Description of the interactive multiple-entry polyclave electronic key for identification of 102 species and subspecies of Siberian Astragalus is presented. At every step of identification, the program reduces the species list, reduces the state lists for qualitative characters, recalculates diagnostic values of characters and ranks the characters by their diagnostic value. In the process of identification, a user can return to previous steps of identification, to get text descriptions and drawings of a species and the photos of herbarium specimens, to use an interactive monoentry dichotomous key, to change and input new data into the data table. The program is workstation-based and implemented in Microsoft Access 2002.
