The white-flowered form of the Asian species Corydalis buschii Nakai (Fumariaceae) is for the first time found in the Ussuriysky Nature Reserve (southern Russian Far East) and described as a new one. Long-term (2005-2015) observations allow to state that this population of C. buschii is very stable and developing successfully. The plants give flowers and fruits annually.
