Description
Utricularia radiata is a dioecious annual or perennial that grows as a forb/herb.[2] Seedlings lack cotyledons.[3] It has inflated conspicuous petioles and floats on top of water.[4] This species reproduces sexually and by fragmentation. It produces winter buds/turions and has an unrooted growth form.[5] Its size ranges from 0-1 ft (0-30.5 cm) and flowers are yellow and 0.5 in (1.27 cm).[6]
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]
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.[7]
Phenology
In the southeastern and mid-Atlantic United States, U. radiata flowers from may through November.[1]
