This book is an addendum to the series of Angiosperm leaf species names. During work on leaf impressions/compressions the need for an index of names and descriptions of angiosperm leaf species became evident. It also was of value to know where, when and by whom they were created or used. Therefore, this index was made, centred on the literature available in the Netherlands and focusing on the northern hemisphere. It is updated up to 2016.
Although it is clear that such a list will never cover all published names it is nevertheless hoped that this index may lead to a more easy approach of the literature on leaf impressions/compression fossils and the avoidance of the creation of homonyms. During the publication of the foregoing issues several new and also older publications were brought to the attention of the author, they were used in the more recent issues but could not be entered in the foregoing issues. These names are given in this list of addenda. Consequently, the names from the beginning of the alphabet are more numerous than those of the last part of it.
In this index only genera and species are treated, taxa of minor order are not included. The species are listed in alphabetical order and the literature is cited in chronological and alphabetical order. Publications giving only listings of species without comment are omitted; only publications with a description or a illustration are used. Also, use is made of earlier indexes, especially from North America. When descriptions are given in more than one publication of an author of a combination of authors, the later publications are listed chronologically behind the first one without repeated citing of the name(s) of the author(s). The original description is marked with an asterisk behind the publication. When the original description is repeated in later publications, these are also marked with an asterisk.
