Abstract

The Merton Catalogue NOTE The chromosome number given in all cases is zn. References. Usually the latest is given, or, if not, the more important one. In some cases European works are preferred. (A) refers to article on apomixis. (G) refers to article on genetics. (S) refers to article on systematics. (T. 1927, T. 1931), etc., refers to Tischler's lists of chromosome numbers when the information is given there and not otherwise published. The basic number {x) is given after the genus. Many genera are dibasic, (apo) after a genus means that it is apomictic. The nomenclature used is that of the London Catalogue, eleventh edition (1925). A certain number of corrections and additions have, however, been made at Kew. These bring the list more into line with recent work, but no attempt has been made to render it fully correct, either taxonomically or nomenclaturally. A new Students' Flora is in course of preparation, and it was considered unwise to attempt extensive corrections in the London Catalogue names pending its publication. Where the cytological author uses a different name this is given in square brackets, e.g. [as triviale Link.]. Where the eleventh edition of the London Catalogue uses a different name this is given in round brackets, e.g. {Boreana Jord.). A or B after the number of a genus, e.g. 520 A Pholiurus, indicates that the genus has been subdivided and that Pholiurus does not appear in the London Catalogue. Uncounted species are arranged alphabetically. The rest are arranged primarily by chromosome number, secondarily in alphabetic order. The numbers are taken in ascending order, except where there are two or more clear series, e.g. multiples of 7, 8, and 9 in Veronica. 1. CLEMATIS x = 8 Vitalba L. 2.
