List of botanists by author abbreviation (A)
This is a list of botanists by their author abbreviation, including that established by Brummitt & Powell (1992), designed for citation in the botanical names they have published. For this purpose a standardised index is available, published by the Royal Botanic Gardens, Kew in 1992. Use of this list is recommended by Rec. 46A Note 1 of the ICBN. The list is kept up to date and can be consulted at IPNI.
Note that in some cases an "author abbreviation" consists of a full surname, while in other cases the surname is not only abbreviated but accompanied by one or more initials. In this list there is no space between initials and surname (or its abbreviation).
