemic species, C. decumbens A. DC. with 2n = 32 chromosomes and C. dieckii Lange with 2n = 28 chromosomes. In C. decumbens a new subspecies is described: C. decumbens subsp. baetica Cano-Maqueda & Talavera, which occurs in the Guadalquivir valley. In the formal systematic part we provide a key to identify these annual species of the Western Mediterranean, with a description and typification, photographs of flowers and fruits, distribution maps, and comments on the habitat for each taxon.
