These characters make it very similar to <i>C. scabrata</i>, which, aside from the obvious intercontinental disjunction, can be differentiated by its paired petals limb with a cuneate base and white claw, antherodes with upper lobes very widely obovate and larger than the lower, lower lobes widely oblong to subquadrangular, unequally 2-valved prismatic capsules with verrucose walls, and seeds with ornate testa. Nonetheless, we have yet to be able to confirm if the capsules of <i>C. paludosa</i> (as well as the closely related <i>C. maculata</i> Edgew.) also present ventral valves that only split up to mid-length.
