U. punctata is anomalous in the 'aquatic' group of the genus (i.e. those with dissected setu-lose foliar organs) in both the mode of dehiscence of the fruit and the medifixed bracts. RIDLEY stated that the corolla of his U. fluitans was 25 mm wide but that preserved on the type specimen is less than half this dimension.
