IndExs – Index of Exsiccatae

IndExs – Index of Exsiccatae is an online biological database that plays a pivotal role in documenting more than 2,400 historical and ongoing series of exsiccatae and exsiccata-like works. Managed by the Botanische Staatssammlung München in München, IndExs serves as a comprehensive data repository for these series, acting as directory providing detailed titles with information on the more than 1,300 editors, bibliographic information, exsiccatal numbers, publication timespans, ranges, information on preceding and superseding series and publishers. Exsiccatae, organised series of biological specimens distributed among biological collections, are essential resources found in major herbaria worldwide. Open access to the general information on exsiccatae facilitates global scientific engagement and research. The database tells surprising stories on the common cultural history of taxonomic collections worldwide as well as on the persons and organisations involved in plant specimen exchange and trade projects.
