Author citation (botany)
When citing authors for botanic taxa, the name of the author is often abbreviated, e. g. Agaricus extinctorius L. 1753 for a taxon named by Linnaeus. There is a standardised list of official abbreviations, so that each individual author has a different citation (NB. As most of the people using these pages are probably not botanists and so not familiar with these abbreviations, I have tried to use the full name of the authors - CKT). When a taxon is no longer in the same genus (for species names) or at the same rank (for all taxa), the name of the original author is placed in brackets and followed by the author who assigned the new combination or rank, e. g. Prunulus extinctorius (L.) Gray 1821. Generally, the date of publication is only given when specifically dealing with taxonomy and is otherwise omitted.
