"IndExs - Index of Exsiccatae" is a bibliography of exsiccatal series. With more than 2050 data entries it is nearly complete. "IndExs" comprises information on titles, abbreviations and bibliography of exsiccatae. Exsiccatae are defined here as "published, uniform, numbered sets of preserved specimens distributed with printed labels" (Pfister 1985). The single search result gives you all bibliographically important information on the series: the editor(s), title in its bibliographical correct form, standardized abbreviation of the series as to cite in specimen lists of scientific papers or to add in your collection management system, the place of publication and the group(s) of organisms distributed. Additionally, the first and last number of the series as well as the corresponding year of the first and last issue are mentioned. Where preceding and / or superseding series do exist this information is linked. Images of single examplary labels are included for 60% of the series. They are taken from material located in more than 20 public herbaria worldwide.
The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of all seed plants, ferns and fern allies. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. The data are freely available and are gradually being standardized and checked. IPNI will be a dynamic resource, depending on direct contributions by all members of the botanical community. IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium
