Notes: Established occurrence of Tripleurospermum inodorum in the Arctic remains to be documented, most probable in northern Norway. This probably constantly tetraploid species differs in several unrelated characters from the probably constantly diploid T. maritimum. Sterile hybrids are reported (Hämet-Ahti 1967). Acceptance of two species is appropriate.
