Distinctive by virtue of its large flowers and lax, elongate habit. There have been few recent collections of this species suggesting that it may be threatened in Victoria.

Cardamine pratensis, of Northern Hemisphere origin, was collected from the Ballarat district in the nineteenth century and if re-collected, may key out with C. tenuifolia. It differs mostly by being more robust and erect and by forming a basal rosette of leaves.
