Utricularia cheiranthos is a terrestrial bladderwort endemic to the Northern Territory.

Utricularia cheiranthos is a small bladderwort with flowers around 1-1.5cm in width. The lower corolla lip is divided into five deeply divided lobes that are rounded at the edge. The upper corolla lip is small and bonnet-like. The palate has a raised fused ridge that encircles the opening of the bloom. The flowers are light pink in color with a yellow palate.

The species is known from the Kakadu National Park where it grows in sporadic lowland habitats. I observed it at a new location roughly 75 km east of Jabiru. Here, the plants were growing in a shallow layer of water in dark, organic soils under sparse trees. The patches where they grow lack thick grass. The species blooms towards the end of the wet season and dies as soon as its habitat dessacates at the start of the dry season.

Utricularia cheiranthos is most similar to U. rhododactylos, which shares the general morphology and coloration. Utricularia cheiranthos is distinguished by the shorter upper corolla lip and palate that has a fused ridge (U. rhododactylos has a larger upper corolla lip and has a row of raised palate ridges that are separated from each other). The two species do not overlap in niche with U. cheiranthos growing in shallowly flooded lowland plains whereas U. rhododactylos inhabits shallow sandstone soaks in the escarpment. Utricularia cheiranthos has a similar floral morphology to U. holtzei but is easily distinguished by the pink colour of its blooms (white in U. holtzei).
