The type specimen of Cardamine gunnii possesses distinctive subtuberous tapering roots. Only a handful of Victorian specimens match the type in this respect and all of these were collected more than 90 years ago from south-western Victoria. The only recent Australian collection is a 1968 record from near Mt Gambier in South Australia. Specimens collected more recently and identified as C. gunnii are referable to C. papillata, C. paucijuga or C. lilacina. Cardamine gunnii s. str. is possibly now extinct. It appears to have been a plant of lowland swamps, areas that were cleared for agriculture by early European settlers.
