Notes: FNA7: "Recent molecular data (J. Lihová et al. 2006) indicate that Cardamine umbellata, often treated as a variety of C. oligosperma, represents a distinct lineage more closely related to taxa from New Zealand; this does not exclude C. oligosperma as one of the possible parents of this polyploid."
