Synonym: U. inflata var. minor Chapman.[3]
Description
Utricularia radiata is a dioecious annual or perennial that grows as a forb/herb.[2] It has inflated conspicuous petioles and floats suspended on top of water[4] or submersed.[5] This species reproduces sexually and by fragmentation. It produces winter buds/turions and has an unrooted growth form.[6] Its size ranges from 0-1 ft (0-30.5 cm) and flowers are yellow and 0.5 in (1.27 cm).[7] Seedlings lack cotyledons.[8]
Distribution
This species occurs from Nova Scotia, New Brunswick, and Maine, southward to southern Florida, westward to Texas, and disjunct in western Virginia, western Tennessee, and northwestern Indiana. Reports of it occurring in Cuba and South America are in error according to Weakley.[1] Disjunct populations are also reported in southwestern Michigan.[9]
Ecology
Habitat
U. radiata occurs in ponds, depression ponds, lakes, and ditches.[1] In Nova Scotia, it typically grows in 1-3 m deep water and is associated with Brasenia shreberi.[10]
Phenology
In the southeastern and mid-Atlantic United States, U. radiata flowers from may through November.[1]
Use by animals
As a carnivorous bladderwort, Utricularia species can prey upon a range of zooplankton and phytoplankton, including copepoda, ostracoda, Cladocera, Chironomidae,[11] diatoms (Bacillariophyceae), green algae (Charophyceae, Chlorophyceae), dinoflagellates (Dinophyceae), flagellates (Euglenophyceae), and Cyanobacteria.[12] This can include larval parasitic blood flukes (i.e. Schistosoma mansoni) which creates the possibility of U. radiata being used to reduce parasite densities in endemic areas.[13]
