The abbreviations used are in general in conformity with common usage in botanical taxonomy, though, where possible, the citation has been limited to the minimum necessary for strict taxonomic reference, e.g.: ‘F.v.M. Fragm.’—for F. VON MUELLER, Fragmenta phytographiae Australiae, ‘Walp. Ann.’—for Walpers, Annales, ‘BAILEY, Compr. Cat. Q. Pl.’—for F. M. BAILEY, Comprehensive Catalogue of Queensland Plants. ‘In’ after the author’s name has been used only if one author has published in the work of another author, e.g.: ‘BENTH. in B. & H. Gen. Pl.’, ‘CLARKE in Hook. f. & Th. Fl. Br. Ind.’, or in the serial which, for the sake of clearness should be preceded by the name of its editor, e.g. ‘SCHLTR in Fedde, Rep.’; ‘Rep.’ alone would not be sufficient, since there are several repertoria.
