The database itself and its web interface have been built by Jan Hnilica, without whose dedication and interest the database would have never attained the present shape.

Support during building the database from 1994 was provided by Institute of Botany, Academy of Sciences of the Czech Republic (grants AV0Z6005908, AV0Z60050516, RVO 67985939), Grant Agency of the Czech Republic (grants 206/01/1039, 22-10897S) and by the European Commission (LEDA project under ESSD programme, contract number EVR1-CT-2002-40022) and several additional research grants.
