About
A notable perennial suspended aquatic plant, *Utricularia macrorhiza* is easily identified by its large, bilaterally symmetrical yellow flowers, which are larger than those of other bladderwort species.
Field notes
Morphology
A floating plant bearing six to twenty large, bilaterally symmetrical, yellow flowers held on an erect stem. The bladders are used for trapping prey.
Distribution & habitat
Native to North America, found throughout the United States and Canada, primarily in ponds and lakes but also in slow-moving streams and rivers.
Ecology
The plant traps small organisms by triggering hairs on the bladder's pores. When prey brushes against the pore, it opens inward, allowing water to pull the prey in. The pore then closes, and the prey is digested by internal enzymes.
