Utricularia circumvoluta is a species of bladderwort most notable for its twining flower scape.

The species has small, light yellow flowers roughly half a centimeter large. The lower corolla lip forms a short domed skirt structure. The palate is very broad at the base and steadily reduces towards the tip to form a tringular profile. The upper corolla lip is very much reduced to a short lobe that is barely longer than the calyx lobes. The peduncle is wiry, and twines around surrounding sedges for support.

U. circumvoluta grows in wetter niches like the seasonally flooded grasslands near Darwin where I observed the species. It can be distinguished from other twining species like U. involvens and U. foveolata by its small, yellow blooms.
