 U. inflata is one of the larger suspended aquatic species in the genus Utricularia . Like all aquatic Utricularia , U. inflata has no true roots or leaves . The filiform stolons are the main vegetative " stem " of the plant and can be up to one meter long or longer but are only 1 – 2 mm thick . The stolons are glabrous with 1 – 5 cm between branched divisions . Occasionally the stolons will produce floating air shoots at the water 's surface and tuber @-@ like organs in the substrate . Its filiform leaf @-@ like structures appear to be additional branches off the main stolon and are tiny , filament @-@ like structures that are not true leaves , though the terminology is often disputed among experts . The leaf structures are numerous and anywhere from 2 – 18 cm long , originating from the stolon base into two primary and unequal segments , which are further divided extensively into additional segments . The stalked , ovoid traps , 1 – 3 mm long , are produced on the latter leaf segments and are very numerous .
