Iittorale (D. Turner) Gilmour subsp. Iittorale has shown that both show a wide range of morphological variation. Much of this variation is retained in cultivation and five varieties are recognized of subsp. erythraea and four of subsp. Iittorale. Despite this variation the two subspecies are quite distinct. Analysis of mixed populations of the two species from the coasts of Anglesey and Lancashire has shown tbat some plants are, to varying degrees, intermediate and probably of hybrid origin. In the majority of populations from the Lancashire coast, backcrossing to C. [ittorale appears to have taken place, although two suggest backcrossing to C. erythraea. This is in contrast to the situation in the population from Anglesey in which only F.-like hybrids were present. Analysis of two populations from northern Germany show all plants to be intermediate and F.-like."

Melderis [Espèces (in biblio)] Centaurium littorale Mots-clés : Centaurium erythraea Rafn subsp. erythraea var. subcapitatum Résumé : "Chromosome counts of Celllallrium erythraea Rafn and C. littorale (D. Turner) Gilmour from northern Europe are given. They confirm those made by Zeltner (1970) and show both species to be tetraploid (211 = 40) with regular meiosis. Morphologically intermediate (Ft-like) plants from Ainsdale, S. Lancs. (v.c. 59), were found to be tetraploid with irregular meiosis. They were almost sterile, as were Ft-like plants from Newborough, Anglesey (v.c. 52), and were almost identical in their morphology and cytology to artificial Fl hybrids. Morphologically intermediate plants from northern Germany were found to be tetraploid, but with regular meiosis and a high fertility. It is suggested that they are stabilized derivatives of the F 1 hybrid. Hybrid plants from St Annes, W. Lancs. (v.c. 60), which resemble C. erythraea in their morphology and are probably backcrosses to this species, were found to be tetraploid with regular meiosis and a high fertility. Hybrid plants from Ainsdale, Freshfield and Hightown, S. Lancs. (v.c. 59), which closely resemble C. littorale in their morphology, were found to be hexaploid (211 = 60) with regular meiosis and a high fertility. They are shown to breed true, to be isolated from their tetraploid parents and other (tetraploid) hybrids by a difference in chromosome number, and to be able to compete successfully with their parents. They are, therefore, considered to constitute a new species, and a possible origin involving hybridization and polyploidy is discussed."
