Degenia
Degenia is a monotypic plant genus in the mustard family containing the single species Degenia velebitica . The yellow-flowered plant is endemic to Velebit and Kapela mountain ranges, and has become a symbol of the region.
Discovered by Dr. Àrpàd Degen on 17 July 1917, the Degenia velebitica is depicted on the reverse of the Croatian 50 lipa coin, minted since 1993.
